A projection technology that utilizes an array of microscopic mirrors arranged on a microchip to reflect a specific pattern of light through a lens. Each mirror represents a pixel, and light is projected onto the chip and a controller is used to flip each mirror to either deflect light for a given pixel through a lens or away from a lens. This provides a very sharp and accurate image.
The technology is common in projectors used in movie theaters, home theaters, and meeting rooms.
In additive manufacturing, Digital Light Processing projectors can be used instead of a laser to project ultraviolet light in a very accurate and precise pattern for vat photopolymerization and some binder jetting applications where a photopolymer is used as the binder.
Abbreviated as DLP.
