Embodiment Construction

[0027] In order to make the purpose, content and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0028] This embodiment proposes a visual 3D printing equipment circulation filtration system simulation device, its structure is as follows figure 1 shown. The simulation device includes a forming simulation cabin 1 , an air inlet 2 , a smoke generator 3 , a circulation fan 4 , a smoke filter 5 , an air outlet 6 and a circulation pipe 7 . Wherein, starting from the circulation fan 4, the connection sequence is circulation fan 4-air inlet 2-forming simulation cabin 1-air outlet 6-smoke filter 5-circulation fan 4. The smoke generator 3 is connected between the circulating fan 4 and the air inlet 2 by using a T-shaped pipe. The forming simulation cabin 1 is made of transparent material such as glass or plexiglass, and it...

Abstract

The invention belongs to the technical field of 3D printing equipment, and relates to a visualized 3D printing equipment circulation filtering system simulation device and a method. According to the device and method of the invention, a simulation test design idea is adopted; an additive manufacturing equipment circulation system is simplified; a transparent glass material is adopted to simulate aforming cabin, so that the visualization of a circulation system wind field can be realized; an air inlet structure is of a segmented structure, and is connected by snap rings, and therefore, disassembly and installation can be facilitated; the air inlet structure is formed by means of a non-metal 3D printing technology, and therefore, the rapid design, manufacturing and verification of the air inlet structure can be realized; and the research and development cycle of the air inlet structure is shortened, the research and development costs of the air inlet structure are reduced, and the problem of the iteration cycle of the structural design and manufacture of a current circulation system can be solved. The device and method of the invention are suitable for the design of a circulation system in the research and development process of industrial additive manufacturing equipment, especially powder bed laser selective laser melting (SLM) and has a high value in the research and development of the equipment.

Description

technical field [0001] The invention belongs to the technical field of 3D printing equipment, and in particular relates to a simulation device and method for a circulation filtration system of visualized 3D printing equipment. Background technique [0002] 3D printing technology is a technology based on the principle of discrete accumulation, integrated computer graphics processing, digital information and control, electromechanical control technology and material technology, and adopts the method of accumulating materials layer by layer to realize the technology of rapid free forming of parts. [0003] The development of 3D printing technology largely depends on the development of equipment. The quality of product printing depends on the stability of printing equipment. The stability of equipment will directly affect whether the product can be successfully printed. There are powder splashes and smoke during the powder bed selective melting forming process. Therefore, in thi...
