3D printer

Abstract

The invention discloses a 3D printer. The 3D printer structurally comprises a fixing screw, a printer main body, a window and four supporting legs; the fixing screw is in threaded connection with theupper end of the printer main body; the window is embedded in the right side surface of the printer main body; the upper ends of the supporting legs are welded to the four corners of the lower surfaceof the printer main body; and the printer main body comprises a main body outer shell, a horizontal driving mechanism, a printing nozzle mechanism, a vertical driving mechanism, a placement mechanism, a sandblasting polishing mechanism and a vertical moving mechanism. A cooling mechanism is made operate to cool a printed solid body through vibration generated by movement of the placement mechanism, solid body molding is ensured, the shape is not damaged by high temperature, the polishing effect is achieved through high-speed jetting of medium beads through the sandblasting polishing mechanism, operation of operators is omitted, in addition, the outer surface of the solid body is more beautiful and smooth, and sandblasting polishing of the solid body is more thorough due to up-down movement of the sandblasting polishing mechanism through the vertical moving mechanism.

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...
