Selective Light-Engine

Selective Light-Engine

Antech Solutions developed a light-engine that is based on a transparent LCD (Liquid Crystal Display) which can be used to selectively cure photosensitive resin in 3D printing technologies. Secondly this technology can be applied to produce PCB’s (Printed Circuit Boards). 

With experience in 3D printing Antech Solutions started this development as an alternative for DLP and laser based light sources applied in 3D printing technologies. Some major benefits compared to existing DLP and Laser solutions are:
 ⁃ Build in dimensions (close to projection area) 
 ⁃ Uniform light distribution within projection area
 ⁃ No optic distortion
 ⁃ Fixed pixel size
 ⁃ Low cost price

Antech Solutions did research by testing many different LCD’s which are available on the market in combination with a custom made light source in different color wavelengths. Finally a functional prototype was realized in-house.
