BUILD PATH OPTIMIZATION USING GROUPED TRIANGES OF A POLYGONAL MESH
The strength of a bond between two adjacent layers of a three-dimensional print is weakened by initiating fabrication of a top layer at a height greater than the processing height for the print. This technique may be used in particular at the interface between a raft or other support and an object being fabricated, after which the printing process may return to a regular process height for additional layers used to fabricate the remainder of the object.
