METHOD OF OPTIMISING THE JOINTS BETWEEN LAYERS IN MODELLING OR PROTOTYPING INVOLVING LAYER DECOMPOSITION, AND PARTS THUS OBTAINED

摘要

In a method for optimizing the joints between layers along portions of the layers which are flush with the surface of a part obtained by computer-aided modeling or prototyping involving layer decomposition, the connecting profile of two successive layers is mathematically and numerically defined using an algorithm in which the surface of the joint at the end zone adjacent to the flush portions is always substantially normal to the plane tangential to the surface of the part along the flush portions.
