SLS is Selective laser sintering, one of the most widely used additive technologies.

The principle of operation of SLS is the point sintering of plastic powders with different components by a laser beam.

Some machines sinter powdered metal – this 3D metal printing technology is outdated, but still used. Beam power in production 3D printers varies from 30 to 200 watts.

The method was created in the mid-1980s at the University of Texas at Austin by Carl Deckard and Joe Beeman.

In 1989, the invention was patented by Deckard-founded DTM Corporation, which was subsequently acquired by 3D Systems. In the bowels of the latter, another fundamental additive technology was created – this is laser stereolithography (SLA printing).

So, in this article below, let’s know all about SLS parts, SLS process, SLS Materials, and other additive manufacturing technologies using SLS process parameters.

What Is Selective Laser Sintering (SLS)?

SLS technology involves the point sintering of a powder mixture based on durable plastic parts and other components using a high-power laser. Previously, this method was applied to metals.

It was first created in the mid-1980s by Carl Deckard and Joe Beeman at the University of Texas. In 1989, it was patented by DTM Corporation, which later became part of the 3D Systems brand.

The power of the equipment varies from 30 to 1000 watts. Initially, the polymer powder is heated and then subjected to short laser exposure.

As a result, it sinters with the hardened particles of the lower layer. So, layer by layer and get a 3D workpiece, the same as the original sample loaded into the program.

By adjusting the machine settings and functional parts, you can achieve the required porosity and density of the product.

Unlike Stereolithography (SLA) or Fused Deposition Modeling (FDM) 3D printing methods, it delivers parts with great and also consistent mechanical properties using additive materials.

How Does SLS 3D Printing Work?

All parameters of workflow in the SLS 3D printing method are determined by the manufacturer of the printer. So, this’s how the Selective Laser Sintering (SLS) works:

Printing

The SLS 3D printing machine utilizes a laser as an energy source that selectively melts plastic material of coated powders in a thin layer, fusing them into a fine 3D printed piece.

This method is a part of the Laser Powder Bed Fusion (in short LPBF), among the most reliable and advanced systems in the field of 3D printing or additive manufacturing.

Utilizing a 3D build platform from a CAD software model, the laser melts the bulk material precisely at the predefined parts in the powder bed of the 3D printing or additive manufacturing technique.

After the melting temperature is reached and a solid structure is made using the SLS system, the low volume production, and also a new layer deposition of powdered material are added.

This printing process keeps on repeating layers until the solid-state sintering is completed. It can be used with different binding mechanisms.

Cooling

After the completion of printing with desired layer thickness, the build section needs to cool down slightly inside the print section and then also outside the printer.

This will make sure the best mechanical powder properties and also help you avoid bending in parts. This will also support the material used in the procedure.

Post-processing Methods

The completed parts have to be taken out from the machine’s build chamber and clean of the item of extra powder after being separated.

The SLS powder’s influence can be reclaimed and the 3D printed components can be post-processed further by media tumbling or media blasting.

Since the unfused powder in the method supports the parts while printing, there is no need for reliable support structures.

It makes SLS perfect for complicated geometries, consisting of undercuts, interior features, negative features, and thin walls. Parts built with an SLS machine have superior mechanical features, with strength corresponding to injection-molded components.

Different Kinds Of SLS 3D Machines For Printing

All 3D printers using the SLS method work on the principle described above. They differ in the size of the working chamber, the type and power of the laser, and some design features.

Industrial Models

For many years Selective Laser Sintering has been the working technology of manufacturing. In addition to high cost, devices have several requirements for organizing the workflow.

To prevent oxidation and destruction of the material by the laser, an inert environment is required, respectively, special equipment.

It is also necessary to supply industrial power, air conditioning, ventilation, heating systems, and an area to adjust equipment of at least 10 square meters.

In case we add to all the above requirements the price of industrial machines, starting from $ 100,000, it becomes clear why the equipment was available to a narrow circle of companies.

SLS printers for industrial use are widely applied. They are in demand in many areas, from automotive, engineering, and space industry, and end with small-scale production and medicine.

There are overall systems that can print models whose length exceeds 1m. Industrial printers generally operate on one or more carbon dioxide lasers. It’s quite logical that the larger the assembly volume, the more complex the system will be involved.

Industrial systems, in particular SLS 3D printers, need the use of an inert medium. We are talking about filling the chamber with gas. Most often it is nitrogen or another inert gas.

This is done to prevent oxidation and subsequent decomposition of the powder material used. For this reason, industrial applications include compressed air handling equipment.

Since the systems are powerful, they also require industrial-grade power. And any industrial printer is large. Even the smallest system requires a room with an area of ​​at least 10 sq.m.

Revolutionary Fuse 1

In recent years, manufacturers have begun offering more affordable SLS 3D printers. However, they were imperfect: the quality of products suffered, and there were no ready-made solutions for simple post-processing.

Formlabs has succeeded in developing and launching an innovative product – the Fuse 1 model. The printer is small in size, much cheaper than previous industrial machines, and prints high-quality models.

The model uses 1 laser, the material heats up faster, so gas supply to the chamber and professional ventilation aren’t needed. The printer can be powered by a standard power outlet at the cost of less power than previous generation industrial designs.

The developers have created a unique Surface Armor technology, which is currently in the process of obtaining a patent.

Its advantage is the creation of a semi-sintered shell, the task of which is to maintain uniform heating of the area around the printed objects to form a high-quality surface and better mechanical properties.

