[0002] 3D printing (3DP) is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses 3D model files as the basis and uses powdered metal or plastic and other bondable materials to construct objects by printing layer by layer. It is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing, industrial design, etc., and then gradually used for the direct manufacturing of some products. There are already parts printed using this technology. This technology has been used in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automobiles, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms and other fields.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. Control the scraper to rotate as a whole inside the mounting plate.
