Problems solved by technology

[0004] However, for the support structure set up to support the inner cavity wall of the 3D printed object, or the support structure of other 3D printed objects with complex structures, the internal position of the 3D printed object is narrow, and the manual peeling method may not be able to clean or even peel off.
In addition, a small amount of interpenetration may occur between the supporting structure and the 3D printed object.

Abstract

The invention provides a 3D printed object aftertreatment device, system and method. A 3D printed object needing aftertreatment is placed in a sand blasting chamber, a gas compressor inputs compressedgas into a sand blasting gun; meanwhile, a sand pump inputs a water and sand mixture in a water and sand mixing tank into the sand blasting gun; the sand blasting gun pressurizes and sprays the waterand sand mixture through the compressed gas to the surface of the 3D printed objected from an outlet of the sand blasting gun, sand in the water and sand mixture polishes the surface of the 3D printed object under the pressure action, a support structure on the surface of the 3D printed object is completely removed, positions where the surface of the 3D printed object and the support structure interpenetrate as well as other positions can be polished, the efficiency and reliability in removing the support structure are improved, the 3D object with uniform surface roughness is obtained, besides, water in the water and sand mixture is cooled continuously during polishing, the condition that the thermal effect caused by friction affects the structure of the 3D printed object is prevented, and the aftertreatment reliability of the 3D printed object is improved.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a post-processing device, system and method for 3D printed objects. Background technique [0002] With the gradual development of industrial technology, the demand for complex parts and personalized customization has become stronger and stronger, and the application of additive manufacturing technology has emerged. Additive manufacturing technology has become the most popular technology in the 21st century due to its fast speed, high efficiency and intelligent operation. 3D printing technology is a branch of additive manufacturing. The objects printed by 3D printing technology can realize the rapid production of complex parts, shorten the research and development cycle, reduce the cost of research and development, and improve the efficiency of research and development. Some 3D printed objects have complex structures, and support structures need to be provided duri...