Fuse 1’s working volume is slightly inferior to traditional SLS printers, but the device wins in price, compactness, and ease of use.

How Did Selective Laser Sintering Process Come About?

Doctors of Sciences Joe Beeman and Carl Deckard invented the technology of laser sintering of plastic powder in the mid-80s of the 20th century. We can say that this technology was one of the first 3D printing methods to see the light of day.

So far, there have been many innovations, and this additive manufacturing technique has been adapted to different materials. We are talking about glass, plastics, metals, ceramics, and various composites.

Now powder laser sintering technology is available in two variations. In the first case, the laser sinters the plastic powder – this is the SLS technology.

In the second case, metal powder is sintered – these are DMLS and SLM technologies. The principle behind the work of all these 3D printers is the same – the laser sinters or fuses the material.

The difference lies only in the power of the laser used, and also in the fact that metals are oxidized when heated under the action of oxygen, therefore, a special environment (inert gas, vacuum) is required to prevent this oxidation and, accordingly, a decrease in strength characteristics.

All of the above technologies were very expensive not so long ago, which greatly limited their use in printing expensive and non-standard products. To a greater extent, they were used in the medical industry and aerospace. Now everything has changed dramatically.

SLS technology has become popular, available, and in-demand along with other plastic printing technologies (SLA, DLP, FDM). In addition, compact desktop printing systems appeared, which also made SLS more popular.

So, the technology appeared in the eighties of the last century in America. The authors were University of Texas doctors Carl Deckard and Joe Beeman. Since the invention of the method, the range of working materials has gradually expanded.

Now, with the help of SLS-3D printing, ceramic, plastic, glass, and metal products with a different set of mechanical characteristics are created.

The method has two varieties:

• Based on plastic powder – Selective Laser Sintering (SLS)
• Based on metal powder – Direct Metal Laser Sintering (DMLS)

A few years ago, such printing was available only to a narrow circle of enterprises. However, today, thanks to modern developments, SLS production is becoming no less accessible than the usual additive methods, such as SLA and FDM.

Advantages & Features Of Selective Laser Sintering

As for the features, selective laser sintering should be immediately separated from another similar 3D printing technology – selective laser melting (SLM).

The difference between them is that SLS provides only partial melting of the powder, which is only required to combine it into a single element. SLM, on the other hand, melts the particles completely, sintering the powder into a monolithic product.

See how the SLS technology uses elastomeric and thermoplastic materials to build parts with great mechanical properties.

Absolute parts can be utilized to test forthcoming injection molded parts or as end-use, functional components. As for the advantages, the following advantages can be distinguished.

Large build area in 3D printers.

Industrial equipment for SLS 3D printing is usually equipped with a large build area, which allows you to create not only large parts but also small-scale production.

High-quality 3D printing

This technique allows you to almost completely avoid visible layering on the model, and the absence of supports also has a beneficial effect on the quality of products.

Lasers are much more powerful and more precise than the working elements of devices in other types of printers, such as FDM. SLS is the fastest method for additive manufacturing of prototypes and functional products. It allows you to print several products in one cycle.

The software helps to place the models as close as possible on the platform. D-printed nylon products are more durable than plastic, injection-molded, or other 3D printing technologies.

No Need to Build Supports

Selective laser sintering allows you to create products of complex geometry without the need to build support structures. This not only expands the printing possibilities but also has a good effect on the surface quality of the product.

High speed & performance

Because the material does not melt completely, SLS 3D printers work much faster than their other powder counterparts. Higher print speed – higher production productivity;

Design Freedom

Maximum additive manufacturing techniques, like stereolithography (in short SLA) & fused deposition modeling (in short FDM), need technical support structures to simulate designs with some overhanging features.

SLS doesn’t need support structures since unsintered powder covers the parts throughout the printing process.

Selective Laser Sintering printing can build previously unimaginable complex figures, like moving or interlocking parts, items with interior channels or components, and other favorably complex designs.

Generally, engineers design items with the abilities of the ultimate manufacturing method in mind which is called design for manufacturing (in short DFM).

As soon as additive manufacturing is utilized for prototyping alone, it’s restricted to designs and parts that conventional manufacturing devices can finally reproduce throughout production.

As SLS becomes a possible rapid manufacturing process for a rising number of end-use applications, this can discharge new prospects for engineering and design.

Selective Laser Sintering 3D printers can make complex figures that are prohibitively costly or impossible to make with traditional procedures.

SLS even empowers developers to reduce complex masses that would typically need multiple components into a single piece. This helps ease weak joints as well as cuts down the total assembly time.

SLS can take productive design to its maximum potential by allowing lightweight patterns that employ intricate lattice structures unbelievable to manufacture with conventional processes.

Uses Nylon Material Properties

The nylon used in SLS printers can be an excellent alternative to injection molded plastics. It can be used in applications where plastic parts are required, as well as where standard plastics can become decrepit and break.

Proven, End-Use Materials

The key to the versatility and functionality of Selective Laser Sintering 3D printing is the additive materials. Materials like Nylon and also its composites are high-quality, proven thermoplastics.

Nylon functional parts have nearly 100% density with some mechanical properties similar to multiple parts made with conventional SLS printer manufacturing processes such as injection molding for interior components.

Traditional manufacturing using SLS nylon material is a great alternative to common injection-molded plastic materials to make complex geometries. It offers exceptional snap fits, living hinges, and also other mechanical joints than any other additive manufacturing technology.

