Or do you have lots of notes from school and need an organizer for it? This DIY project, a 3D printed desk paper tray will be a good addition to your working space. It has three different trays. One for general purpose, another for pens, clips, and coins the third one for visit cards.

#4 Water Diverter

Other useful things to 3D print is a water diverter. This water diverter fits a tap aerator with a diameter of 23.5mm. It has an annular manifold that prevents the aerator from choking and keeps it working smoothly for a steady aerated stream.

#5 Rigid Heddle Loom 

If you love weaving fabrics, you can 3D print a rigid heddle loom. One user already did it using a 3D printer and some raw plastic materials. The user used a screw to keep the whole thing.

The creator used an openSCAD, a 3D modeller program to design it. For those who love weaving, 3D printing a rigid heddle loom will be useful for sure.

#6 Guitars

If you love music, in particular, guitar, I’m pleased to inform you that you can also 3D print it. Whether it’s acoustic guitars or electric guitar, it is possible with 3D printing. In fact, creating guitars with 3D printing is cheaper, easier and more convenient.

Musical instruments are among the cool things to 3D print. For musicians looking for 3D printing ideas, I encourage you to try 3D printing your favorite instrument. After all, is there something cooler than a 3D printed musical instrument like guitar?

“Typically, musical instruments produce prototypes using wood or metal, which is understandable but can be costly, time consuming, and leave room for error. 3D printing prototyping allows for greater control and the ability to quickly make miniscule or significant changes that are perfectly accurate. This process can eliminate countless hours of trial and error while reducing production costs and generating a quality model,” said 3D Printing Solutions Australia’s CEO Michael Tyson

#7 Hand-made camera lens

Cameras are among the most popular devices today. In fact, most, if not all, own one. If you love photography, 3D printing your own camera lens is possible.

One did it using acrylic to replace the glass on the lens and other tools to combine the small parts together. The great thing, it works!

You can also 3D print a camera slider. Feel free to try it if you need one!

But Natural Machines co-founder Lynette Kucsma is positive that the food printing kitchen appliance will be as ubiquitous as the microwave oven.

#49 A Working Gun

Guns are expensive, but if you feel that you need one for self-defense, 3D printing a gun is possible. With regards to the legalities of 3D printing a gun, the Gun Control Act of 1968 mandated that anyone who engaged in the business of dealing firearms must be licensed by the federal government. In addition, firearm dealers must perform a background check for their prospective buyers and maintain records for all sales. 

The act does not prohibit any individual from making a gun for personal use. A non-licensed person may make a firearm, provided that it is not for sale and that he is not prohibited from possessing one (felon convicts). On the other hand, Federal law imposes no restrictions on non-licensed possessors. Thus, if you 3D print a gun, you do not need to register it or go through a background check.

#50 Buildings

Yes, 3D printers can also make buildings. A Chinese company constructed two buildings with the use of a 3D printer. They used recycled industrial waste for their material.

The company’s printers were 6.6 meters tall and the ink was a mixture of cement and glass fiber. The said printers can manufacture buildings up to 12 stories tall.

One was a 1100-square-meter villa and the other a six-story residential block. It might not sound appealing to live in, but the Chinese company said that the buildings were safe to occupy.

#51 Car

Are you wondering if you can 3D print your own car? If you do, the answer is a resounding “yes”!

The first 3D printed car, Urbee was created in 2011. Local Motors is also making its own. In fact, they are developing a 3D-printed car that exceeds the FMVSS standards by 2017.

If you want to know more about 3D printing, feel free to check our homepage.

3D printing offers tons of benefits in the fields of medicine, engineering and business. This page will help you understand and appreciate the different 3D printing applications.

What to make with a 3d printer? What can you print with a 3d printer? Have you asked yourself these questions?

If you are really wondering what this technology can deliver, then this page is for you. We will give you an idea what to print with a 3D printer.

3D printing capabilities and 3D printer uses are unlimited. It is used in the packaging industry, automotive industry, aircraft and health care. To better understand the power of 3D printing, here’s a list of the benefits of 3D printing.

#1 More Affordable

The traditional ways of prototyping injection mold tools and production runs are expensive. The best 3D printer offers more affordable options to create parts and tools through additive manufacturing at rates much cheaper than traditional machining.

