How Does a 3D Printer Work?

How Does a 3D Printer Work

In order to use a 3D printer, you will need to design the object on your computer, connect it to the printer, and then press print. The process is similar to that of making sliced bread. A 3D printer glues individual slices together just like a baker makes a whole loaf. But a 3D printer has more options. You can print out a whole object if you like.

Computer-aided design (CAD)

Computer-aided design (CAD)

The latest versions of CAD software are cloud-based and allow users to share files and collaborate across workstations. These software programs also incorporate artificial intelligence (AI), which allows users to test mechanical aspects in hours instead of days. CAD software is also becoming increasingly sophisticated, and generative design makes the computer a co-creator with the user. It makes use of artificial intelligence to suggest shapes and surfaces that are optimal for a particular application. These advances in CAD software also allow designers and engineers to make rapid prototypes of their ideas. These benefits are widely recognized by the industry, and the use of 3D printers in manufacturing has expanded rapidly.

Selective Laser Melting (SLM)

SLM offers tremendous geometric freedom and is often a good choice for bionic and lightweight construction projects. Another advantage of SLM is assembly consolidation, wherein individual assemblies can be printed in a single piece, reducing labor and material costs. SLM also can improve component properties, making the printed parts dense and nearly pore-free. Read on to learn how SLM can benefit you and your projects.

Fused Deposition Model (FDM)

A fused deposition model, or FDM, for best 3d printer, creates objects using layers of material. The material is melted just past the glass transition temperature, and then extruded in a pattern. The process builds the object layer by layer until the desired shape is reached. This type of technology has several advantages, including a low cost and a variety of material choices.

Vat Polymerization (SLA)

Vat Polymerization (SLA)

SLA processes emit high levels of VOCs, but not as much as FFF. While the average FFF 3D printer emits a maximum of 1 mg/h of VOCs, the total emissions from SLA 3D printers are considerably higher than the average. The print, wash, and cure processes of SLA 3D printers produce a complex mixture of chemical compounds that contribute to the high VOC emissions.


Multi-material 3D printing is a method of additive manufacturing in which multiple materials are used simultaneously to build objects. It is similar to single-material additive manufacturing, and is possible through a variety of methods such as SLA, FFF, and Inkjet 3D printing. Here are some benefits of multi-material 3D printing. They can help you design more complex items, and give you better control over the process.

George Martin Administrator

George Martin is a business consultant born in New York City. He is very talented and never got 2nd except for the 1st place in school and college life. His dream was to own a business firm. So, he never applied for a job. In 2009, he opened a consultanting firm. He completed his graduation in International Business and Finance at Fordham University. Traveling is his favorite hobby and never missed to make a trip with his family to a new place every month.