It’s perfect for functional applications needing plastic parts that’ll last where parts made with other additive manufacturing technologies would spoil and become breakable over time.

What Are The Disadvantages of SLS 3D printing Additive Manufacturing Technologies?

• The time for cool-down is 50% of the total print time. This means around 12 hours of waiting. Thus, it can cause a longer time for production.

• Very costly. The SLS machines can sometimes cost $250,000, or even more. Moreover, the materials generally cost $50 to $60 per kg. Additionally, the SLS machines needed a skilled person to run the machine properly.

• SLS parts produced from the SLS methods come with a coarse surface, thus to fix that, post-processing is needed.

What Materials Are Used For SLS 3D Printing?

The most commonly used SLS material is the Polyamide 12 (in short PA 12), also called Nylon 12. The PA 12 powder price per kg is approximate $50 to $60. Other plastics like PEEK and PA 11 are also obtainable, but these aren’t as commonly used as PA 12.

Polyamide powder for SLS parts can be supplied with different additives to enhance the thermal and mechanical behavior of the created SLS parts.

Instances of additives consist of carbon fibers, aluminum, or glass fibers. Materials loaded with additives are typically more brittle as well as can have favorably anisotropic behavior.

Pros
• Great chemical resistance
• Great mechanical properties

Cons
• Rough, matte surface finish

Polyamide 11 or PA 11 Material

Carbon-fiber-filled nylon or PA-FR Material

Pros
• Superb stiffness
• Increased weight-strength percentage

Cons
• Highly anisotropic

Stages of SLS-3D Printing

Designing & Preparing the Project File

To start a project, you need to use any CAD software file available by scanning. Every software on which the SLS 3D printing machines work makes it likely to cut the item into layers, calculate the printing period, organize objects in a provided order, and also configure the print settings.

As soon as ready, the software transmits commands to the 3D printer through a wireless connection or cable.

Preparing the 3D Printer

Preparations differ based on the model of the 3D printer. Previous generation devices need special skills for maintenance and operation. The manufactories of the Fuse 1 device have made the SLS printing way easier than before.

Print The Product

After the initial work, you can start the process. The complexness of the task defines the printing term: from a few hours to many days.

After finishing printing with good mechanical properties, the model should be left in a cooling compartment to avoid shape loss and to improve the mechanical parts. For the following work cycle, you even can use an exchangeable build chamber for the cooling process.

Recovery & Post-Processing

The ultimate procedures take time as the SLS 3D technology doesn’t involve the usage of supports, therefore the time is devoured at their disposal.

The cooled items are taken out from the chamber as well as cleaned of all residual powder on the product.

The polymer powder is then filtered and also processed for additional usage. Material properties are negligibly decreased, so a blend of new & old powder beds is utilized for the following printing cycles.

The raw materials are a significant benefit of the SLS 3D technology. Thus, different devices are utilized to reconstitute, store, and blend the powder bed fusion.

Extra Post-Processing Of SLS 3D Printing

Cleaned items can be immediately used. But for various projects, extra processing of items may be needed.

For instance, to remove coarseness from the surface of the SLS parts, the manufacturer suggests blasting or tumbling.

In case you need to adjust other parameters, like water resistance, color, and also electrical conductivity, items can be covered with numerous compositions.

The Main Benefits of The Procedure

• High quality
• Performance
• Development of engineering abilities
• Reliable materials
• Design convenience

3D printing depending on SLS doesn’t need the formation of supports, unlike several other printing methods, for example, SLA and FDM.

Thus, Selective Laser Sintering SLS printers make it potential to produce parts of complex configurations, with internal holes, protruding elements, and also other features.

Prospects For The Development Of Technology

SLS technology was originally used for rapid prototyping, but gradually its scope expanded. Selective laser sintering has shown excellent results in small-scale production of finished products, master patterns for casting, etc.

Not so long ago, another interesting area of ​​application of selective laser sintering was the manufacture of art objects.

The technology continues to develop: new materials are being introduced, the power of laser radiation is increasing, and developments are being made to use several materials in one technological process.

SLS printers are becoming more productive, smaller, and easier to use, while desktop models aimed at-home use have already appeared on the market.

The potential of selective laser sintering is enormous because this method opens up the scope for the implementation of the most promising technical and creative ideas.

Application Industries

Selective laser sintering has been widely used in various industries:

• Mechanical engineering
• Aerospace industry
• Foundry
• Construction
• Engineering design
• Architecture, art design

It’s essential in the production of pipe hoses, functional prototypes, gaskets, insulating washers, art objects, elements of power plants, etc. Especially high efficiency of the technology in small-scale production.

Originally, it was utilized for rapid prototyping, but slowly the scope has largely expanded. The possibility of the technology is quite large and hasn’t yet been completely explored.

FAQ Selective Laser Sintering 3D Printing Guide

Following are common questions on selective laser sintering 3D printing.

What Does It Mean By Additive Manufacturing Technologies Used In SLS?

Selective Laser Sintering (SLS) is a powder-based 3D printing or additive manufacturing technology that utilizes energy equipped with the laser to melt as well as fuse the powders. Then stack one layer after another to create a printed part depending on 3D model info.

What Is Direct Metal Laser Sintering or DMLS?

The 2 most standard powder bed fusion methods today are plastic-based and metal-based. And the metal-based is known as the Direct Metal Laser Sintering or in short DMLS, or even known as selective laser melting (in short SLM).