Take for example, in the medical field, 3D printing surgical tools like clamps, forceps, hemostats and scalpel handles are much cheaper than buying the stainless steel counterpart.

In addition, 3D printing prosthetics are low-cost compared to the traditional ones. Prosthetic for certain parts of the body like hands are subject to so much wear and tear that producing it may reach up to $ 10,000, which is quite expensive.

For young children, who can outgrow their prosthetic limbs in just a few months, the traditional method is costly and not practical.

#2 Mitigate Risk

If you are building a project, you can 3D print a test prototype first before investing in an expensive molding tool. In this way, you can redesign it or alter the existing mold if necessary.

#3 Quick Production

Traditional prototype manufacturing requires tooling and machining. You have to pay individuals for their labor and have to purchase expensive equipment.

The whole process may take weeks. The worse part, your first prototype is never your last, you have to redesign it and experience the same struggle again.

It is difficult to build a good business with traditional prototyping because so much time is wasted. Everyone from CEO to the client gets frustrated every time he waits for the designs to be prototyped.

However, 3D printing will only take hours. If you build it at the end of the day, you can expect it the next morning.

When the designer is done with the design, you can convert it to a file readable by the printer and print it. The process needs no intervention.

No one will be waiting and products can be marketed faster. Also redesigning your prototypes can be done quickly. The whole process will not even take a week.

#4 Easy to Customize

Industries use mass-production to manufacture their products. This means that all products use the same mold and will come out with similar shape and design from the assembly line, which makes it difficult for one to be unique.

However, with 3D printing, you can personalize anything by tweaking a part of the prototype, so it can cater your needs. For instance, customizing 3D prints are used in medical and dental industries.

#5 Tool-less

This is one of the benefits that most manufacturers are taking advantage.

#6 Producing New Shapes And Structure Is Easy

The traditional manufacturing method relies on mold and cutting technologies to produce the shape they desired. Before, adding holes that change direction, unrealistic overhangs or square interior cavities are difficult to achieve.

In fact, 3D printing has been used to produce implants that resemble bones, skulls, aerodynamic parts and unique-shaped furniture and jewelry.

With 3D printing, the possibilities are endless. The only limitation is one’s imagination.

#7 Diverse Material

Mixing raw materials is not ideal for mass-production methods because it can be costly. In addition, the physical and chemical properties are difficult to combine in the traditional methods.

With various materials at hand, you can achieve anything you have in mind.

#8 Better Quality

If you bake a cake and follow the recipe accurately, you will end up with a delicious cake. However, if you are new to baking, your cake may taste amazing, but it may have unwanted air bubbles, a different texture, and thickness.

Getting rid of the mass manufacturing faults will produce better quality products. While this may not sound profitable to manufacturers, it’s a major advantage to the end consumer.

#9 Environmentally Friendly

For instance, aircraft makers junked 90 percent of their materials because it’s no longer useful. With additive manufacturing used in 3D printing, it will use lesser energy and waste will be reduced to a minimum.

The 3D printed object is 60 percent lighter but solid and sturdy. The lesser the waste, the lower the impact on the environment.

#10 Accessibility

More and more people are getting access to 3D printing. In fact, there are 3D printing pens that can produce the same results as that of the 3D printer, only which, the user will have to maneuver the nozzle with his own hands.

With this progress, many will be able to create the product they need, when they need it and wherever they are. This scenario can surely shake up the current consumerism ideology.

Conclusion

This page should answer your question “what can I print with a 3d printer?” 3D printing is so powerful that it can create almost anything. From food, clothing, houses to organ tissues and cells.

Moreover, 3D printing technology is better, cheaper, faster, more flexible, more sustainable and more environment-friendly. You can expect this technology to be more popular in the coming years.

Can you imagine the world where everything is possible? We are closer to that world with 3D printing.

What is 3D Printing?

3D printing, also called additive manufacturing is a process of making three-dimensional solid objects using a digital file. Prior to coming up with the 3D object, it has to go through additive processes.

In the additive process, the object is created using several layers of material. Each of this layer is essential in the formation of the 3D object.

The layers are the thinly sliced horizontal cross-section of the object. So, basically, it’s just piling up layer by layer.

