Abstract

The invention discloses a spherical coordinate system 3D printer. A hot bed is fixed to the bottom of an outer frame. A filament guiding motor and a filament discharging sprayer are fixed to a telescopic rod in the R direction to control resin filaments to be discharged, and the telescopic rod in the R direction can control the sprayer to move in the R direction. The telescopic rod in the R direction is fixed to a Y-Z plane swing arm, and the Y-Z plane swing arm can control the sprayer to rotate on a Y-Z plane. The Y-Z plane swing arm is fixed to an X-Y plane rotary table. The X-Y plane rotary table can control the sprayer to rotate on an X-Y plane, and is hung at the top of the outer frame. The X-Y plane rotary table controls the sprayer to rotate on the Y-Z plane, the Y-Z plane swing arm controls the sprayer to rotate on the Y-Z plane, the telescopic rod in the R direction controls the sprayer to move in the R direction, and thus spherical coordinates (R, Theta and Phi) of the sprayer in a spherical coordinate system can be controlled. By the adoption of the device, the spherical coordinate system 3D printer can be obtained.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and relates to a spherical coordinate system 3D printing device. 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 adjust the level by using the offset parameters of the direction, so by designing a spherical coordinate system 3D printer, it can effectively solve the problems of poor printing effect and inconvenient leveling, which has cert...
