Digital Light Projector (DLP) 3D Printing Technology.

How it works

In this process objects are created by a 3D printer that uses a digital light projector (DLP) as the light source for curing photo-reactive polymers.

Simplified

 Advantage over Stereolithography (SLA)

DLP is generally considered to be faster than SLA, and here’s why:
With SLA, the laser has to individually cure the resin in a “point to point” technique. On the other hand, a DLP projector screen flashes an image of a layer all at once! Thus all points of a layer can be cured simultaneously. In this way, the print speed is increased in comparison to SLA since it takes less time to cure a single layer.
