Abstract

The invention discloses a digital light procession (DLP) light curing 3D printing system. The system comprises a rack, a rack Za axis moving module, a light source system, a material groove, a formingtable Zb axis moving module and a forming table. The light source system comprises a light source, a curved mirror, optical quartz glass and a container. The light source, the curved mirror and the optical quartz glass are mounted in the container from top to bottom in sequence. The light source is an DLP light source containing a DMD chip and is located in the focal point of the curved mirror. The container is of a transparent material selected from optical quartz glass or polymethyl methacrylate or glass. The forming table is mounted on the forming table Zb axis moving module. Both the forming table and the forming table Zb axis moving module are mounted in the material groove. The bottom surface of the optical quartz glass is attached to the upper surface of a bottom plate of the container. By means of the DLP light curing 3D printing system, the problems that an existing light curing printing system is not high in light source utilization rate, small in forming size and low in printing speed are solved.

Description

Technical field [0001] The invention relates to a 3D printing technology, in particular to a DLP light curing 3D printing system. Background technique [0002] Rapid Prototyping Manufacturing (Rapid Prototyping Manufacturing) is also known as 3D printing technology. This technology manufactures entities in a layer-by-layer superimposed manner based on the three-dimensional model data of the object. It can overcome the special structural obstacles that cannot be achieved by traditional machining. , Realize the simplified production of arbitrarily complex structural parts. [0003] In 3D printing technology, light curing rapid prototyping technology is more common, which uses liquid photosensitive resin (UV) to polymerize under light, and illuminate the cross-sectional shape of the entity to be cured with a light source to make the liquid photosensitive resin layer by layer After curing and forming, it is accumulated and superimposed to finally form a solidified entity. [0004] DLP ...
