Three-dimensional printing apparatus and method for three-dimensional printing
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.
