Abstract: A continuous filament additive manufacturing machine for building a part by laying down a continuous mono-filament or composite filament material layer by layer on a tool or substrate. The machine includes a system, such as a robot, operable to move in at least three degrees of freedom, and a placement module coupled to the system and being configured to deposit the continuous filament material. The placement module includes a guide for guiding the material to the part, a heat source for pre-heating the material as it is being deposited from the placement module and a compaction device for compacting the material as it is being deposited from the placement module. The compaction device includes an ultrasonic horn that is ultrasonically vibrated to melt or flow the material and cause the material to fuse and be compacted to the tool or substrate.

Abstract: A method may include providing the design inputs to a first software package and a second software package, receiving one or more first instructions from the first software package and one or more second instructions from the second software package, generating one or more third instructions based, at least in part, on the one or more first instructions or the one or more second instructions, providing the one or more first instructions, the one or more second instructions, and/or the one or more third instructions to the first software package and/or the second software package, receiving a first list of executable instructions and a second list of executable instructions from the first software package and the second software package, respectively, and merging the first list of executable instructions and the second list of executable instructions to generate an integrated list of executable instructions.
