Patent Images
1. A computer-implemented method for generating data for a support structure to be built with a deposition-based digital manufacturing system, the method comprising:
- providing a boundary polygon of a layer of the support structure;
generating a convex hull polygon based on the boundary polygon;
offsetting the convex hull polygon inward;
offsetting the boundary polygon outward; and
generating an intersection boundary polygon based at least in part on the offset boundary polygon and the offset convex hull polygon.

Abstract
A method for generating data for a support structure to be built with a deposition-based digital manufacturing system, the method comprising generating a convex hull polygon based on a boundary polygon of a layer of the support structure, offsetting the convex hull polygon inward, offsetting the boundary polygon outward, and generating an intersection boundary polygon based at least in part on the offset boundary polygon and the offset convex hull polygon.
