Welcome to PADT’s online 3D Printing Glossary. A place to find definitions for the terms used in the Additive Manufacturing industry.
It is by no means authoritative nor complete, but we hope you find it helpful. It is our take on the words used in the industry, based on our activity in that industry since the mid-1990s. We hope it will serve as a starting point for a larger and more comprehensive glossary as time passes. To that end, If you have a term you would like to see added, or a suggestion for a change to one of our definitions, please share your suggestions here.
