Spherical coordinate frame 3D printer with rotary hot bed

Abstract

The invention discloses a spherical coordinate frame 3D printer with a rotary hot bed. The X-Y plane rotary hot bed is fixed at the bottom of an outer frame and can control rotation of print points of a silk yielding nozzle on an X-Y plane; a silk guiding motor and the silk yielding nozzle are fixed on an R-direction telescopic rod to control resin silk to yield the silk, and the R-direction telescopic rod can control moving of the nozzle in an R direction; the R-direction telescopic rod is fixed on a Y-Z plane swing arm, and the Y-Z plane swing arm can control rotation of the nozzle on a Y-Z plane; the Y-Z plane swing arm is fixed at the top of the outer frame. The Y-Z plane swing arm can control moving of the nozzle in the R direction, the X-Y plane rotary hot bed can control the rotation of the print points of the silk yielding nozzle on the X-Y plane, the Y-Z plane swing arm can control the rotation of the nozzle on the Y-Z plane, and accordingly spherical coordinates (R, theta, phi) in which the nozzle is located in a spherical coordinate frame can be controlled; through these devices, the spherical coordinate frame 3D printer with the rotary hot bed can be achieved.

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...
