METHOD FOR SETTING A SHAPING ANGLE FOR A THREE-DIMENSIONAL SHAPED PRODUCT

摘要

It is the objective to select shaping angles for three-dimensional shaping whereby the support section is either unnecessary or can be reduced to an absolute minimum. This objective is achieved by a method for setting shaping angles in a shaping method for a three-dimensional shaped product (1) by lamination, irradiation-based sintering and cutting, when undercut regions (2) are present, the method comprising the following steps by a CAD/CAM system: 1. a model for the three-dimensional shaped product (1) is set; (2) a standard of undercut angle is selected; (3) the model is rotated in angle units; (4) calculation is made of the total projected area on the horizontal plane of the undercut regions (2') among the undercut regions (2) whose angles crossing the horizontal plane are smaller angles than the standard of undercut angle; (5) selection is made of a rotation angle such that the total area is smallest or a prescribed standard value is reached.
