DLP 3D printer with adjustable forming base face

Abstract

The invention discloses a DLP 3D printer with an adjustable forming base face. A sliding block guide rail system is fixed between the top face of a metal plate frame and a support plate through a screw. A sliding block can move up and down on a sliding rail. An X-Z direction rotary disc is fixed to the sliding block through a screw, and rotation of a forming base plate in the X-Z direction can be controlled. A Y-Z direction rotary disc is fixed to the X-Z direction rotary disc through a screw, and rotation of the forming base plate in the Y-Z direction can be controlled. The forming base face is fixed to the Y-Z direction rotary disc through a screw. The support plate is fixed in the middle of the metal plate frame through welding and is parallel to the upper face and the lower face of the metal plate frame. A light-out system and a plane mirror are fixed to the bottom face of the metal plate frame, and a placing device can make a projective plane formed by the light-out system be projected in a resin groove after being reflected through the plane mirror. Through the device, the DLP 3D printer with the adjustable forming base face can be completed.

Description

technical field [0001] The invention belongs to the field of 3D and relates to a DLP 3D printing device with an adjustable base surface. Background technique [0002] At present, with the gradual development of 3D printing technology, various 3D printers have entered many fields such as military industry and medical treatment. As a conventional 3D printer, DLP 3D printer has the advantages of fast printing speed and high molding quality. DLP 3D printer prints The accuracy of the parts largely depends on the parallelism between the molding base surface and the bottom surface of the resin tank. Generally, after the DLP 3D printer leaves the factory, the molding base surface and the bottom surface of the resin tank have a good parallelism. During use, due to wear, deformation, etc. The reason is that the parallelism between the molding base surface and the bottom surface of the resin tank is reduced, which affects the printing accuracy and is inconvenient to use. Therefore, by ...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the existing problem of DLP 3D printers that the printing accuracy cannot be adjusted due to the non-adjustable parallelism between the molding base surface and the bottom surface of the resin tank, the present invention provides a DLP 3D printer with an adjustable molding base surface. The molding base surface of the 3D printer can be adjusted Adjustment, so as to ensure a good parallelism between the molding base surface and the bottom surface of the resin tank, and has broad application prospects
