So What is 3D Printing?

3D printing is a term commonly used to describe the Additive Manufacturing (AM) process. There are a wide variety of materials and processes used to create 3D printed parts, each with their own specific benefits, but the basic premise is the same:

• A 3D solid model file is loaded into the printing machine’s software system.
• The software slices the geometry of the solid model into razor thin layers from one end to the other.


• Starting with the bottom layer, the printing machine traces the enclosed area of the cross section, curing the material into a hardened wafer as is goes.
• The machine then moves to the second layer that is now traced directly on top of the first one….and so on, and so on, until all of the layers are stacked on top of each other.

• The part has now been built layer by layer, and once removed from the machine is cleaned to remove any excess material. If no post processing finishing is required, then the part is ready to be used. It’s that simple.