BOTTOM LINE

SLS process printing equipment is equipped with large build chambers (up to 750 mm), which allows you to produce large products or entire batches of small objects in one printing session using traditional manufacturing methods.

It thus offers excellent mechanical properties of the finished product: high strength, the accuracy of construction, and high-quality surfaces. No backing material required: The process is virtually waste-free and unused material can be reused for printing.

High performance: SLS printers do not need to completely melt the material particles, which allows them to work much faster than other powder 3D printers.

Multiple thermoplastic polyurethane (in short TPU) and nylon-based product materials are obtainable, which make highly stable final SLS parts that require heat resistance, flexibility, chemical resistance, or dimensional stability.

Whenever you ask a 3D printer owner about their printer or the device’s major advantages, the person will inform you about the high-quality printing and the power to make prototypes.

However, when you will ask about the disadvantages, the answer typically follows about some disadvantages in the printer’s design: someone isn’t happy with an insufficiently rigid frame, and a few of them have also complained about too slow printing rates.

In the article, we are going to understand what advantages most 3D printers have and find out what disadvantages their owners have to face.

So, let’s now know what are the advantages and drawbacks of 3D printing over traditional manufacturing processes. 3D printing gradually taking place over the traditional manufacturing methods.

Let’s get to now know is it valid to follow 3D printing or the traditional manufacturing process or injection molding for the mass production process.

What Is 3D Printing?

3D printing technology also called additive manufacturing process, is a term that encapsulates several different manufacturing methods that are unified singly:

The capability to produce custom components by slowly making them out of basic material. 3D printing is an integral technique in modern manufacturing over the traditional manufacturing techniques, helping users to make custom parts easily and quickly.

These parts are easily made using complicated geometries and shapes and also serve a wide range of applications in the defense, aerospace, medical, and automotive industries using rapid prototyping.

Additive technologies bear unique advantages as well as disadvantages compared to other manufacturing methods, like CNC (Computerized Numerical Control) machining, where bulk materials are decreased to their ultimate shape through cutting or manufacturing methods.

The article below will explore several advantages and drawbacks of 3D printing.

Advantages Of 3D Printing Additive Manufacturing

Let’s begin with the advantages: 3D printing allows you to relatively inexpensively and quickly produce the desired prototypes with high accuracy, independently adjusting the settings of the printer and choosing the best parameters.

Unlike traditional manufacturing processes, 3D printing manufacturing processes have some unique advantages. Let’s find out each advantage of 3D printers in more detail over traditional methods.

Less Waste, More Sustainable

In 3D printing, only the needed limited materials are utilized to make specific parts, as it’s an additive process.

This’s different from the traditional processes, in which massive masses of non-recyclable materials are cut to make 3D parts. So, the overall waste of 3D printing is lower because the printer uses as much product as needed and you only spend for what you require.

3D printing (additive manufacturing process) meets the major standards for sustainability which are – reduce, reuse, & recycle.

Cost Reduction

Large-scale projects with a large number of 3D printed parts aren’t cost-effective, but additive manufacturing remains more profitable than traditional technologies and other methods.

Many manufacturers use 3D printing for prototyping or short runs. For instance, it’s much more beneficial for jewelers to print wax prototypes of jewelry than to cast them from metal. The plastic used in 3D printing is relatively cheap, and even the simplest 3D printer can help you save money.

Provides An Enhanced Competitive Advantage

Old manufacturing methods are typically characterized by inadequate design, which can cause poor-quality prototypes.

It means that the product quality can’t be assured. However, this isn’t the case when you use 3D printing technology, as the item is made in a serious step-by-step approach, which guarantees outstanding product quality and design process.

3D printing also permits for greater consistency as compared to other production methods, while still delivering consistently high-quality parts.

This’s possible since errors are noticed immediately, allowing to decrease the generally wasted materials and also defective parts.

Thus, this essential technology provides parts in a batch that are not incompatible or defective when compared to other parts.

Reduce Time

3D printers can reduce the spent time significantly on each project. different from traditional production methods, while using additive technologies, the whole printing process may take several days or weeks, and the mass customization from CAD files can be printed in a matter of hours.

Some automobile manufacturers have chosen to optimize their products by starting to create parts to order.

This approach lets you take mass production to a new level: now you don’t need to have a lot of stock of different parts, since you can print them simply as required, immediately editing individual files.

Freedom of design

3D printing permits for the design to be as per the operator’s desire and print of more complex geometry or shape than traditional manufacturing processes.

Further traditional manufacturing technologies have design limitations that are not the case in 3D printing. You can print even the most complex designs in these printers.

Reduce Errors

The appearance of the product virtually or on screen can’t resemble the real feel of a prototype that one can experience using 3D printing technology.

Therefore, it’s possible to touch & feel the product’s physical prototype and check whether there’re any errors in its design or not. If there’s an error, you can edit the CAD files to print a new version later.

Sustainability

Even though conventional manufacturing processes are slowly becoming more endurable and sustainable with time, the 3D printing process has a few environmental benefits over its more aged counterpart methods.

This modern method is improving constantly, and specialists predict a thrilling future where customers can order customized parts depending on their requirements while decreasing material loss.

3D printing’s capability to decrease material loss and also unnecessary abundance makes an excellent process in case we want to make a more green economizing and enhance sustainability in the industry of manufacturing.

