Abstract

The invention relates to a 3D printing model surface treatment method. The 3D printing model surface treatment method is used for treating a 3D printing model with one or more concave parts on the surface, and the 3D printing model surface treatment method comprises the following steps: coating a liquid photocuring material on the to-be-treated surface of the 3D printing model; covering the to-be-treated surface of the 3D printing model with a flexible thin film, and applying acting force to the flexible thin film so that the flexible thin film can deform and form a preset constraint face opposite to the to-be-treated surface of the 3D printing model, wherein the concave parts are filled with the liquid photocuring material through the preset constraint face; and irradiating the concave parts with ultraviolet light with specific wavelength to cure the liquid photocuring material in the concave parts. According to the provided 3D printing model surface treatment method, the problem that an existing method for treating the surface of a 3D printing model is not high in treatment precision is effectively solved.

Description

technical field [0001] The invention relates to the technical field of additive manufacturing, in particular to a surface treatment method for a 3D printing model. Background technique [0002] 3D printing is a kind of rapid prototyping technology, also known as additive manufacturing. 3D printing is a technology that constructs objects by printing layer by layer based on digital model files. With the continuous maturity of 3D printing technology and the continuous improvement of the stability of equipment used in 3D printing technology, the application range of 3D printing technology continues to expand. [0003] Among them, the light-curing 3D printing method uses ultraviolet light or other light sources in a specific wavelength range to irradiate the printing material and triggers a photochemical reaction, so that the printing material in the area irradiated by the light source is solidified from a liquid to a solid printing layer, and the printing layer is stacked. 3D ...
