Abstract: A computer system for part production using flow infill design receives a computer-aided design file that describes physical dimensions of a target object (120). The computer system identifies a physical boundary portion (300) of the target object within the CAD file. The computer system generates a first tool path to additively manufacture the physical boundary portion (300). Additionally, the computer system sends instructions to a computer system in communication with a dispenser (130) that cause the dispenser to implement the first tool path while dispensing a boundary material. Further, the computer system generates a command to dispense the coreactive infill material (310) within the physical boundary portion.

Abstract: A computer system (110) for part production using additive design receives a computer-aided design (CAD) file that describes physical dimensions of a target object (120). The computer system (110) identifies a physical boundary portion (300) of the target object within the CAD file. The computer system determines a target flow rate to infill the physical boundary portion (300) with the infill material.
