As 3Dprinting has grown in popularity so too has the language, that is why we have created this 3D printing dictionary to help you navigate the 3D world.

Imagine traveling to a foreign country and trying to communicate with the locals in their language.  3D printing is much the same, if you don’t know the language it is going to be hard to understand the subject.

We hope it helps.
