DLP vs LCD
A DLP printer has an optical projector, shining concentrated beams of light only where the resin needs to cure, producing incredibly crisp results without light leaks or blurry edges. DLP Projector can project a beam of higher uniformity, and the light uniformity of the forming surface is greater than 90%. With an LCD printer, a single big UV light shines through a screen that has either open or closed pixels. However, the light source is always on, which gives light leaks, even on dark pixels.
Durability
Thanks to DLP® technology, Anycubic Photon Ultra's light source system does not need to be replaced as often as an LCD 3D printer and has a life span of over 20,000 hours, 10 times longer than the 2,000 hours for LCD monochrome screens. Maintenance costs have been greatly reduced.
