Abstract

The invention provides a selective-laser-sintering 3D printing demonstrator, and relates to the field of 3D printing equipment. The selective-laser-sintering 3D printing demonstrator comprises a shell (7), a laser control system (1), a display screen (2), a forming chamber (3), a protective gas bottle (6) and a material recycling chamber (8). The laser control system (1) is mounted on the upper portion of the shell (7), and is used for generating laser. The display screen (2) is mounted on the shell (7), and is connected with the laser control system (1). The forming chamber (3) is mounted in the middle of the shell (7), and is located below the laser control system (1). The protective gas bottle (6) is mounted on the side wall of the shell (7), and is used for injecting protective gases into the forming chamber (3). The material recycling chamber (8) is mounted on the lower portion of the shell (7). The selective-laser-sintering 3D printing demonstrator has the advantages of simple structure, portability in size, low process cost and machine cost, greatly-reduced 3D printing threshold, and convenience in demonstration and teaching.

Description

technical field

[0001] The invention relates to the field of 3D printing equipment, in particular to a selective laser sintering 3D printing demonstration machine. Background technique

[0002] 3D printing is a rapid prototyping technology that uses bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing based on digital model files. The rapid development of 3D printing technology has attracted extensive attention from the state and society, and it is playing an increasingly important role in the development of science and technology and industrial progress. At present, 3D printers based on the principle of FDM fusion deposition have been widely used in education and personal fields due to their low cost, simple structure, and small size.

[0003] Based on SLS (Selective laser sintering) selective laser sintering and 3D printing technology based on SLM (Selective laser melting) selective laser melting principle, there are many ty...
