Three-dimensional printing
First Claim
1. A computer-implemented method comprising:
- receiving a three-dimensional model of a solid object for creation by a three-dimensional extrusion printer;
determining a hollow shell for the three-dimensional model that includes a plurality of interior surfaces;
determining, for each of the plurality of interior surfaces, an angle of the respective interior surface;
determining, for each of the interior surfaces that have an angle that satisfies a threshold angle, an infill structure for an interior structure to be located inside a modified object and extending through each layer of the three-dimensional model up to the respective interior surface, wherein the modified object is the same type of object as the solid object with at least one aperture;
skipping, for each of the interior surfaces that have an angle that does not satisfy the threshold angle, generation of any infill structure; and
generating data that represents each of the determined infill structures for use by the three-dimensional extrusion printer with the three-dimensional model to create the modified object.

Abstract
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for working with three-dimensional object models for printing. One of the methods includes determining a plurality of infill structures in a slice of an object; and determining a path for the tool-head to create the plurality of infill structures including: determining a first portion of the path for deposition of a first infill structure during a first time period; determining a second portion of the path for deposition of one or more second infill structures that are not adjacent to the first infill structure during a second time period; and determining a third portion of the path for deposition of a third infill structure that is adjacent to the first infill structure, wherein the second time period is determined to allow the first infill structure to cool before deposition of the third infill structure.
