a 3d printer

Abstract

The invention discloses a 3D printer. The structure includes a fixing screw, a printer main body, a window, and a supporting foot. The fixing screw is threadedly connected to the upper end of the printer main body. The window is embedded in the right side of the printer main body. The four corners of the lower surface of the main body of the printer, the main body of the printer includes the main body shell, the horizontal drive mechanism, the print head mechanism, the vertical drive mechanism, the placement mechanism, the sandblasting and polishing mechanism, and the vertical movement mechanism. The vibration generated by the movement of the placement mechanism makes the cooling mechanism work. The entity is cooled to ensure that the entity is shaped without being damaged by high temperature. The medium beads are sprayed at high speed by the sandblasting polishing mechanism to achieve the polishing effect, which saves the work of the operator and makes the outer surface of the entity more beautiful and smooth. The vertical movement mechanism makes The sandblasting and polishing mechanism moves up and down, and the sandblasting and polishing of the entity is more comprehensive.

Description

technical field [0001] The invention relates to the field of 3D printers, in particular to a 3D printer. Background technique [0002] The 3D printing process is the world's advanced technology in recent decades. It is different from the "removal method" of traditional cutting and other materials. The additive technology will use fine raw materials to be stacked layer by layer to generate a three-dimensional entity, so it is popularly called It is called "3D printing", but the 3D printer in the prior art melts the raw materials at high temperature and then shapes them during the printing process. If there is no rapid cooling after molding, the entity will be deformed, and the outer surface of the printed entity will be relatively rough. There is manual polishing and polishing, which is time-consuming and laborious. Contents of the invention [0003] Aiming at the deficiencies of the prior art, the present invention is realized through the following technical scheme: 3D pr...
