Micro-pore atomizer polishing machine and polishing method

Abstract

The invention relates to a micro-pore atomizer polishing machine. A fan is arranged on the top surface of a base body, atomized alcohol produced by an atomizer is blown up through the fan, and the atomized alcohol is driven to make movement from the bottom to the top, so that the atomized alcohol can fall on the downward surface of a 3D print object with a complicated structure, all surfaces of the 3D print object can be polished, and the surface effect of the 3D print object is improved.

Description

technical field [0001] The invention relates to a microporous atomizer polishing machine and a polishing method, belonging to the technical field of 3D printing equipment. Background technique [0002] 3D printing technology appeared in the 1980s, also known as "rapid prototyping technology". Its biggest advantage is that any object can be directly generated from the graphic data designed by the computer without machining or molds, thereby greatly shortening the product development cycle, improving productivity and reducing production costs. Therefore, it is widely used in art and industry. 3D printing technology can be divided into stereolithography (stcmolithography, SLA), laminated object manufacturing (Laminated Object Manufacturing, LOM), selective laser sintering (Selective Laser Sintering, SLS) and fused deposition manufacturing ( Fused Deposition Modeling, FDM) and so on. The most essential difference between the FDM rapid prototyping system and other systems is t...

Problems solved by technology

[0003] In order to improve the surface smoothness and finish of 3D printed polymer products, polishing equipment and polishing machines are usually used for subsequent surface fine processing of 3D printed products. The existing surface polishing methods mainly include: (1) sandpaper grinding, manual grinding or using Abrasive belt sander is used for grinding and polishing, but this kind of polishing method is difficult to process tiny products, the grinding efficiency is low, time-consuming, and will cause damage to the product to varying degrees, reducing printing accuracy; (2) Pearlescent treatment, use the nozzle to polish The product is polished by jetting abrasives at high speed. This method damages the surface of the product and cannot be very smooth. Alcohol, etc.) in the atomization tank, the surface of the product is melted by solvent droplets to achieve a smooth effect. Compared with the previous two methods, the atomization and melting method is simple and easy to operate, low in cost, good in polishing effect, and easy to popularize and use

[0004] In the prior art, the microporous atomizer polishing machine sprays alcohol into the air and adheres to the surface of the 3D printed object through the droplets, thereby polishing the surface of the 3D printed object. However, as the 3D printed model becomes more and more The more complicated it is, the traditional microporous atomizer polishing machine is difficult to accurately spray the alcohol droplets to each surface of the 3D printed object, which makes it difficult for some surfaces to be polished.