Option To Prototype

Conventional manufacturing methods rely on shaping and cutting techniques to make the preferred shapes, which isn’t only hard but also costly.

Fortunately, you will not have this issue with 3D printing technology, and all you require is the right support material to create a product at very low costs.

To print any product using a 3D printer, you need to create a CAD file physical prototype. The 3D printer lets you create hollow shapes, and have severe undercuts, which is impossible with any other traditional methods.

Production On-Demand

Different from subtractive manufacturing, a 3D printer doesn’t take up much space as products can simply be printed as soon as needed or ordered.

Not just you’ll save on labor costs and other costs with this, but you’ll even save space as you only produce large volumes when required. All 3D design files are kept in a virtual space, from where you can print them using a 3D model as a CAD or STL file.

Improvements In The Medical Sector

3D printing has improved the medical sector as it’s nowadays possible to print organs of the human body such as the kidneys, liver, and heart.

Hearing aids or printing prostheses isn’t any longer an inquisitiveness for anybody. Additionally, more investigation is going into how 3D printing can help the healthcare sector.

Moreover, new therapeutic techniques and tools created through 3D printing fetch new levels of personalization and comfort to the treatment.

And this recently available technology, also, allows physicians to achieve a better experience of complex subjects and offers unique tools that can eventually cause a higher measure of care.

Typically, conventional manufacturing processes are more affordable for large-scale creation, but the expense of 3D printers is turning competitive for slighter production runs.

This’s likely to save millions of dollars in the medical sector. This modern method will reduce costs of manufacturing and production costs by improving efficiency, increasing resources, and also eliminating traditional development processes.

Produce Lighter & Stronger Parts

Plastic is mainly used for 3D printings, although there’re also other materials obtainable for 3D printings. 3D printings allow the production of complex shapes that are way lighter than products made in other manufacturing processes.

In the automotive and aerospace industries, this’s a vital element as the usage of lightweight materials allows for improving the efficiency of fuel.

3D printed products can be created from materials that have certain characteristics like higher strength, water repellency, and heat resistance. Plastic materials like PLA (Polylactic acid) can be mixed with wood or even metals for unique properties and finished products.

3D Printing Is Very Accessible

The benefit of 3D printing tools has improved in recent years because of greater accessibility. 3D printings and modelings are accessible, adaptable, and affordable technology.

Makers have developed a wide range of free, easily obtainable 3D modeling software applications as well as warehouses of easily usable models.

Eco-Friendly

Maximum energy utilized in 3D printings comes mainly from warming the nozzle to melt the plastic (such as PLA, ABS), and also from heating the warmed printing bed in case you’ve got one.

PLA filament material melts at a lower heat than ABS material, therefore needing less power to complete the printing procedure. However, in case you choose ABS filament material for your product, you’ll also need a heating bed to stop warping, adding extra heating needs.

Picking PLA filament material is surely the low-energy alternative. Moreover, these materials used in 3D printing are all biodegradable. So, you can recycle and reuse the material. That is why 3D printing is known as an eco-friendly process.

Advantages of 3D Printings in Construction

The industry of construction presently causes an extensive amount of waste, as well as an improvement toward sustainability, which is quite slow.

Because of the complexness of supply chains in this field, green management has had a narrow effect. Construction assignments can involve several different businesses, making it exceedingly difficult to guarantee a sustainable method is used throughout the entire supply chain.

However, disruptive technologies like 3D printing come with the potential to transform the method that which products are invented and manufactured, mainly changing the construction of supply chains.

3D printing is helping the construction industry and the industry is gradually becoming leaner, more sustainable, and more efficient.

Disadvantages Of 3D Printing

Despite several 3D printing advantages, it isn’t an excellent production procedure for every situation.

This way, you will learn if the advantages compared to traditional manufacturing methods are more or significant disadvantages. 3D printing might not be the ideal procedure for your task if you can’t reimburse for the subsequent disadvantages.

Initial Costs Of Printers

3D printers, especially the industrial ones are on the expensive side. This type of 3D printer costs you around tens to hundreds to even thousands of dollars.

Although these 3D printers are made to do several things of high quality. But looking at the initial costs of the printers and costly material needed it is quite hard for everyone to afford it. So, the initial investment dramatically affects 3D printing methods.

Post-Processing Methods Of 3D Printings

While printing, layers are observable on parts. If these are additional parts, polishing doesn’t play a role in the operation.

In case this’s the ultimate product, then it should be polished. So, printing a product isn’t all you need to do. Rather, you need to perform post-processing to get a perfectly finished product. So, it is a time-consuming and hard process.

Limitation Available Materials Needed

When 3D Printing can produce objects in a selection of metals and plastics, the available preference of raw material isn’t comprehensive.

This’s because not all plastics or metals can handle the temperature enough to let 3D printing work properly. Additionally, many of these materials can’t be recycled as well as very few of them are food safe. Only a few selected raw materials can handle the heat.

Special Skills Needed For 3D Models

The technology of 3D printing is still unknown to many people, and there are still several trial & error details needed when making 3D items. Despite the 3D printing potential, 3D printers aren’t easy to operate.

Nevertheless, experts believe the 3D printing technology has a potentially abrupt learning curve that’s being analyzed. This technology is not everyone’s cup of tea. You need to have a certain skill set to operate the machine properly.

