Abstract

The invention relates to a method for generating a 3D printing support structure. The method comprises the following steps: reconstructing a support surface into a triangular mesh by using a Delaunay triangle subdivision method; performing classification extraction on the triangular grids by using a burning method to generate a unit set; and processing the unit set by using a cone intersection method to generate supporting points to reconstruct the supporting surface. Optimization of the supporting structure can be further realized. According to the generated supporting structure, the contact area between the supporting structure and the printing model is reduced, rapid separation of the supporting structure and the model is achieved, and the printing model is not prone to being damaged.

Description

technical field [0001] The invention relates to the field of 3D printing, in particular to a method for generating a 3D printing support structure. Background technique [0002] 3D printing is a rapid prototyping technology. The 3D printer is equipped with different printing materials such as metal, ceramics, plastics, sand, etc., and the printing materials are superimposed layer by layer through control to form a real object. The main process of the commonly used 3D printing technology is to melt the filamentous hot-melt material, and spray the melted material through a fine nozzle. After a layer of material is deposited, the workbench is lowered according to the set program or the nozzle is raised by one level of thickness, and then the above steps are repeated until the workpiece is manufactured. That is, by printing from the bottom layer. Therefore, for workpieces with suspended structures, they cannot be printed if there is no support structure underneath. [0003] A...
