Rubber powder laser sintering 3D printing forming device and printing method

Abstract

The invention discloses a rubber powder laser sintering 3D printing forming device and a printing method. A machine body is included, the bottom of the machine body is connected with a printing platform through a lifting structure, a sintering device is arranged at the top end of the machine body, supporting sliding rods fixed to the two sides of the machine body are arranged under the sintering device, the supporting sliding rods are provided with a powder spreading device, and the sintering device comprises a moving guide rail arranged at the top end of the machine body; and a first electricsliding block is mounted on the moving guide rail, the bottom end of the first electric sliding rod is connected with a scanning mirror through a rotating connecting member, a laser generator is arranged on the side of the scanning mirror, and a refractor assembly is arranged between the laser generator and the scanning mirror. The device is high in sintering precision and sufficient in sintering, does not affect surrounding materials, enables rubber powder to be more evenly spread, is higher in spreading precision, and avoids the position deviation of the rubber powder; and in addition, therubber powder prepared by the device has better quality, all components are more uniformly mixed, and the quality of products can be ensured.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a rubber powder laser sintering 3D printing molding device and a printing method. Background technique [0002] 3D printing (3DP) is a kind of rapid prototyping technology. It is a technology based on digital model files and using bondable materials such as powdered metal or plastic to construct objects by layer-by-layer printing. 3D printing is usually achieved using digital technology material printers. It is often used to make models in the fields of mold manufacturing and industrial design, and is gradually used in the direct manufacture of some products. There are already parts printed using this technology. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction (AEC), automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and others. 3D printing te...

AI Technical Summary

Problems solved by technology

[0006] (1) Existing 3D printing molding devices usually use microwave sintering when sintering rubber powder, but microwave sintering has low sintering precision, insufficient sintering, and the microwave coverage area is large, which is easy to affect the surrounding raw materials. 3D printing quality;

[0007] (2) Existing 3D printing molding devices usually use powder spreading rollers when spreading powder, but the powder spreading rollers are not uniform in powder spreading, and the powder spreading accuracy is not high, it is easy to make the position of rubber powder deviate from the expected position, thus affecting 3D printing effect;

[0008] (3) The rubber powder used in the existing 3D printing molding device is usually made of rubber pulverization, the quality is not good, and the ingredients are mixed unevenly, which affects the quality of the product