Decrease Manufacturing Jobs

Manufacturing job losses are one of the most significant disadvantages of 3D printing. The usage of 3D printing lets you create complex designs and prototypes within just a few hours with easy steps.

Most manufacturing steps are eradicated and this allows savings on labor costs since fewer people ought to be employed to finish the manufacturing process.

Finally, this causes the removal of manufacturing jobs. This can be significantly worse in nations where the maximum of citizens rely on low-skill jobs for creating parts.

Certainly, manufacturers and operators of 3D printers are needed, which partly recompenses for these failures.

Limitations on Build Volume Of Manufacturing Process

Maximum 3D printers nowadays have little build chambers. This drawback also applies to industrial-grade products.

The injection molding presses as well as mills have a significant ability to create items of a substantial size.

In case someone desired to follow a comparable manufacturing method using the printing procedure, then the final product would require to get glued depending on the fractional dimensions that could be created.

It means the production time will go up to produce the larger products, reducing the time and cost advantages that are achievable with smaller parts or prototypes.

Struggles to Manage Large Volume Orders

In case you need a huge quantity of products in a short period, then 3D printing won’t be the perfect production procedure you want to pick.

Unlike injection molding, you can’t print several items in one batch. Once you complete the design, you need to print the products one by one.

You need to wait till a product is completed. Moreover, the printing bed needs to reach a certain heat. Thus, there will be more waiting periods.

May Not Pass Through Strength Tests

3D printing or additive manufacturing lets products get printed layer-by-layer that stick to each other throughout the creation procedure.

It means these products can often break or separate under particular stress levels or even with part exposure.

This problem is an even greater issue when using the Fused Deposition Modeling (FDM) method. You can utilize polyjet or multijet printing to make materials that have further solidity, but that procedure causes a brittle final product.

In case you avoid delamination for the project, then the injection molding procedure is going to be the best solution. This produces homogenous products in methods that are not necessarily achievable through 3D printing techniques.

Uneven Surface Finishes Of The Production Process

Since 3D printers generally build products layer-by-layer, they sometimes show observable steps on steep surfaces.

These visible layer heights can be effective for specific processes. It can be frustrating in case you wish to make a further aesthetically acceptable part.

A few post-processing methods can fix this problem, such as vapor smoothing, however, remember that the natural finish of the surface of maximum printed products can’t contend with products produced via CNC machining or injection molding.

Lower Accuracy Tolerations

A few 3D printers have very lower tolerances. This results in final products that are separate from the original prototype.

This’s a potential issue that’s presently connected to the operation of 3D printers operated. While the issue can be improved by post-processing, the extra production cost is desired.

Size Restrictions

3D printing is not well fitted while you need products at an end of the size scale; you’ll then run the chance of making a product that’s too big or too tiny.

For instance, it’s hard for a 3D printing bed to create parts shorter than a peanut as well as bigger than a soccer ball.

Sadly, the smaller or larger the product you prefer, the less accessibility there will be for that product because some 3D printers can perfectly print at that smaller or larger scale.

Disadvantages In The Medical Field, Organs, Medicine, Prosthetics

3D printers do not always deliver top-of-the-line outcomes. Three-dimensional solid objects can differ slightly in size, and a few levels of creation noise — such as bumps or texture when a surface ought to be very smooth — may be presented in the manufacturing process.

If that is the case, the irregularities and noise would need to be machined out by a worker even before the products would be permitted to come into contact with patients.

Although 3D printing has a few benefits in the medical field, it likewise brings a few disadvantages with it.

There’re still many disadvantages that aren’t on this list. However, there are a few major disadvantages that medical practitioners and pharmacies should know about 3D printing.

Pharmaceutical businesses can’t possibly control the efficiency of 3D printing operations. Additionally, they need to think of the potential liability implications of the product.

The rapid growth in propagating fake pills is among the greatest problems with 3D printing. Similarly, 3D printers are being utilized by hackers to make fake medicines quicker than the traditional manufacturing methods.

Disadvantages Of FDM 3D Printing

The main drawback of Fused Deposition Modeling (FDM) 3D printing is the low resolution of the technology.

Not just does FDM’s fairly dense layer height mean that it isn’t perfect for products with small components, but it even means that completed products will probably have rough surfaces as well as need post-processing to get a smoother product.

Although vapor smoothing, epoxy adhesion, and gap-filling can enhance the appearance of the part, these procedures will also increase the times of production.

Consequently, Fused Deposition Modeling (FDM) 3D printers are not perfect for creating products that need a high resolution or smooth finishes.

Since Fused Deposition Modeling (FDM) 3D printers generally place filaments one layer by another in a certain direction, the resultant prints are anisotropic as well as prone to infringement, particularly where the layers should meet one another.

For instance, FDM parts can readily break when meeting compressing forces similar to their layers. Rotating between layers of printing on the X-axes and Y-axes can support a print, however, for maximum applications, the more delicate weight of a Fused Deposition Modeling (FDM) part makes up for a small reduction in power.

Support structures are required when printing with Fused Deposition Modeling (FDM), this means that the prints will need more time, post-processing, and material than in case they were created with a procedure such as HP Multi Jet Fusion, which doesn’t need support structures.

There’s a wide range of 3D printing techniques that need support structures, even though they can barely increase timelines and costs.

Disadvantages Of 3D Printing In Construction Field

Maybe the biggest problem with the general acceptance of 3D printing in construction fields is the high initial cost of buying or renting such tools and also the logistics concerned in getting these big 3D printers to the site of construction.

