A high-precision 3D printer

Abstract

The invention relates to a high-precision 3D printer, which includes a frame, an optical machine, an optical-mechanical adjustment mechanism, a mounting plate, a material holding mechanism, an encoder, a Z-axis module, a printing platform, and a scraper height adjustment mechanism; wherein, the The optical machine is installed on the frame through the optical-mechanical adjustment mechanism, and the optical-mechanical adjustment mechanism can adjust the position of the optical machine; the mounting plate is fixed above the frame; the material holding mechanism is installed on the mounting plate; the encoder Cooperate with the material holding mechanism; the Z-axis module is connected to the frame, on which a printing platform is installed, and can drive the printing platform up and down; the scraper height adjustment mechanism is set on one side of the material holding mechanism, on which There is a scraper, and it can drive the scraper up and down to adjust the height of the scraper. The high-precision 3D printer of the present invention has many advantages such as adjustable optical-mechanical precision, high degree of automation and stable performance.

Description

【Technical field】 [0001] The invention relates to a printer, in particular to a high-precision 3D printer, and belongs to the technical field of 3D printing. 【Background technique】 [0002] A 3D printer, also known as a three-dimensional printer, is a machine that uses cumulative manufacturing technology (that is, rapid prototyping technology). Its principle is to put data and raw materials into a 3D printer, and the machine builds products layer by layer according to the program. [0003] The 3D printer of the prior art is shown in the invention patent application No. 201610863393.8 of the People's Republic of China. However, the above-mentioned printers often have the following defects in actual use: [0004] 1. The position of the optical machine of this printer is fixed after manual focusing, and the projection range of the optical machine cannot be adjusted according to needs, so its accuracy cannot be adjusted, which greatly reduces the printing accuracy of the printe...

AI Technical Summary

Problems solved by technology

[0004] 1. The position of the optical machine of this printer is fixed after manual focusing, and the projection range of the optical machine cannot be adjusted according to the needs, so its accuracy cannot be adjusted, which greatly reduces the printing accuracy of the printer

[0005] 2. The resin cartridge of this printer is driven by gears, but its rotation angle cannot be accurately measured and controlled, which has certain limitations

[0006] 3. The height of the scraper of this printer can only be adjusted manually, which is cumbersome to adjust and the adjustment accuracy is low
