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.

Dependent claims

A computer-implemented method comprising:

receiving a three-dimensional model of an object to be created by a three-dimensional extrusion printer that includes a tool-head that will create at least a portion of the object;
determining a plurality of infill structures in a slice of the object, the infill structures including a first infill structure, one or more second infill structures that each are not adjacent to the first infill structure in the slice, and a third infill structure that is adjacent to the first infill structure in the slice;
and
determining a path for the tool-head to create each of the plurality of infill structures in the slice of the object including:
determining a first portion of the path to cause the tool-head to deposit material forming the first infill structure during a first time period;
determining a second portion of the path to cause the tool-head to deposit material forming each of the second infill structures that are not adjacent to the first infill structure during a second time period after the first time period;
and
determining a third portion of the path to cause the tool-head to deposit material forming the third infill structure that is adjacent to the first infill structure during a third time period after the second time period, wherein the second time period is determined to allow the first infill structure to cool before deposition of the third infill structure by the tool-head of the three-dimensional extrusion printer;
determining a material that the three-dimensional extrusion printer will use to create the object;
determining a cooling time for the material using a first temperature at which the material will be deposited and at least one second temperature of an area in which the material will be deposited;
and
determining a duration for the second time period using the cooling time for the material.

wherein determining the path for the tool-head to create each of the plurality of infill structures comprises:
determining, for all infill structures in the plurality of infill structures for which a portion of the path has not been determined, a respective portion of the path during a period of time separated in time from the time periods for the infill structures adjacent to the respective infill structure to allow the adjacent infill structures to cool before deposition of the respective infill structure.