Construction labor deficiencies are already an issue, and finding skilled workers to operate 3D printing construction conditions can prove to be more difficult in the future.

The environmental factors, weather, etc. are all situations that can make 3D printing technology in commercial buildings more of a failure than a success. Similarly, quality management in buildings can already be a problematic matter.

In case not continuously observed and managed by real human beings, quality in the 3D printing technology could end up being quite an expensive procedure.

For a long time, silicone hasn’t been utilized in 3D printing.

Unlike metal-containing compounds and thermoplastic resins, silicone is hard to heat and reach the required melting point, which initially made it inappropriate for this production technology.

The situation changed completely in 2016, when Wacker Chemie, a recognized world leader in the chemical industry, introduced the first silicone 3D printer.

This growth has opened up great opportunities in many areas, especially in medicine and healthcare, where silicone has long been used due to its biocompatibility, mold release, and tear resistance.

Today, silicone, along with metals, ceramics, and thermoplastics, is among the materials for 3D printing without any leaks and/or air bubbles like before.

Given the comparative cost of casting silicone injection molding, especially in the manufacture of specific parts or piece production, silicone 3D printing has an exciting future.

Using silicone two-part molds for bulk production has been there for ages, however, there’s more to learn about this method.

Molds let you produce the same parts like supplies, boxes, rubber bands, popsicle sticks, etc, over and over again, but getting the product quality ideal every time might be challenging.

Is Silicone additive manufacturing technology the solution? Let’s now find out why you should start using a Silicone 3D printer and Additive Manufacturing to build your mold star.

What Is Silicone And Why You Should Consider Using Them?

Silicone is the name of a group of polymers made up of chains of alternating silicon and oxygen atoms.

Organic groups are attached to silicon atoms, resulting in materials with special properties – resistant to chemical attack and different temperature conditions.

Due to these properties, silicone is often used for the production of medical objects, which must be resistant to various fluctuations in environmental conditions.

Traditionally, silicone is used in the production of thermoplastic injection molding technology. In this case, a hollow blank space is made in the form of the desired object, into which you need to pour slowly the polymer melt to cast your product shape.

The poured liquid polymer is held in the preform under pressure until it cools completely. Next, the casting silicone blank is opened and the finished product is removed from its blank space.

Silicone is excellent for injection molding due to its unique physical properties and it offers multiple copies-making opportunities.

However, unlike additive 3D printing, injection modeling of objects has a high cost and does not allow you to create fine details. But in 2016, chemical company Wacker Chemie announced that it had found an effective way to 3D print with silicone.

Shortly thereafter, Envisiontec, Carbon 3D, and Fripp Design also introduced equipment and materials to the market specifically designed to work with silicone on 3D printers.

Present Silicone 3D Printing Technology

3D printing with silicone is similar to printing with plastic or other materials that must remain liquid during the printing process.

Instead of the hard, filamentous filament (fiber) usually fed through an extruder, the silicone is pre-melted and forced through the extruder in small droplets that are stacked on top of each other. So, here check out the measure for Silicone 3D printing.

Drop-On-Demand (or ACEO)

ACEO is the name of the brand given by Wacker Chemie for its in-house dropjet resolution of 3D printing with silicone.

The Aceo technology 3D prints with silicone by planting 1 voxel of silicone material (silicone and UV triggering binder) simultaneously.

After every single layer, the UV light source triggers the binder as well as then the following layer is produced.

Support designs are printed with some water-soluble materials to be liquefied later in the post-processing of the surface. This helps produce smooth cured creation.

Adjusted Resin-Based 3D Printing (Carbon, Spectroplast, Envisiontec, Henkler)

The adjusted resin-based 3D printing process for silicones is utilized by multiple organizations.

Almost all such techniques combine liquid silicone along with a photosensitive resin base structure. The methods typically involve the subsequent step in detail:

• Design the item for 3D printing in a custom software customized for the silicone 3D printers by the manufacturers;

• Load the file up on your 3D printer;

• Then fill the mixture using the proprietary silicone resin;

• Now let the printer do its things on its own;

• And then do the post-processing (normally in some sort of oven) to achieve smooth silicone parts.

Spectroplast just offers its technology as on-demand services. While Envisiontec and Carbon are targeting use for their high-end high-cost machines in the Industry.

Henkler lately entered this 3D printing world by way of the resin line consistent with both Envisiontec and Carbon 3D printers for industrial use.

Liquid Additive Manufacturing (in Short LAM)

LAM or Liquid Additive Manufacturing is a process similar to FDM or Fused Deposition Modeling 3D printing, however, with some changes to make it appropriate for liquid silicone use.

Liquid Additive Manufacturing can be considered a curing-based Fused Deposition Modeling function.

• In that, LSR (liquid silicone rubber) is extruded onto the build plate

• Then the extruded layer gets heated up with a halogen lamp to help molecular cross-linking.

• Hence, converting that liquid silicone to a solid form.

LAM is created by German RepRap with the Company named Dow Chemical. German RepRap presents a LAM-based 3D printer under the brand innovatiQ.

Is 3D Print Silicone Molds/Mold Box Even Possible?

3D-printed silicone is certainly a fact now. However, to say that it’s either effortless to print, or readily accessible for 3D printing lovers would merely be inaccurate. There’re some high-end 3D printing techniques adapted especially to silicone 3D printing.

