Abstract

A desktop-level 3D printing device relates to a 3D printing device. The present invention solves the problems of relatively single material of existing miniaturized 3D printing equipment, resulting in a narrow use range of parts, and the problems of low automation, low printing precision and poor printing effect of 3D printing equipment. The shell (2) is set on the frame (1); the 3D printing device also includes an optical path mechanism (3), a sealing heating mechanism (4), a powder supply mechanism (5) and a powder spreading mechanism (6). Mechanism (3), sealing heating mechanism (4), and powder feeding mechanism (5) are installed in the frame (1) sequentially from top to bottom, and powder spreading mechanism (6) is installed in the sealing heating mechanism (4). The invention is used for desktop-level 3D printing.

Description

technical field [0001] The invention relates to a printing device, in particular to a desktop-level 3D printing device, which belongs to the field of 3D printing. Background technique [0002] 3D printing is a type of rapid prototyping technology, also known as additive manufacturing. It is a technology that constructs objects by layer-by-layer printing based on digital model files and using bondable materials such as powder metal or plastic. 3D printing is usually realized by using digital control technology combined with corresponding materials using printing equipment. It is often used to make models in the fields of mold manufacturing, industrial design, etc., and is gradually used for the direct manufacturing 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, geogr...
