界定待藉由光固化制造的三度空间物体的支撑结构的方法及设备;METHOD AND EQUIPMENT FOR DEFINING A SUPPORTING STRUCTURE FOR A THREE-DIMENSIONAL OBJECT TO BE MADE THROUGH STEREOLITHOGRAPHY

摘要

本发明系一电脑实施方法，用于界定一藉由一光固化程序待制造的三度空间物体(1)的支撑结构(2)，包含以下的操作：界定一三度空间物体(1)的待支撑的第一表面(3)以及一面对第一表面(3)的第二表面(4)；界定表面(3、4)之间的细长的支撑元件(5)；界定支撑元件(5)的成对；对于每一对支撑元件(5)，界定一连接该对的两个支撑元件(5)的细长的加强元件(6)。支撑元件(4)的成对的界定包含以下操作：界定每一支撑元件(5)的一基准点(7)；界定一具有作为顶点的基准点(7)的连通非循环图形(8)；对于图形每一边(9)，界定包含两个对应于边(9)的端点的一对支撑元件(5)。支撑元件(5)的成对的界定包含进一步的操作：对于每一具有连通非循环图形(8)的顺序1的顶点，界定一额外对的支撑元件，额外对包含一对应于具有顺序1的顶点的第一支撑元件(5)以及不藉由任何边(9)连接至第一支撑元件(5)的第二支撑元件(5)。; defining elongated supporting elements (5) between the surfaces (3, 4); defining pairs of supporting elements (5); for each pair of supporting elements (5), defining an elongated reinforcing element (6) connecting the two supporting elements (5) of the pair. The definition of the pairs of supporting elements (5) comprises the following operations: defining a reference point (7) of each supporting element (5); defining a connected acyclic graph (8) having as vertices the reference points (7); for each edge (9) of the graph, defining one pair of supporting elements comprising the two supporting elements (5) corresponding to the ends of the edge (9). The definition of the pairs of supporting elements (5) comprises the further operation of defining an additional pair of supporting elements for each vertex having order 1 of the connected acyclic graph (8), the additional pair comprising a first supporting element (5) corresponding to the vertex having order 1 and a second supporting element (5) not connected to the first supporting element (5) through any edge (9).