However, none are easily available for customer 3D printers. Rather, almost all of the participants in the 3D printed silicone world have chosen to deliver either on-demand service for 3D printed silicone or significantly inhibitive and costly 3D printers on some contractual bases.

How To 3D Print Silicone Molds Using Liquid Silicone?

Many enterprises have changed extruders available in the market for printing. Here, rather than a filament made of other materials like plastics, metals, etc. being extruded, it is a paste.

Nevertheless, the most straightforward method to 3D print silicone is via the usage of molds.

• Preferably, you’ve got the liberty to pick from any material for 3D printing to make your molds. Both ABS and PLA work nicely.

• Let’s now use the instance that you wish to make a phone case using silicone. First, while designing the molds in CAD software, you’d include a cube. After that cut away the desired design from the cube.

• Now we’ve got the hollow of the case. After that, cut that said cube in half. This will help you to print in 2 separate parts.

• Put the first half and second half together to create a bind at the top, as well as there you’ve got it – your silicone 3D printed molds!

• Then, you will require a mold release agent

• So, pour your two-part silicone which will turn solid after a specific time.

• Wait until the material sets before peeling the mold apart and revealing your completed product.

Application of 3D Printing Silicone

The areas of application of silicone stem from the diverse properties of the material:

Resistance to aggressive environments and the absence of toxic effects on body tissues, that is, the biological compatibility of silicone, have found application in various branches of medicine, especially as a raw material for the manufacture of individual implants.

Other uses include the production of skin-contact products: respiratory masks, hearing aids, spectacle nose pads, ear pads, wristbands, and many other permanent wear devices.

Resistance to extreme temperatures and solar radiation makes silicone suitable for the automotive industry, as well as for the production of items intended for outdoor use. Example: plugs and hoses.

The elasticity of silicone allows it to be used in areas where high flexibility and resilience are required, for example, in the production of insoles for running shoes.

The transparency makes silicone useful in optical equipment. They make contact lenses out of it.

The unique waterproofing properties make silicone an ideal material for sealing joints in the automotive industry, as well as for the manufacture of seals in hydraulic systems.

What To Look For When Buying Silicone 3D Printing Equipment?

If you choose a silicone 3D printer, then choose a device that has the following characteristics:

Jet Extruder.

An extruder system with a regular feeder will not work with silicone, so check how your chosen printer performs with different materials before you buy.

Internal Heater & Pump

Because 3D printing uses liquid silicone, look for a machine whose extruder uses both a heater and a pump. This will ensure that the silicone has the correct and even consistency and will also prevent clumps or material from getting stuck as it passes through the nozzle.

Short Straight Lines

The heated silicone should enter the extruder as quickly as possible. Reducing the distance and number of turns on the way to the nozzle will allow the silicone to flow evenly and without external assistance.

The closed printable area is a mandatory attribute of a 3D printer for working with silicone since the vulcanization process is implied.

The glass chamber contains an ultraviolet emitter, the ultraviolet in such machines is responsible for vulcanization, so this is an important feature if you are going to use a 3D printer for silicone printing.

Dosing Systems

To work with silicone, it is desirable to have a dosing system such as ViscoTec or similar. The systems are based on the “endless piston” principle, transporting and dosing the material is carried out almost without pulsations and with a minimum shear force. These requirements are valid when it comes to inkjet printing with liquid silicone.

Benefits Of 3D Printing With Silicone And Is There Any Future?

Silicones are abundantly used almost in all manufacturing industries here in some form or way. Generally, silicones are used in machinery as adhesives, sealants, grease, and lubricants; in prosthetics, biomedical implants, and robotics.

Also a rising number of customer goods like phone cases, textiles, kitchenware, etc. Intrinsically then, the possibilities of 3D printed silicone influence so many enterprises.

• Using silicone 3D printing we can develop admiringly engineered seals that reduce material usage while increasing airtightness.

• We can also see artificial organs and biomedical implants custom-designed to the micron to serve the requirements of a patient.

• Consumer products that can be customized 3D printed; fashion accessories and clothing that can be made to size in no time; flexible, soft robots that can do everything from creating the morning coffee to helping the old people in their daily lives.

The effect of silicones illustrated a truly remarkable achievement in the artificial materials world. Add the charm of 3D printing as well as it’d certainly not be a modest statement to call it just “revolutionary”.

The future of silicone 3D printing has been promising in a long term. 3D-printed silicone, when still in its initial stage, vows to make that tomorrow even more promising.

Cost of 3D Printing With Silicone

The precise expenses are hard to establish since 3D printable silicone isn’t easily available at the customer level.

The proprietary product like Aceo by Wacker Chemie, Spectroplast with ETH Zurich, and 3D Alchemy founded in the United Kingdom are all presented as 3D printing on-demand services with ca ustom quotation.

Alternatively, in case we’re to look at proficient 3D printers obtainable for 3D printing with silicone, then only the 3D printers can cost around $25,000/year for Carbon’s silicone-polyurethane resin that is capable of Digital Light Synthesis (in short DLS) 3D printers.

LAM or Liquid Additive Manufacturing 3D printers produced by German Reprap in association with Dow chemical enterprise also run around $50,000 to $100,000.

Sufficient to state, 3D printed silicone at present is costly and typically only suitable for pro-grade usage or engineering.

The on-demand service is certain to 3D print your design or also good old 3D Benchy in silicone. However, expect a bill way higher than your normal Polylactic Acid or PLA print.
