3D Printer Buying Review Guide

Choosing a high-quality 3D printer can be a daunting task especially that there are tons of manufacturers claiming to deliver the best 3D printers on the market.

There are tons of DIY and kits that you can find online and it can be confusing what to get. I suggest that you consider this buying guideline first to find the best quality 3d printer.

Price – 3D printer cost differs. There are affordable and expensive machines but its price is determined by its features and specifications. When it comes to price, you better consider your budget and the type of printer you need. You might also need to consider the timing when a brand offers a discount.

Materials – Determining your intended application and the material characteristic is a significant factor in selecting a 3D printer. For instance, for concept modeling applications, the physical properties of the object are not very significant. However, materials for rapid manufacturing applications need to be castable or should be high-temperature resistant. Thus, consider your application whether it is for concept models, verification models, pre-production applications or digital model or manufacturing.

The two most common materials are Poly Lactic Acid (PLA) and Acrylonitrile Butadiene Styrene (ABS) but there are also ceramic, wooden, bronze and more. There are 3D printers that combine multiple technologies and can accommodate a number of materials, which adds to its flexibility.

Print Speed – This refers to the time required for printing a finite distance in the z-direction because 3D printers build a component layer by layer. High print speed is always an advantage especially for concept modeling because it will allow you to quickly make an alternative of your digital 3D model for comparison and improve it in a short span of time.

Part Cost – This performance attribute is determined by how much total material a 3D printer consumes to print a given set of parts. You can find the lowest part cost with powder-based 3D printing technologies like gypsum powder, where the unused powder is recycled and re-used.

Some popular 3D printers blend expensive build material into support material during the 3D printing process to create support but this will increase your total cost of materials consumed. In addition, this produces more in-process material waste. So when choosing a 3D printer, learn how it operates before purchasing it or you might spend more when using it.

Detail Resolution – This 3D printer attribute is usually stated in dots per inch (DPI), Z-layer thickness, pixel size, beam spot size, and bead diameter. You can double-check the resolution by visual inspection. Use a digital microscope and examine the edge, corner definition, and texture. If you need a 3D printer for verification testing, you need one with a great detail resolution because the printed parts need to follow the design accurately.

Accuracy – This attribute refers to the quality of the printed parts. Accuracy is critical for printing-specific measurement test parts and in producing objects with solid print quality.

The process allows you to produce each part additively and you may have to deal with material shrinkage, which needs to be compensated to produce accurate results. Power-based 3D printers have the least shrink distortion and are generally accurate. Meanwhile, plastic 3D printing technologies that use heat, UV light or both are subject to more variables that can reduce its accuracy.

Now that you know the important details that you need to learn, it’s time to check the different 3D printer reviews to see what machine suits you best.

The 3D printer is a great investment especially for engineers and designers because it enables you to produce any 3d design you have in mind be it a small organizer, clothes for your fashion collection, a household tool, a vehicle or a building.

Where Can I Buy A 3D Printer

For those who are asking themselves this question “where can I find a 3d printer” or this “where can I get a 3d printer” the best place to buy 3D printer is by visiting the website of the brands, we mentioned above because they have a 3D printer for home that is for sale. They have customer service that is expert on their product, so you can guarantee their after-sales support.

You can also search for “3d printers for sale near me” to find 3D printers sellers near you. The good thing about buying the machine near you is that you can test it before your purchase.

You can also visit e-commerce corporations like eBay and Amazon as some retailers offer 3D printer kits on the site. The good thing about buying from these sites is that you can read a lot of reviews about the product prior to buying one, so you will be guided accordingly as to what particular model to purchase.

What is a 3D Printer?

The old printers only print an object in two dimensions. You can see and touch it but you can’t feel its edges and curves. Two-dimensional objects are devoid of texture, weight, and volume but 3D printers have it.

On the other hand, 3D printing machines produce things that you can touch and feel. It produces objects with texture, volume, and weight. More importantly, they are usable.

3D printing, on the other hand, is an additive manufacturing process that helps you realize a three-dimensional object from a two-dimensional digital design. It builds the three-dimensional physical object by dividing the digital model into layers.

The 3D printing machine prints each layer and it piles up. As a new layer is added to the object it gains weight and volume. For this reason, the term additive manufacturing is also used to refer to 3D printing.

If you can’t afford a 3D printing machine, you can start 3D printing with 3D drawing pens.

Types of 3D Printers

There are two main types of 3D printers for additive manufacturing: the small and large.

Small 3D Printer – This type of printer is usually used to print small objects like mini figurines, cartoon characters, tools, utensils, shoes, gadget accessories, keychains, and more. These devices only have a small printing area and can even be placed on your desktop. Learn more about portable 3D printers here.

Large 3D Printer – This machine can print large objects like vehicle parts, music instruments, furniture, and even a house. Learn more about big 3D printing machines here.

Significance of a 3D Printer

If you are a businessman who wants to present a new project to your potential client, what’s the best thing to do than bring a prototype? Of course, you can present papers but bringing a model that your client can touch and feel is different. It is better, more convincing and effective.

