Manufacturing method of three-dimensional object and consumable assembly

Abstract

The embodiment of the invention provides a manufacturing method of a three-dimensional object and a consumable assembly, and relates to the technical field of 3D printing. The manufacturing method of the three-dimensional object provided by the embodiment of the invention comprises the following steps: carrying out photocuring 3D printing, so that a photocurable material forms the three-dimensional object on a forming platform, carrying out post-treatment on the three-dimensional object, and separating the three-dimensional object from the forming platform, so that the manufacturing of the three-dimensional object is realized. And meanwhile, the forming platform used in the manufacturing method is a disposable piece, so that the forming platform can be directly abandoned after the three-dimensional object is manufactured, the forming platform does not need to be cleaned and maintained, and the use is more convenient. And the service life of the forming platform does not need to be judged, and the problems that the printing precision becomes poor and even printing fails due to the fact that the surface of the forming platform is damaged are solved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a method for manufacturing a three-dimensional object and a consumable component. Background technique [0002] At present, the light-curing 3D printer includes a forming platform, a material tray and a light source. The light source projects light to the light-transmitting material tray at the bottom, so that the photocurable material between the forming platform and the bottom of the material tray undergoes a polymerization reaction to obtain a cured sheet. The material is bonded to the forming platform, and the forming platform is kept away from the bottom of the tray, and at the same time, the light source is projected to the bottom of the tray intermittently or uninterruptedly, and solidified layer by layer. The stacked cured sheets are finally formed into a three-dimensional solid print. [0003] After the printing is completed, the user needs to shovel the printed part...

AI Technical Summary

Problems solved by technology

[0003] After the printing is completed, the user needs to shovel the printed part off the forming platform. Since the forming platform is a consumable, as the number of printings increases during the 3D printing process, the flatness and roughness of the forming surface of the forming platform may not be sufficient for printing. demand, which brings the risk of poor printing accuracy or printing failure

Therefore, it is necessary to clean and maintain the forming platform after each printing, and replace the forming platform after a certain number of uses. However, it is obviously difficult for users to judge the service life of the forming platform and bear the risk of printing failure.
