3D printer based on mixed coordinate system

Abstract

The invention discloses a 3D printer based on a mixed coordinate system. The control box is fixed on the top surface of the aluminum frame by screws; the wire nozzle is fixed on the top of the aluminum frame by screws; the slide block of the guide rail is fixed on the aluminum frame by screws Inside, it is responsible for controlling the lifting of the lifting platform; the X-Z plane rotating turntable is fixed on the lifting platform by screws; the X-Y plane rotating turntable is fixed on the X-Z plane rotating turntable by screws; the heating bed is fixed on the X-Y plane by screws On the plane rotating turntable; the position of the printing forming point on the hot bed is achieved through the lifting of the lifting platform, the rotation of the X-Z plane rotating turntable, and the rotation of the X-Y plane rotating turntable, so that the printing forming point corresponds to the position of the filament nozzle. The printing molding point reaches any point in the space coordinate system to complete 3D printing; through this device, a 3D printer based on a mixed coordinate system can be completed.

Description

technical field [0001] The invention belongs to the field of 3D and relates to a 3D printing device based on a mixed coordinate system. Background technique [0002] At present, with the gradual development of 3D printing technology, various 3D printers have entered many fields such as military industry and medical treatment. As a relatively common 3D printer, FDM 3D printers mainly include gantry type, parallel arm type, etc. Because the accuracy of the screw rods on both sides cannot be completely consistent, long-term printing will cause the two sides to be uneven, which will affect the printing effect. Because the platform of the parallel arm type is fixed, it can only be adjusted by software or manually. X, Y, Z It is inconvenient to use the offset parameters of the direction to adjust the leveling, so by designing a 3D printer based on the mixed coordinate system, it can effectively solve the problems of printing needs to add support, poor printing effect, and inconven...

AI Technical Summary

Problems solved by technology

[0003] In order to solve the existing printing problems of FDM 3D printers such as the need to add support, poor printing effect, and inconvenient leveling, the present invention provides a 3D printer based on a mixed coordinate system. The 3D printer not only has good printing effect, but also does not require adjustment. Flat, with broad application prospects
