[0002] 3D printing (3DP) is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that uses digital model files as the basis, and uses bondable materials such as powdered metal or plastic to construct objects by printing layer by layer. 3D printing is usually achieved using a digital technology material printer. 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 applications 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.

[0003] During the installation of the scraper strip of the 3D printer powder spreader, it is usually installed by pressing it flat by hand. Since the scraper strip itself is relatively soft, the height of the scraper strip will be inconsistent during the installation process, resulting in the need for repeated installation. This installation method is not only inefficient and time-consuming, but also often fails to meet the requirements of powder spreading, causing adverse effects on users. Summary of the invention
