A 3D printed article surface polishing and strengthening device

Abstract

The invention discloses a 3D printing object surface polishing and strengthening device. The device comprises an outer shell, a top cover arranged at the top of the outer shell, a bottom cover arranged at the bottom of the outer shell, a separation plate arranged in the outer shell, a polishing liquid holding tank formed above the separation plate, a liner arranged above the polishing liquid holding tank, a tray arranged in the liner, an electric heating plate arranged under the separation plate, and an electronic relay arranged on the bottom cover. The 3D printing object surface polishing andstrengthening device can hold polished objects made of multiple materials and multiple types of polishing liquid, is uniform in polishing, high in polishing efficiency and excellent in polishing effect, improves the rupture strength and the toughness of the polished objects, recycles the polishing liquid, is safe in operation, protects the environment, and saves the cost; and the polishing devicecan be zoomed according to equal proportion, and the capacity can be increased or reduced according to special polishing demands, so that the size application range of the polished objects is more free.

Description

technical field [0001] The invention relates to the technical field of 3D printing, in particular to a surface polishing and strengthening device for 3D printing objects. Background technique [0002] 3D printing technology 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. The technology has applications in jewelry, footwear, industrial design, architecture, engineering and construction, automotive, aerospace, dental and medical industries, education, geographic information systems, civil engineering, firearms, and other fields. However, since the items printed by the 3D printer are superimposed by layers with a thickness of about 100 microns, in the process of layer-to-layer accumulation, there are often internal defects and uneven stress, and the surface of the printed items is very rough. , seriously restricting the appl...

AI Technical Summary

Problems solved by technology

[0005] At present, the 3D printing polishing machines using high-temperature atomization covering polishing technology on the market have the following problems: there is a single specification for the material composition of the polished object; the chemical solution used is toxic and cannot be used directly without professional operating equipment; chemical solution recycling If it is not in place, it will cause environmental pollution; the price is too expensive for ordinary people to afford, and the volume of the slightly cheaper ones that can be polished is very small, so they can only polish some miniature models; there are also uneven polishing and excessive local polishing.
