Problems solved by technology

However, this is relatively easy to cause the liquid molding material to remain in the hollow part because the hollow part will be closed by the shell during the molding process, and the remaining liquid molding material will easily affect the structure and stability of the three-dimensional structure.

Abstract

A method for three-dimensional printing for forming a three-dimensional structure on a moving platform is provided. The three-dimensional structure includes a shell portion and a foamy filling portion. The method includes the following: a digital shell model of the three-dimensional structure is built. Next, the digital shell model is sliced into a plurality of cross-section information. Next, a corresponding liquid forming material is cured on the moving platform according to the cross-section information to form a plurality of shell layers. Next, foaming process is performed on the liquid forming material to form a foamy forming material. Next, the foamy forming material located within the corresponding shell layers is cured to form a plurality of foamy filling layers. Afterward, the shell layers and the foamy filling layers are alternately formed on the moving platform and stacked to form the three-dimensional structure. A three-dimensional printing apparatus adopting the method is also provided.

Description

technical field [0001] The present invention relates to a printing device and a printing method, and in particular to a three-dimensional printing device and a three-dimensional printing method. Background technique [0002] In recent years, with the increasing development of science and technology, many different methods for constructing physical three-dimensional (Three Dimensional (3D) models for short) have been proposed one after another by using additive manufacturing technology such as layer-by-layer construction model. Generally speaking, additive manufacturing technology converts the design data of a 3D model constructed by software such as Computer Aided Design (CAD) into multiple thin (quasi-two-dimensional) cross-sectional layers that are stacked continuously. At the same time, many technical means that can form multiple thin cross-sectional layers have also been gradually proposed. For example, the printing module of the printing device can generally move above...
