Polishing machine for FDM (fused deposition modeling) formed parts and use method of polishing machine

Abstract

The invention discloses a polishing machine for FDM (fused deposition modeling) formed parts and a use method of the polishing machine. The polishing machine comprises a polishing machine body, a heating system, a condensation system, a constant-temperature circulation system and a control system, wherein the heating system, the condensation system, the constant-temperature circulation system and the control system are arranged in the polishing machine body. The polishing machine body comprises a sample drawer. The bottom of the sample drawer is of a latticed structure such as a silk screen. The heating system is arranged below the sample drawer and comprises a polishing solution box and a heating device used for heating the polishing solution box. An opening of the polishing solution box faces upwards and is right opposite to the bottom of the sample drawer. The condensation system corresponds to the sample drawer. The constant-temperature circulation system corresponds to the sample drawer. The heating system and the condensation system are both connected with the control system. A polishing solution is gasified after being heated by the heating system and rises into the sample drawer to conduct polishing on to-be-polished parts. The temperature in the sample drawer is lowered through refrigeration of the condensation system after polishing is finished so that the gasified polishing solution can be condensed and flow back to the polishing solution box.

Description

technical field [0001] The invention belongs to the field of equipment related to 3D printing technology, and in particular relates to a polishing machine for manufacturing FDM molded parts by fused deposition and a use method thereof. Background technique [0002] In the article "The Third Industrial Revolution", the British "Economist" regards 3D printing technology as one of the important symbols of the third industrial revolution. 3D printing technology can be widely used in various fields such as jewelry, footwear, industrial design, construction, automobile, aerospace, dentistry, medical treatment and even food. In the domestic and foreign sales markets, rapid prototyping equipment for Fused Deposition Modeling (FDM) accounts for the largest share. FDM technology, also known as fused filament molding, uses very fine filamentous plastic resin as the processing material, and extrudes the material through a small nozzle. The nozzle can move along the X-axis and Y-axis to...

AI Technical Summary

Problems solved by technology

[0003] However, for the FDM process, the molded parts are made of filamentous plastic resin layer by layer, which will inevitably cause step errors and the surface is very rough, which seriously affects the surface quality of the molded parts.

At present, the surface quality of FDM molded parts is mainly improved by manual grinding with sandpaper on the market, but the efficiency of manual grinding with sandpaper is slow and relies too much on the skills of workers, so the effect is not satisfactory
