The invention provides a scraping knife assembly. The scraping knife assembly comprises a double-edge scraping knife, a moving part, and a mounting part for mounting the double-edge scraping knife, wherein the double-edge scraping knife is mounted at the mounting part and is arranged at the upper part of a printing plane; the mounting part is connected to the moving part, and the moving part drives the mounting part to move so as to drive the double-edge scraping knife to move and uniformly spread printing slurry on the printing plane. The invention also provides a printing device. According to the technical scheme provided in the embodiment, the scraping knife assembly is capable of directly uniformly horizontally spreading the printing slurry on the printing plane, so that the printing efficiency and the printing accuracy can be improved; and moreover, residual printing slurry can be concentrated into a cavity of the double-edge scraping knife, and thus the utilization rate of the printing slurry is increased.
Description
technical field [0001] The invention relates to the technical field of 3D printing, in particular to a scraper assembly and printing equipment. Background technique [0002] 3D (Three-Dimensional) printing, also known as three-dimensional printing, is a machine that uses cumulative manufacturing technology (that is, rapid prototyping technology). Created in layers. [0003] At present, when conventional 3D printing equipment prints high-viscosity printing paste, the scraper structure in the equipment does not have the function of directly flattening the surface of the printing paste, and its printing accuracy is low; and conventional During the printing process of advanced 3D printing equipment, the excess printing paste is directly pushed into the recycling box, and the utilization rate of the printing paste is low. Contents of the invention [0004] The main purpose of the present invention is to provide a scraper assembly and printing equipment, aiming to solve the pr...
