What is Vat Photopolymerization 3D Printing?

Posted on Apr 02, 2020 by Cullen Hikene

Vat photopolymerization is a 3D Printing process that involves selectively curing photosensitive resin in a vat using focused light. Vat Photopolymerization is an outstanding solution for parts requiring a smooth surface finish, tight tolerances, and low-to-moderate functional requirements.

What are the Different Types of Vat Photopolymerization?

  1. Vat Photopolymerization (Resin, UV Laser)
  2. Vat Photopolymerization (Resin, Projection)
