Powder feeding anti-blocking metal 3D printer

Abstract

The metal 3D printer comprises a 3D printer body, a transition disc seat is fixedly connected to one side of the top end of the 3D printer body, a disc seat cover plate is arranged at the top of the transition disc seat, a powder storage tank is arranged at the bottom of the front face of the disc seat cover plate, and a driving motor is arranged at the top of the center of the disc seat cover plate. The bottom of the driving motor is connected with a speed reducer, the bottom of the speed reducer is connected with an axis column rod, the outer wall of the bottom end of the axis column rod is fixedly connected with an annular filter screen, the outer wall of the annular filter screen is fixedly connected with an annular check ring, and the annular check ring is movably connected into a transition disc base. According to the 3D printer, the rotating speed output by the driving motor is reduced through the speed reducer, the hexagonal prism and the connecting insertion sleeve are used for driving the annular filter screen fixed to the outer wall of the bottom end of the axis column rod to continuously rotate, and it can be guaranteed that 3D printing work is smoothly carried out when local meshes of the annular filter screen are blocked.

Description

technical field [0001] The invention relates to the technical field of metal 3D printers, and more particularly, the invention relates to a metal 3D printer with powder feeding and anti-clogging. Background technique [0002] 3D printing uses continuous physical layers to create target three-dimensional objects in additive manufacturing technology. 3D printers are functionally the same as laser forming technology, using layered processing and superposition forming, that is, by adding materials layer by layer to generate 3D objects, which is different from traditional methods. The material removal processing technology is completely different. With the continuous advancement of 3D printing technology, it has been able to produce a 3D model that is very close to the appearance, feel and function of the prototype. When using metal powder for 3D printing work, metal powder is used as the printing raw material. , according to the design model, the high temperature of the laser be...
