Direct Light Processing: DLP

This lecture covers the principles and examples of Digital Light Processing (DLP) in comparison to Stereolithography (SLA) and Polyjet technologies. It explains the DLP process, consolidation mechanism, feeding of photoresist, curing, and construction plate. The lecture also discusses the technical data of DLP, including the use of different materials, applications, equipment specifications, and performance metrics. Examples of parts produced using DLP technology are presented, such as lost patterns for investment casting and various types of resists. The characteristics and providers of DLP systems are outlined, highlighting advantages like price and simplicity, as well as disadvantages in precision and productivity when compared to SLA.
