Abstract: An additive manufacturing tool configured to couple to a spindle of a CNC machine, comprises a plurality of drive wheels movable between an engaged position wherein they compress filament from a filament source against a drive disc and a disengaged position wherein they are spaced apart from the filament, and a delivery assembly including a heating element and a nozzle having an outlet opening. When the plurality of drive wheels are in the engaged position and the drive disc is rotated, the filament is drawn into the tool from the filament source and routed around the drive disc to the nozzle, where heat transferred from the heating element to the nozzle melts the filament so that the filament flows through the outlet opening.

Abstract: An interchangeable unit adapted to couple to a computer numerical control (“CNC”) machine is disclosed comprising a holder that couples to a spindle of the CNC machine, a controller, wherein said controller is configured to receive the rotational speed of the spindle as an input, and a material processing unit, wherein said material processing unit executes a first function in response to a first rotational speed range of the spindle and executes a second function in response to a second rotational speed range of the spindle.
