Material cleaning separator for selective laser sintering

Abstract

The invention discloses a material cleaning separator for selective laser sintering. The material cleaning separator for selective laser sintering comprises a dust suction device, a dust collection device, a work room, a screening device and a collection box, wherein the dust suction device is arranged at the upper end of the dust collection device and is communicated with the dust collection device; the work room is arranged at the front end of the dust suction device; an upper protective window, a lower protective window and a workbench are also arranged on the work room; the workbench is arranged between the upper protective window and the lower protective window and protrudes from the work room; both the screening device and the dust collection box are arranged at the lower end of the work room. The material cleaning separator for the selective laser sintering provided by the invention is convenient to observe during working; a hand can extend into the work room for performing cleaning operation; meanwhile, material dust generated in a cleaning process is also reduced; remaining materials can be collected and screened quickly; the material staining caused by circulation is reduced; the requirements on personnel are reduced; the influence on environment is also reduced.

Description

technical field [0001] The invention belongs to auxiliary facilities used in SLS (selective laser sintering) technology in 3D printing, and in particular relates to a material cleaning and separating machine for selective laser sintering. Background technique [0002] 3D printing is a common name for additive manufacturing, and its core is the combination of digital, intelligent manufacturing and material science. Contrary to the traditional subtractive manufacturing method of cutting raw materials, the process of 3D printing is like building a wall with bricks, adding materials layer by layer, and finally forming a product. [0003] 3D printing does not require molds, and can directly manufacture sample prototypes, thus greatly reducing the time from drawings to objects. Parts of any complex shape can be decomposed into a series of two-dimensionally fabricated superpositions. This concept of rapid manufacturing has also derived a variety of different technology types. In ...

AI Technical Summary

Problems solved by technology

[0005] 1. Clean the workpiece in the open working room, because the particle size of the powder is between 20-40um, it still has a certain heat after 5 hours, and it is easy to cause dust under the action of hot air convection, which will cause serious damage to the working environment. Bad influence;

[0006] 2. After cleaning, the remaining materials need to be transferred to the screening system. After the screening is completed, they need to be taken out and packed. The material is transferred and transported multiple times, causing pollution to the material. During the transfer process, it is easy to miss the material and pollute the environment;

[0007] 3. Failure to form a complete set of solutions has a great impact on the environment and requires high personnel requirements
