Material tray tilting mechanism and DLP technology 3D printing device

Abstract

The invention discloses a material tray tilting mechanism and a DLP technology 3D printing device and relates to the technical field of 3D printing. By means of the material tray tilting mechanism andthe DLP technology 3D printing device, the technical problem that products or a material tray can easily be damaged during stripping off the products and the material tray in the prior art is solved.The material tray tilting mechanism comprises a material tray mounting plate and a driving device. The material tray mounting plate is provided with a connecting bracket and a through hole. The driving device is arranged on the connecting bracket and is used to drive one side or an angle of the material tray to move up and down in the through hole. Therefore, when the products and the material tray need to be stripped off after applying the material tray tilting mechanism to the DLP technology 3D printing device, one side or one corner of the material tray can be driven downward for a certaindistance by the material tray tilting mechanism before a lifting mechanism of a forming platform drives the forming platform to move vertically upward so that the effect of side stripping can be achieved and the damage of the products or the material tray can be avoided, so that the qualified rate of the products is improved, and the service life of the material tray is prolonged.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular, to a material tray tilting mechanism and a DLP technology 3D printing device. Background technique [0002] Digital Light Processing (abbreviation: DLP) technology was first developed by Texas Instruments, and mainly uses a projector to solidify photopolymer liquid layer by layer to create 3D printed objects. Because of its UV light projection, it can be quickly applied to the field of 3D printing, and it has become another new rapid prototyping technology. [0003] In the prior art, the downward projection type DLP technology 3D printer includes a frame, a material tray, a forming platform and a forming platform lifting mechanism for driving the forming platform to move up and down. In the actual use process, the product is formed on the material tray and the forming platform. Between the forming platforms, after each layer is cured, the product needs to be peeled off from th...
