Digital Light Processing (DLP) 3D Printing

DLP (Digital Light Processing) is a 3D printing technology used to rapidly produce photopolymer parts. It's very similar to SLA with one significant difference -- where SLA machines use a laser that traces a layer, a DLP machine uses a projected light source to cure the entire layer at once.

Apart from FDM technology, the DLP 3D printing technology is also largely used for recreating medical models and even precision medical devices. Models like the bones, DNA study samples, dental models, muscle models, etc. And medical devices majorly for the hearing aid industry.

DLP 3D printers use a digital projector screen to flash an image of a layer across the entire platform, curing all points simultaneously. The light is reflected on a Digital Micromirror Device (DMD), a dynamic mask consisting of microscopic-size mirrors laid out in a matrix on a semiconductor chip.

About DLP 3D Printing Materials:

DLP 3D printers build up and shape materials from 3D software-generated data. Materials include metals, thermoplastic resins, and ultraviolet-curable resins.
