CAD stands for computer aided design. It is a series of design tools that many professionals in the industry use to create and edit 3D models of products and structures. CAD systems automate thousands of complex geometrical calculations in the background, making the designer's job easier. Instead of doing pages of calculations by hand, CAD software...

The technology behind fused deposition modeling 3D printing is based on an innovative printer software program that separates a 3-D CAD model into individual slices and then converts it into machine code. This software then directs the print head to follow the path of the 3D CAD model and deposit layers of material on the build platform until the...

Fused deposition modeling (3D printing) is a process that prints objects by melting and solidifying a filament. It does so without the need for supports and other structures. It is a good choice for prototyping, but it is not recommended for high-quality parts. Here are some cons of FDM. Read on for more information. But before you start a 3D...
