Scraper for 3D printing and preparation method and application of scraper

Abstract

The invention relates to a scraper for 3D printing and a preparation method and application of the scraper. The scraper for 3D printing is characterized by being composed of a scraper body and a non-stick layer. According to the scraper, the quality of 3D printing can be improved, and material consumption is reduced.

Description

technical field [0001] The invention relates to a scraper for 3D printing, a preparation method and application thereof. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. [0003] 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and others. [0004] At present, the accuracy of 3D printing is gener...

AI Technical Summary

Problems solved by technology

[0004] At present, the accuracy of 3D printing is generally not high. In order to improve the accuracy of 3D printing, the slices are usually set very thin when building a 3D model. Although this method can improve the accuracy of 3D printing, 3D printing is printed layer by layer. As a benchmark, this increases the number of printing layers, resulting in low production efficiency and increased production costs

If the slice is set slightly thicker, the surface of the printed product will be relatively rough, which increases the trouble of subsequent processing, and even some products cannot be used even after subsequent processing, and become defective products. At present, there is no 3D printing that does not rely on adjustments. There is no way to increase the accuracy of printing by slicing, and there is no method that can improve the accuracy of 3D printing and improve production efficiency and save production costs

[0005] 3D printing slices are relatively thin, and 3D printing is based on slices for layer-by-layer printing, so the powder used for each printing is very small. In order to save costs and improve printing efficiency, the powder laid down each time It is precisely metered, and then the powder is scraped into the printing bin by a scraper. At present, there is no more accurate method of adding powder
