Abstract

The invention provides an optimizing and fast modeling method for a three-dimensional printing hole. The method comprises the steps of performing structural topological optimization for a finite element model to obtain a gray value of the finite element model; determining the porosity of each corresponding unit according to the gray value of each unit; determining the shape and position of the hole according to the porosity of each unit and the finite element shape functions; generating the hole. With the adoption of the method, the three-dimensional structural strength can be optimized; the three-dimensional printing material consumption can be saved; the size and distribution of the hole in a three-dimensional model structure can be effectively displayed; in addition, the hole can be quickly formed in a three-dimensional model.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, and more specifically, to a method for optimizing and rapid modeling of three-dimensional printing pores. Background technique [0002] 3D printing is the product of the further development of rapid prototyping technology, and 3D printing technology has now entered designers' offices and even ordinary homes. [0003] One of the big advantages of 3D printing is that it is possible to print complex structures, such as pores in structures. At present, due to the limitations of modeling tools, 3D printing structures usually have no pores or uniform pores, that is to say, all the pores are of the same size. However, non-uniform pores are often required for practical applications in medical devices, human implants, plastic and metal processing, and building material structures; non-uniform pores can help build stronger 3D-printed structures using less material. [0004] However, there is...