Initially, if you want to build a model or prototype you have to carve it or sculpt it. The process is tedious and may take days. This is the reason why the overall process tends to be expensive. You have to pay for the raw material and labor, which could take days, weeks or months.

On the other hand, a 3D printer has the power to speed up the process and help you cut costs. With a 3D printer, you don’t need to wait for weeks to finish your prototype, deal with your workers’ inefficiency and pay for labor.

Getting a 3D printer saves you time and money. In addition, it keeps you from worries and gives you peace of mind.

3D Printer Parts

Aside from understanding the additive manufacturing processes, you have to be familiar with the printing machine’s main components to better understand how it operates.

By familiarizing a 3D printing machine, you will also be able to:

• Achieve better quality, strength and speed
• Easily maintain it
• Choose the right one that suits your needs
• Upgrade and modify a particular part for specific applications

Here are the different parts of a 3D printer that you need to know.

Z Resolution – Layer Thickness
This refers to the minimum thickness of a layer printed down in a single pass. A high-resolution 3d printer has a small number of layer thickness. The lesser the numeral, the smoother and more detailed the print is, but the slower the process.

Build Area
This is the maximum size of an object that you can create with the 3D printer. It is measured in XYZ dimension. If your 3D printing jobs are complicated and huge, you can split it into smaller parts and combine afterward.

Filament Diameter
The most used plastic filament diameters are 1.75mm and 3mm. But this may depend on each individual’s preference.

Hot End
This is one of the most important parts of the 3D printer. It is where the plastic is melted and extruded in little tiny layers.
This is available in Peek Based Hot Ends with a maximum temperature of 230°C and All Metal Hot Ends with a maximum temperature of 320°C.

Extruder
This is the part that feeds the filament to the hot end. There are two types of extruders: Direct and Bowden.

Direct is when the filament is fed directly to the Hot End from the motor spindle. It is mounted on top of the hot end that allows for finer control over the extrusion. It is also easier to work with.

Bowden is when the filament is fed from a certain distance to the Hot End (the extruder is physically separated from the hot end). Due to the distance, the filament has to travel and it’s oozing more. Thus, this requires better extrusion and retraction calibration.

Cooling Fan
This is a must-have in every because the process requires active cooling. It can dramatically improve overhanging features, crisp the sharp edges and result in good bridging capabilities.

Cooling fans are designed differently. There are 3D printers that use 25mm, others 40mm. Some are designed to blow at the mid hot end area while others focused at the tip of the nozzle. There are also fans with different shaped ducts.

Heated Bed
This is required for all high-temperature extrusion filaments like ABS, HIPS, Polycarbonate and Nylon. This is designed to keep the plastic warm during the printing process and prevent it from warping.

In addition, this ensures better adhesion between the layers that results in better structural integrity of the printed parts. The temperature in this area usually ranges between 40°C to 110°C.

Printed Bed
This is the surface of the 3D printer where a print head lays down the material after 3D printing. This needs to be level and flat.

LCD Display
This allows you to control the printer without the need for a computer or 3D printing software like Cura. It just needs an SD card to read the G-code instructions. The display also allows for more efficient space usage and it frees up your computer for other tasks.

Multiple Extruders
Multiple extruders allow you to print in multiple colors or materials simultaneously by assigning each extruder specific material. There are printers that can be upgraded from single to multiple extruders.

The biggest benefit of this is that you can set the support structures with a different material that can be dissolved in water or other types of solvent.

How Does a 3D Printer Work?

How does a 3D printing process work? As mentioned, good 3D printers produce a three-dimensional object. However, it does so in a different way using the additive manufacturing process.

For instance, if you do a miniature of your dream house, you will need to construct it similar to how you build a real home but with different materials.

For instance, you make replicas of the walls by cutting cards and gluing them together. You make replicas of the window, paint it if necessary to follow your design and attach it to the structure you build.

While seeing a machine operating in this manner could be impressive, a 3D printer has a different approach using additive manufacturing. This is similar to an inkjet printer that is operated from a computer. However, it uses different materials in printing an object. Instead of using ink, a 3D printing machine uses layers of molten plastic or powder and fuses them together with an adhesive or ultraviolet light.

A 3D printer does not cut objects and glue it together to form a prototype instead, it uses the additive manufacturing process. It builds the printed parts by joining the material layer by layer from a CAD file.

The 3D printing process divides the whole object into thousands of tiny slices and makes it from the bottom-up repeatedly printing over the same area in a method popularly known as fused depositional modeling (FDM), a popular type of 3D rapid prototyping.

Each layer in additive manufacturing processes can be very complex but a 3D printer can execute it. It creates moving parts like hinges and wheels. You could also print a ready-to-assemble bike, handlebars, frame, wheels, brakes, pedals and chains without any tools.

The 3D printer works automatically and creates the digital model in just a matter of hours by turning a 3D CAD drawing into thousands of two-dimensional and cross-sectional layers and then sit one layer on top of another, this process is repeated until the object is done.
