Abstract: A system is disclosed for use in additively manufacturing a structure. The system may include an additive manufacturing machine, a memory having computer-executable instructions stored thereon, and a processor. The processor may be configured to execute the computer-executable instructions to determine if a tool path to be followed by the additive manufacturing machine during manufacture of the structure is located in free-space or on top of another tool path. When the tool path is located in free-space, the processor may be further configured to execute the computer-executable instructions to make a determination regarding a curvature of the tool path, and to selectively cause the additive manufacturing machine to fabricate a support for the tool path based on the determination.

Abstract: A system is disclosed for use in additively manufacturing a structure. The system may include an additive manufacturing machine, a memory having computer-executable instructions stored thereon, and a processor. The processor may be configured to execute the computer-executable instructions to cause the additive manufacturing machine to discharge a path of composite material. The processor may also be configured to execute the computer-executable instructions to make a comparison of an actual discharge location of the path of composite material to a desired discharge location, and to selectively cause the additive manufacturing machine to abort fabrication of the structure or to adjust discharge parameters based on the comparison.

Abstract: A system is disclosed for use in additively manufacturing a structure. The system may include an additive manufacturing machine, a memory having computer-executable instructions stored thereon, and a processor. The processor may be configured to execute the computer-executable instructions to determine a characteristic of an existing point to be used as an anchor for a path of composite material discharged by the additive manufacturing machine. The processor may also be configured to execute the computer-executable instructions to selectively cause the additive manufacturing machine to discharge the path of composite material with a variable ratio of matrix-to-fiber at the existing point that is based on the characteristic.
