Digital Light Processing (DLP)
DLP follows a near identical method of producing parts when compared to SLA. The main difference is that DLP uses a digital light projector screen to flash a single image of each layer all at once. Because the projector is a digital screen, the image of each layer is composed of square pixels, resulting in a layer formed from small rectangular bricks called voxels. DLP can achieve faster print times compared to SLA for some parts, as each entire layer is exposed all at once, rather than tracing the cross-sectional area with a laser.

DLP Technology is the best for:
One-off small and very intricate parts
Quickly printing large parts without much detail
DLP (Projector) technology enables fast accurate 3D scanning & printing for a variety of applications
DLP technology enables fast and accurate 3D scans using structured light for industrial, medical and security applications. Fast, programmable pattern rates acquire 3D scan data in real time delivering high quality, high bit depth patterns for accurate scans with resolutions as low as a few micros. You can develop handheld, portable systems.
