We break it down in this article to unlock the science behind this technology so you can better understand the speedy 3D printing process that vat photopolymerization provides.
VAT photopolymerization is an industrial 3D printing process that uses light to form layers of solidified photopolymer resin. Photopolymerization is a process in which radiation or light energy triggers the formation of multiple chemical reactions that form a solid material. In the case of VAT photopolymerization, the 3D printer is filled with liquid photopolymer resin that is exposed to ultraviolet (UV) light. The light causes the molecular structure of the photopolymer resin to change, resulting in a solid cured layer in the desired shape. The 3D printer then moves down the build plate and another layer of photopolymer resin is exposed to UV light and the process is repeated until the entire object has been created. The end result is a 3D object with complex and intricate shapes and details.
