Problems solved by technology

Chinese patent CN209140590U and Chinese patent CN208051704U use chemical methods to polish, and it is difficult to control the relationship between the length of time the 3D model is immersed in the polishing solution and the amount of polishing
Chinese patent CN208035398U uses heating in the heating and polishing chamber to melt the surface of the 3D model to be processed to eliminate the layer pattern of the model to obtain a smoother surface, but this method is likely to cause thermal deformation of the 3D printing model

Abstract

A 3D printing model laser polishing system and its use method, the system includes a main frame and a laser translation device installed on the main frame, a Z-direction displacement component, a surface cleaning device, a gas purification device, a control device and a power supply device, and a Z-direction displacement component There is a model rotation device installed on it; the method of use uses ultraviolet laser beams to uniformly polish and partially polish the surface of the 3D printing model, and purify the dust and harmful gases generated during the polishing process in real time, effectively reducing the thermal deformation and mechanical damage of the 3D printing model. Deformation, fine processing can be achieved.

Description

technical field [0001] The invention belongs to the technical field of 3D printing, and in particular relates to a laser polishing system for a 3D printing model and an application method thereof. Background technique [0002] 3D printing is a rapid prototyping technology that builds 3D models based on two-dimensional modeling methods. Due to the influence of layered printing and superimposed molding processes, stepped layers are inevitably formed on the surface of 3D printed models. Printing layer texture makes the appearance of 3D model rough, which has a great influence on the surface accuracy of the model. Using the traditional sandpaper grinding method and soil filling method to process the 3D printing model, the grinding accuracy is difficult to guarantee, and the workload is relatively large. Chinese patent CN209140590U fixes the 3D printing model on a grid plate, then immerses it in a polishing liquid tank for polishing, and uses a drying fan to blast and dry it. C...
