- About us
The technology uses selective hardening of a part of a photopolymer bath, using a UV radiation source located below an LCD display which shields the exposed layer to create a desired shape. The hardening process goes layer-by-layer. This printing method is used for very detailed designs, with a very high surface quality and dimensional precision which is higher than that of FDM technologies.
A DLP based printer can print products with high-quality surface, high level of detail and minimum manufacturing waste. As one of a few printers, it can print from transparent (but matte) materials.
