Abstract

The invention provides a three-dimensional printing method for a hollow three-dimensional model, which decomposes the model into a skin layer and a rigid frame layer, and prints after hollowing out the rigid frame layer. The specific steps are as follows: obtaining a three-dimensional model of an object; obtaining a skin layer according to the three-dimensional model Model and parameters; extract the feature points of the three-dimensional model, construct the rigid frame model, and the rigid frame model is a hollow structure; wrap the skin layer model on the outer periphery of the rigid frame model, and adjust the rigid frame model to obtain the target model; Calculate target model parameters; slice and layer the target model; print the target model. The three-dimensional printing method for a hollow three-dimensional model proposed by the present invention not only saves materials, but also reduces costs, reduces printing time and improves efficiency.

Description

technical field [0001] The invention relates to the technical field, in particular to a three-dimensional printing method for a hollow three-dimensional model Background technique [0002] Three-dimensional printing, also known as 3D printing (Three Dimensions Printing), belongs to a kind of rapid prototyping technology. It is a technology based on digital model files, using bondable materials such as powdered metal or plastic, to construct objects by layer-by-layer printing. In the past, it was often used to make models in the fields of mold manufacturing and industrial design, and is now gradually being used in the direct manufacture of some products, especially some high-value products (such as hip joints or teeth, or aircraft parts) have used this Parts printed by this technology. 3D printing is usually realized by using a digital technology material printer. Since the 3D printing technology is relatively complicated, the cost of 3D printing is also relatively high. ...