History of 3D Printing

Charles Hull, co-founder of 3D Systems, initiated the development of 3D printing. He invented stereolithography, a process that produced a tangible 3D object from digital data. This technology is used to create a 3D model from a picture where users can test a design before investing in a larger version.

3D Printing Milestones

1992 – 3D Systems produced the first SLA (stereolithographic apparatus) machine. The process involved a UV laser solidifying photopolymer, a liquid with viscosity and color similar to honey.

It made three-dimensional objects, layer by layer. The first machine was imperfect, but it was promising because it can manufacture highly complex parts.

1999 – 3D printing contributed new advances in medicine through engineered organs. The scientists at the Wake Forest Institute for Regenerative Medicine engineered the first lab-grown organ using a 3D printer.

They used a synthetic scaffold coated with the patient’s own cells. The process had little to no risk of rejection because it is made with the patient’s cell. This paved the way to developing new strategies for engineering organs.

2002 – The scientists created a mini-functional kidney that was capable of filtering blood and producing diluted urine in an animal. This development had led to bigger goals of producing organs and tissues using 3D printing technology.

2005 – Dr. Adrian Bowyer founded RepRap, an open-source initiative to create a 3D printer that can print most of its own components. The goal of the project was to distribute cheap RepRap units so individuals can create products on their own.

2006 – The first SLS (selective laser sintering) machine was produced. SLS machine uses a laser to fuse materials and build 3D products.This development paved the way for mass customization and on-demand manufacturing of industrial parts and prostheses.

Different Technologies in 3D Printing

Stereolithography (SLA)

Stereolithography (SLA) – This 3D printing method is the first method in the history of 3D printing. It is the oldest but is still being used today.

Most printing techniques use a CAD file to process the object, which is then converted to a format that a printing machine can understand. In this technology, a software processes the CAD model and generates the STL file that contains the information for each layer.

The whole process includes a consequent printing layer by layer. There could be up to ten layers per each millimeter. Once all layers are printed, the object needs to be rinsed with a solvent and placed in an ultraviolet oven to finish the process.

Digital Light Processing (DLP)

DLP is similar to stereolithography. Larry Hornbeck of Texas Instruments created this technology in 1987. This is popular in the production of projectors and is applicable for cell phones and 3D printing as well.

DLP technology uses digital micromirrors laid out on a semiconductor chip. Although DLP and SLA both work with photopolymers, they use different sources of light. DLP uses more conventional sources like arc lamps.

Moreover, DLP uses a liquid crystal display panel that is being applied to the whole surface of the building material. The material for printing is a liquid plastic resin placed in the transparent resin container. The resin quickly hardens when exposed to a large amount of light.

The printing speed is fast. Compared to SL, DLP produces more robust 3D objects with excellent resolution. It also uses lesser material that results in lower cost and reduced waste.

Fused deposition modeling (FDM)

FDM is the most popular technology in 3D printing. It allows you to print concept models and final end-use products with engineering-grade thermoplastic.

FDM is the only 3D printing technology that builds parts with production-grade thermoplastics that produces excellent mechanical, thermal and chemical qualities making it very useful and appealing to manufacturers and engineers.

FDM Technology builds a 3D object layer by layer from the bottom to the top by heating and extruding thermoplastic filament. The whole process is similar to stereolithography but slower.

This technology uses a special software to cut the CAD model into layers and calculate the way the printer extruder will build each layer. The printer will heat the thermoplastic up to its melting point and extrudes throughout the nozzle onto the base to build platform along the calculated path.

A computer will translate the dimension of the object into X, Y and Z coordinates and control the nozzle and the base, so that it follows the calculated path during printing.

This technology is used in automobile companies like Hyundai and BMW and food companies including Nestle and Dial. FDM technology is simple to use, and it can build complex geometries and cavities. Moreover, it is environment-friendly.

Selective Laser Sintering (SLS)

This technology uses a laser as a power source to form 3D objects. Carl Deckard, a student of Texas University and his professor Joe Beaman discovered this technology in 1980. SLS has some resemblance with SLA but they differ in the material used.

SLS uses powdered material instead of liquid resin. In addition, SLS does not use any support structures because the object being printed is already surrounded by unsintered powder.

