3D printing machine

Abstract

The invention discloses a 3D printing machine. The 3D printing machine comprises a machine box, a forming platform assembly mounted at the upper part of the machine box, a material disc, an adjustable optimal machine assembly mounted at the lower part of the machine box, and a control platform mounted outside the machine box, wherein the forming platform assembly and the adjustable optimal machine assembly are provided with motors; a force feedback system is arranged on the forming platform assembly; and the motors and the force feedback system are electrically connected with a control system of the control platform, so that the lifting speed of a forming platform can be effectively controlled through the mutual cooperation of the control system and the force feedback system. According to the 3D printing machine, an optical machine at the lower part of the machine box is designed as the adjustable optimal machine assembly, the up-and-down motion of the optical machine is controlled through an adjusting device, the focal length is adjustable, and the 3D printing machine is applicable to printing of various breadths and is applicable to printing of printing products of various precision as well.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a 3D printer. Background technique [0002] Existing 3D printers are composed of an optical machine, a material tray, a forming platform, and a motor that drives the forming platform from bottom to top. The forming platform does not have a sensor system, so it is impossible to accurately control the printing process, and often When the forming platform and the material tray are peeled off, the printing fault is caused by too fast separation; in addition, the optical machine of the existing 3D printer is manually adjusted and locked on the chassis after the focus is fixed, while the locked fixed focus light The precision of the 3D printer cannot be adjusted, so if you want to print a variety of products with different precision requirements, because the optical-mechanical focus corresponding to the products with different precision requirements is different, it limits the scop...

Problems solved by technology

[0002] Existing 3D printers are composed of an optical machine, a material tray, a forming platform, and a motor that drives the forming platform from bottom to top. The forming platform does not have a sensor system, so it is impossible to precisely control the printing process, and often When the forming platform and the material tray are peeled off, the printing fault is caused by too fast separation; in addition, the optical machine of the existing 3D printer is manually adjusted and locked on the chassis after the focus is fixed, while the locked fixed-focus light The precision of the 3D printer cannot be adjusted, so if you want to print a variety of products with different precision requirements, because the optical-mechanical focus corresponding to the products with different precision requirements is different, it limits the scope of use of the 3D printer, and the existing The light source of the optical machine is all visible light. This kind of visible light machine generates a lot of heat during the printing process, and the light intensity is not easy to control.

The overall service life of existing 3D printers is short, and parts often need to be replaced, which leads to high consumption costs
