Molding mechanism of metal 3D printing device

Abstract

The invention discloses a molding mechanism of a metal 3D printing device. The molding mechanism of the metal 3D printing device comprises a molding platform arranged on a base of the metal 3D printing device, a movable storage tank for storing metal raw materials, a lifting module for driving the molding platform and a baseplate of the movable storage tank to move, and a scraper module for processing the metal raw materials. The molding mechanism of the metal 3D printing device only consists of the molding platform, the movable storage tank, the lifting module and the scraper module, so thatthe whole structure is simple and small; and the lifting module controls the molding platform and the baseplate of the movable storage tank to move up and down through two lifting motors, so that stability and speediness are achieved, and high-efficiency molding can be realized.

Description

technical field [0001] The invention relates to a forming mechanism of a metal 3D printing device, which belongs to the field of 3D printing. Background technique [0002] At present, conventional metal 3D printing devices on the market generally adopt SLM technology. SLM: Selective lasermelting (selective laser melting), is a rapid prototyping technology of metal powder, which can directly form metal parts. However, the use of SLM technology will have the following defects: [0003] 1. The molding mechanism of the SLM equipment has low molding efficiency during printing, and the precision of the molding parts is low, and the surface is relatively rough; [0004] 2. The forming mechanism of SLM equipment is relatively complicated, and there will be problems of large volume, difficult control and high cost. [0005] In view of this, the inventor conducted research on this, and specially developed a metal 3D printing device forming mechanism, and this case arose from it. C...
