Abstract

The present invention provides a coating scraper and a coating apparatus for photocuring rapid prototyping, the coating scraper is an integrated structure, and includes a mounting beam and a scraper body connected with the mounting beam, the scraper body is provided with a downwardly-opening long groove, and edges are arranged on two sides along the longitudinal direction of the long groove. The integrated-structure coating scraper is light in weight, easy to adjust and easy to assemble and reduces the cost.

Description

technical field [0001] The invention relates to the technical field of photocuring rapid prototyping, in particular to a coating scraper and a coating device for photocuring rapid prototyping. Background technique [0002] The coating device is an important part of the light-curing rapid prototyping system, and its processing accuracy and technology directly affect the quality of the whole machine. The purpose of coating is to ensure that a uniform thickness of liquid resin is obtained on the upper surface of the cured layer before scanning. If the thickness is not uniform, the layers will not be well bonded together, which will lead to the loss of part precision and even lead to the failure of the manufacturing process. [0003] The coating process currently has several methods such as natural type, sinking type, vacuum adsorption type, and waterfall type. At present, the mainstream is the vacuum adsorption type. Vacuum adsorption type coating device, the coating scraper ...
