Method of optimising the joints between layers in modelling or prototyping involving layer decomposition, and parts thus obtained

摘要

A method for optimizing the joints between layers in that portion thereof which is flush with the surface of a part obtained by means of computer-aided modeling or prototyping of the type involving layer decomposition, characterized in that the connecting profile of two successive layers is mathematically and numerically defined using an algorithm in which the surface of the joint ( 7 ) at the end zone close to the flush portion is always substantially normal {right arrow over (n to the plane tangential to the surface at the flush point.
