Three-dimensional printer with polishing function

Abstract

The invention provides a three-dimensional printer with a polishing function. The three-dimensional printer comprises a base, a supporting frame, a rotary table, a lifting device, a worktable, a printing device and a polishing device, wherein the supporting frame is arranged on the base, the rotary table is mounted on the base in a rotating manner, the lifting device is arranged on the rotary table, and the worktable is horizontally arranged on the lifting device; the printing device comprises a printing nozzle, a feed pipe, a material storing box, a positive pressure device and a negative pressure device, wherein materials in the material storing box can be fed to the printing nozzle through the feed pipe by the positive pressure device, and negative pressure can be provided for the material storing box by the negative pressure device, so that the materials in the printing nozzle and the feed pipe flow into the material storing box back; the polishing device comprises a fixing base, a connecting rod, a polishing head and a first driving mechanism, wherein the fixing base is mounted at the top end of the supporting frame in a sliding manner, the first driving mechanism is connected with the fixing base, the connecting rod is positioned under the fixing base, the first end of the connecting rod is connected with the fixing base, and the second end of the connecting rod is connected with the polishing head.

Description

technical field [0001] The invention relates to the technical field of three-dimensional rapid prototyping, in particular to a three-dimensional printer with a grinding function. Background technique [0002] 3D printing is a rapid prototyping technology, that is, based on digital model files, using powdered metal or plastic and other bondable materials to construct objects by layer-by-layer printing. [0003] Generally, for 3D printers with large material consumption, the storage box is set separately, and the storage box is connected to the printing nozzle through the feeding tube. After printing, if the materials in the printing nozzle and the feeding tube are not discharged in time, it is easy to cause printing. The nozzle and feeding pipe are blocked, which will affect the next use; because the 3D printer uses layer-by-layer printing to print, when printing some curved surfaces, the outer surface is prone to jaggedness, which affects product quality.
