How to Choose a 3D Printer: Simplify Your Decision-Making Process

 Choosing a 3D printer can be a challenging task, especially for beginners who are new to the world of 3D printing. Before you make a decision, there are several factors to think about. Build volume, user interface, material compatibility, and printer speed are among the many things to take into account.

These factors can affect the performance, quality, and functionality of the 3D printer and the 3D prints. Therefore, it is important to know what to look for when selecting a suitable 3D printer.

How do 3D printers work?

3D printing is also known as additive manufacturing. The 3D printing technology helps create physical objects from digital models by depositing more layers of material on top of each other. Unlike traditional manufacturing methods, additive manufacturing requires no tools or molds to create and print objects.

The 3D printing process enables the fabrication of complex geometries and custom designs. It works with precision and efficiency. Thus, completing a project at a lower cost means less material waste. 3D printing is a great tool for prototyping, production, and customization. It allows for the creation of functional and durable parts. 

There are different types of 3D printing methods and technologies. However, all types of 3D printing technologies follow the same basic steps. 

First, a 3D model is designed using CAD software or scanned from an existing object. Second, the 3D model is sliced into thin layers by slicing software, which also generates instructions for the 3D printers on how to move and extrude the material. 

Third, the 3D printer heats the material, usually a plastic filament or a resin, and pushes it through a nozzle or a laser beam to form each layer on a platform or a bed. The printer repeats the process until the entire object is completed.

The revolutionary technology of 3D printing finds its application in many industries, including engineering, architecture, medicine, art, and education.

Types of 3D Printing Process

There are several types of 3D printing technologies, and each of the printing technologies involves distinct processes and materials. Different printing technologies have their pros and cons. When choosing one type of 3D printing over the other, it is crucial to think along the lines of your project type and personal preferences. 

Fused Deposition Modeling (FDM)

FDM is one of the most commonly used 3D printing methods due to its affordability. It works by melting a plastic filament and extruding it through a nozzle to form layers of the object. FDM is great for making durable and functional parts. High-end industrial FDM printers have greatly increased in precision as compared to when the technology was new.

Stereolithography (SLA)

SLA is one of the oldest and most accurate types of 3D printing. It works by curing a photosensitive liquid resin with a UV laser to form layers of the object. With SLA you can make high-quality detailed parts, but it requires post-processing and support removal. The resin used can be toxic and expensive.

Selective Laser Sintering (SLS)

This type of 3D printing uses a laser to fuse powdered materials into solid layers of the object. SLS is a good option for making strong and complex parts. It has low color options and poor resolution. The use of powder as a material can be wasteful and messy.

Direct Metal Laser Sintering (DMLS)

DMLS uses a laser to fuse metal powder into solid layers. It can be used to make metal parts with high strength and durability. However, it is expensive and requires specialized equipment and safety measures.

Electron Beam Melting (EBM)

Similar to DMLS, EBM involves the use of an electron beam to melt metal powder to form layers. However, EBM uses a vacuum chamber and high temperatures. The EBM technology is suitable for creating metal parts with high density and resistance. It is also costly and requires specialized equipment and safety measures.

Material Jetting

In material jetting, a printhead deposits droplets of materials onto a build platform to form layers. Types of material used include wax, metal, or photopolymer. Material jetting is useful for producing composite and full-color parts. However, it is a slow and expensive method and the materials can be brittle and unstable.

Binder Jetting

Binder jetting involves spraying a binder onto a layer of powdered materials to bind them together. Binder jetting binds materials, including metal, ceramic, or sand. It is suitable for creating large and complex prints. Although it requires post-processing and sintering, the parts created with binder jetting can be weak and porous.

Build Volume

The build volume is the maximum size of the objects you can print with a 3D printer. When considering the build volume, you should think about the kind of objects you want to print.