Similar to other technologies, SLS starts with the creation of the CAD file, which is then converted into a .stl format using special software.

This technology allows nylon, ceramics, glass and metals like aluminum, steel or silver. Due to its wide variety of materials, SLS is popular for customizing 3D objects.

Selective laser melting (SLM)

This technique also uses CAD data and builds a 3D object through a high-power laser beamthat fuses and melts metallic powders. Several sources consider SLM as a subcategory of SLS but the two technologies have major differences.

The SLM processes fully melt the metal into solid 3D parts, unlike selective laser sintering. SLM also uses a CAD file, and special software to slice the CAD file into 2D layers.

When the file is loaded, the printing machine’s software will assign parameters and values for construction of the path.

The fine metal powder is evenly distributed onto the plate and a high laser energy will be directed into it to fuse each slice of 2D layer image. The energy is so strong that the metal powder melts and forms a solid object.

The process repeats for the next layer until the product is complete. SLM uses the following metals: stainless steel, titanium, cobalt chrome, and aluminum.

SLM is widely used in objects with complex geometries and structures with thin walls and hidden voids or channels.

This technology is used in aerospace manufacturing and orthopedics but it is not widely distributed among households.

Electronic Beam Melting (EBM)

This technology is another type of additive manufacturing for metal parts. It is similar to SLM as it also uses a powder bed fusion technique.

However, instead of using a high-power laser beam as its power source, it uses an electron beam. This is the main difference between the two, the rest of the process is the same.

EBM is slow and expensive compared to SLM. Also, the materials are limited. Most materials used are commercially pure titanium, Inconel 718 and Inconel 625. This technology focuses on medical implants and aerospace area.

Laminated Object Manufacturing (LOM)

Helisys Inc., a California-based company, develops this rapid prototyping system. During LOM process layers of adhesive-coated paper, plastic or metal laminates are fused together through heat and pressure.

Then, they are cut into shapes with computer-controlled laser or knife. The post-processing of 3D printed parts includes machining and drilling.

This technology also starts with a CAD file that is later converted into an STL or 3DS format. LOM printers use continuous sheet coated with adhesive and laid down cross substrate with a heated roller.

The heated roller is passed over the material sheets on substrate melts the adhesive and the laser or knife will then trace it to its desired dimension.

When the layer is finished, it will move down and a new sheet will be processed. The process is repeated until the 3D object is fully printed.

LOM is not that popular but it is one of the most affordable and fastest 3D printing technology. Moreover, printing is low cost because it does not use expensive materials.

Binder Jetting (BJ) Technology

The Massachusetts Institute of Technology invented BJ 3D printing. This is called by many other names such as:

• Powder bed printing
• Inkjet 3D printing
• Drop-on-powder
• Binder Jetting (BJ) – the most popular name.

BJ uses two types of materials a powder-based material and a bonding agent. The “bonding” agent acts as a strong adhesive that holds the powder layers together.

The printer nozzles extrude the binder in a liquid form similar to a regular 2D inkjet printer. After completing each layer, the build plate lowers slightly to allow for the next one. The process is repeated until the process is finished.

This 3D printing technology doesn’t give you high-resolution or overly rugged 3D objects. But it allows you to print parts in full color.

BJ is being used in aerospace, automotive and medical industries.

Material Jetting (MJ) Polyjet and Wax Casting Technology 

Material Jetting is also called wax casting. Unlike the other 3D printing technologies no one invented MJ.

This is considered more of a technique than an actual printing process. Jewelers have used this for centuries to produce high-quality customizable jewelry.

MJ starts with a 3D model (CAD file). Once this is uploaded to the printer, the system does all the rest.

The printer adds molted (heated) wax to the aluminum build platform in controlled layers. It will be sweep evenly across the build area.

As soon as it lands on the build plate, it begins to cool down and solidify (UV light helps to cure the layers). As the 3D parts build-up, a gel-like material helps support it.

Once it’s done, you can easily remove the object by hand or by using powerful water jets. Once the part is complete, it can be used right away. No need for further post-curing.

This produce objects with good resolution. Polyjet MJ 3D printers are used mainly in the dental and jewelry industries.
