3D printing liquid tank device, 3D printer and 3D printing method

Abstract

The invention discloses a 3D printing liquid tank device, a 3D printer and a 3D printing method. The device comprises a liquid tank assembly for containing a printing liquid, the liquid tank assemblyand a driving assembly are separately located on two opposite sides of a mounting plate, the liquid tank assembly is partially contained in the mounting plate, and the bottom of the liquid tank assembly is wholly transparent or transparent in position corresponding to curing light; the mounting plate is provided with a through hole for passing of the curing light at the position, corresponding tothe curing light, of the liquid tank assembly, and the output end of the driving assembly penetrates the mounting plate and is fixedly connected to the bottom of the liquid tank assembly; and the liquid tank assembly is driven by the driving assembly to perform reciprocating swing motion at a preset angle, a printing area, located in the liquid tank assembly, of a scraper assembly is in the rangeof radiation in a reciprocating swing process, so that the scraper assembly can scrape off a printing liquid located in the printing area in the reciprocating swing process in the printing area. Compared with the prior art, the printing liquid is flatter, and the printing efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printing liquid tank device, a 3D printer and a 3D printing method. Background technique [0002] At present, light-curing 3D printing is to hold a printing solution such as a liquid photosensitive resin in a liquid tank, and cure it layer by layer through photomechanical exposure, and finally generate a printing model. [0003] When printing a resin solution with a low viscosity, the printing solution has good fluidity and can be self-leveling, but when printing a relatively viscous resin solution, due to the poor fluidity of the viscous resin, it is difficult to achieve self-leveling, which affects printing speed and Printing accuracy, even printing failure may occur; [0004] To solve this problem, there is a patented design of a rotatable liquid tank and a scraper mechanism to scrape the viscous printing solution, but both the liquid tank and the printing area rotat...

Problems solved by technology

[0005] The object of the present invention is to provide a 3D printing liquid tank device, a 3D printer and a 3D printing method for the technical problems existing in the prior art. The liquid tank and printing area in the middle rotate around, which reduces a part of ineffective rotation time, improves printing efficiency, and solves the problems of too long rotation time and low printing efficiency in the prior art