 If you plan to print large or complex objects, including sculptures, models, or props, you may require a large print volume 3D printer. However, a small build volume is sufficient if you only print small or simple objects, such as jewelry, toys, or parts.

Print Quality

The print quality is one of the most crucial factors to be considered. It involves the level of detail, accuracy, and smoothness of the 3D prints. The high-quality prints depend on several parameters, including resolution, accuracy, and finish.

The resolution for 3D printers is usually measured in microns, which is one-thousandth of a millimeter. A low micron value means high resolution and fine details. More detail can be printed by a 3D printer with a resolution of 25 microns than by one with a resolution of 50 microns.

The print accuracy is how closely the printed object matches the original 3D model. It is a result of the calibration, alignment, and stability of the 3D printer. A well-calibrated and stable 3D printer can produce accurate prints that match the dimensions and form of the 3D computer model.

The surface finish refers to the smoothness and appearance of the 3D print. A lower layer height, smaller nozzle size, and slower extrusion speed result in an object with a smooth finish. Post-processing can also reduce imperfections and visible layer lines.

Compare the specifications and samples of different 3D printers to arrive at a decision. Generally, 3D printers with excellent print quality are slower, more expensive, and more limited in the materials they use. However, these 3D printers produce more accurate and detailed prints, which can be essential for certain applications.

Compatible Material

Material compatibility refers to the range of materials a 3D printer can use for printing. Materials are the filaments or resins that are used to create 3D prints, and they come in various types. Every material possesses unique properties and characteristics.

3D printers support various types of materials, including thermoplastics, resins, metals, and composites. Consider the material you plan to use for your projects and how well the 3D printer can handle and print it. The availability and cost of the material to print is an overlooked aspect when selecting a 3D printer.

Pay attention to nozzle temperature settings, especially if you plan to work with special materials or ones with heat resistance properties. By carefully assessing these factors, you can minimize the risk of failed print and ensure consistent and high-quality output.

Print Speed

In 3D printing, print quality and speed are typically inversely related. The speed and efficiency of printers are the result of nozzle size, layer height, and the printer's settings. Generally, high quality prints result from low speed and are a time consuming process. 

One way to adjust the quality and speed of the print is by changing the nozzle size. A larger nozzle size can print faster but with less detail and accuracy. A smaller nozzle size can print slower but with higher detail and accuracy.

Additionally, changing the height of the layer influences print quality and speed. A lower height can print smoother and more realistic objects. However, this also leads to longer print times and more material consumption.

Print settings, including temperature and cooling settings, also determine how fast the printer works. These settings can affect how the material flows, adheres, and solidifies during the process. A higher temperature can print faster but with higher chances of warping.

Overall, you need to evaluate the printing speed of each printer and consider how it aligns with your project timelines and production needs. While faster 3D printers offer increased efficiency, they may also sacrifice print quality or require additional calibration and maintenance. The best way to save time is to optimize the model before printing.

Some 3D printers handle certain shapes and forms better than others. Thus, it is hard to compare the speed of different printers based on the specifications provided by manufacturers. You should judge the actual print speed by seeing the demonstration and sample output of the 3D printer.

User Experience

A user-friendly interface and an easy-to-use 3D printer are essential. It can make your whole experience of using a 3D printer effortless and productive. It allows you to focus on designing rather than struggling with complex settings.

Automatic bed leveling is one of the advanced features that automatically adjusts the distance between the print bed and the nozzle. This ensures that the first layer on the print bed is high quality and consistent. It allows you to save time. Since manually leveling the print bed can be a tedious task.

Having a touchscreen display can prove to be a great feature. It allows you to control and monitor the printer settings and status through a touch screen instead of buttons or dials. This ensures that the printer is very easy to use. Make sure that the touch screen of your 3D printer is high quality and has good reviews.

Wireless connectivity is one of the various features that make using a 3D printer much easier. It allows you to connect the printer to multiple devices through Wi-Fi or Bluetooth instead of using a USB cable or SD card.
