1. A method of forming a three-dimensional object using an extrusion-based layered deposition system, the method comprising:
- generating a build path for building a layer of the three-dimensional object, wherein the build path defines a void region;
generating at least one intermediate path in the void region;
determining dimensions of the void region based at least in part on the at least one generated intermediate path; and
generating a remnant path in the void region based at least in part on the at least one intermediate path, wherein the remnant path comprises deposition rates that are configured to vary based on the determined dimensions of the void region.

Abstract
A method of forming a three-dimensional object using an extrusion-based layered deposition system, the method comprising generating a build path for building a layer of the three-dimensional object, where the build path defines a void region. The method further comprising generating at least one intermediate path in the void region, and generating a remnant path based at least in part on the at least one intermediate path.

15. A method of forming a three-dimensional object using an extrusion-based layered deposition system, the method comprising:
-
generating a build path for building a layer of the three-dimensional object with a plurality of first deposition roads based on a first road width resolution, wherein the build path defines a void region having dimensions that are smaller than the first road width resolution along at least one axis; and generating a remnant path in the void region for filling at least pan of a cavity corresponding to the defined void region with a second deposition road based on deposition rates that are configured to vary based on the dimensions of the void region. - View Dependent Claims (16, 17, 18, 19)
