System for rapid object production using additive infill design

A computer system for part production using additive infill design, comprising:

• one or more processors;
• and
• one or more computer-readable media having stored thereon executable instructions that when executed by the one or more processors configure the computer system to perform at least the following:
• receive a computer-aided design (CAD) file that describes physical dimensions of a target object;
• identify a physical boundary portion of the target object within the CAD file, wherein the physical boundary portion comprises a portion of the target object that encloses infill material;
• detect, with a computer vision system, a pre-existing physical boundary portion, wherein the computer vision system provides data to match the pre-existing physical boundary portion with the physical boundary portion of the target object within the CAD file, and wherein the computer vision system utilizes the CAD file to identify the pre-existing physical boundary portion based on the matching;
• determine a target flow rate to infill the physical boundary portion with the infill material;
• generate a first tool path to flow the infill material into the physical boundary portion, wherein:
• the infill material comprises a coreactive material, and
• the infill material comprises a mixture of two different materials and a volume mix ratio of the mixture of the two different materials is dynamically varied as a gradient during movement of a dispenser over the first tool path, as a function of spatial position along the first tool path, such that the mixture dispensed at different spatial positions along the first tool path comprises different respective mix ratios;
• send instructions to the dispenser that cause the dispenser to implement the first tool path while flowing the infill material into the physical boundary portion;
• generate a second tool path to additively manufacture the physical boundary portion;
• and
• send instructions to the computer system in communication with another dispenser that cause the other dispenser to implement the second tool path while flowing boundary material to form the physical boundary portion, wherein the second tool path and the first tool path are implemented simultaneously.
