Problems solved by technology

[0003] 3D printers are becoming more and more popular, but because FDM technology is restricted by the molding process and molding speed, it is difficult for the model printed by the FDM technology printer to overcome the layered texture formed in the Z-axis direction, and the surface finish and coloring of the model cannot meet the requirements. Actual use requirements

Abstract

The invention provides a surface treatment process used for treating the surface of a model based on the FDM printing technology, and relates to the technical field of surface treatment. The surface treatment process comprises the steps of sand blasting, first-time grinding, first-time spraying, second-time grinding, second-time spraying, third-time grinding and a paint spraying process. In the grinding process, different types of abrasive paper are adopted, and the thickness of each time of spraying ranges from 0.2 mm to 0.3 mm. In the step of paint spraying, after polyester main colored paint, a curing agent and a diluent are mainly mixed according to the weight ratio being 1:1:0.2, the model surface is sprayed, and a finishing coat layer with the thickness ranging from 40 micrometers to60 micrometers is formed. Through the above surface treatment process, the conditions of model layering textures, smoothness and coloring can be greatly improved, surface levelness and smoothness ofa bottom material in front of finishing coat can be met, and the actual use requirement can be met.

Description

technical field [0001] The invention relates to the technical field of surface treatment, in particular to a surface treatment process. Background technique [0002] Fused deposition rapid prototyping technology, referred to as FDM (Fused Deposition Modeling), under the control of the computer, the heating nozzle moves in the X-Y plane according to the interface contour information of the product parts, and the thermoplastic filamentary material is sent to the hot melt nozzle by the wire feeding mechanism. It is heated and melted into a semi-liquid state in the nozzle, and then extruded, selectively coated on the workbench, and forms a layer of thin sheets after rapid cooling. After the cross-section of one layer is formed, the workbench is lowered to a certain height, and then the next layer of cladding is performed, and this cycle is repeated to finally form a three-dimensional product part. [0003] 3D printers are becoming more and more popular, but because FDM technolo...
