1. A method for fabricating a part, the method comprising: creating a toolpath for an additive metal wire deposition machine to fabricate the part using additive metal wire deposition, including: exporting CAD defined 3-D geometry of the part to a slicing module; slicing the 3-D geometry of the part and creating a set of 2-D patterns representing the 3-D geometry of the part, wherein the set of 2-D patterns are a set of boundary contours; generating vector code from the set of 2-D patterns, wherein the vector code comprises contour data that defines the toolpath; and translating the vector code to machine code configured to execute in the additive metal wire deposition machine; executing the machine code in the additive metal wire deposition machine; and fabricating the part by additive metal wire deposition following the toolpath, using the machine code executed by the additive metal wire deposition machine.
