SLA additive manufacturing device convenient to recycle

Abstract

An SLA additive manufacturing device convenient to recycle comprises a machine body and a plurality of bottom feet fixedly arranged on the lower wall of the machine body, an inner cavity is formed in the machine body, a liquid groove is formed in the inner cavity, a top plate is fixedly arranged on the lower wall of the liquid groove, the top plate is arranged in an L shape, and a movable rod is fixedly arranged on the upper wall of the end, away from the liquid groove, of the top plate; a movable plate is fixedly arranged at the upper end of the movable rod, a cavity is fixedly formed in the side wall of the inner cavity, the movable plate is arranged in the cavity in a sliding mode, an inductance material is arranged between the upper end of the movable plate and the cavity, an electromagnet is fixedly arranged on the side wall of the cavity, and the electromagnet is arranged in the machine body. And the lower end of the electromagnet is electrically connected with a conductive rod. The printing device is ingenious in design and scientific and reasonable in structure, the workbench is well limited during printing, meanwhile, the synchronism of limiting and printing is achieved, the recovery process of a model after printing is also facilitated, and the situation of damage is prevented.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to an SLA additive manufacturing device that is convenient for recycling. Background technique [0002] Additive manufacturing, commonly known as 3D printing, integrates computer-aided design, material processing and molding technology, and is based on digital model files to manufacture physical objects. SLA is one of several technologies for light-curing 3D printing; [0003] The principle of this technology is: the liquid tank is filled with liquid photosensitive resin, which will be cured quickly under the irradiation of the ultraviolet laser beam emitted by the laser. The height of the laser beam focused by the lens scans the profile of the section along the liquid surface according to the machine instruction, and the resin in the scanning area solidifies quickly, thus completing the processing of a layer of section and obtaining a layer of plastic sheet, and then...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to solve the shortcomings existing in the prior art, such as: in the existing printing process, due to the slight toxicity of the photosensitive resin, there is pollution to the environment, and there is an allergic reaction to some human skin, but there is often no Protecting it is not conducive to the environment and human safety; and the strength, stiffness, and heat resistance of the resin material are limited after molding, and it is brittle and easy to break after curing, and it is easy to damage the molded parts during recycling.
