Digital Light Processing (DLP) 3D printer uses photopolymerization to create 3D components. 3D printing technologies based on DLP are frequently used for fabricating complex objects without tooling and machining. In this paper, concerning some aspects of the Digital Light Processing technology such as the brief introduction, development history, some advantages, and practical applications in various fields is presented. The authors analyze existing devices, these device' design embodiment decisions is chosen based on the selection matrix. The main content of this paper is that we present the principle, construction as well as analyzing and choose the best design for a 3D Rapid Prototyping machine using Digital Light Processing technology. We also implement some results of designed parts as well as the manufactured machine.
