Welcome to CFA Design, a Phoenix-based prototyping firm specializing in 3D CNC machining.  Whether you are a designer, inventor, or engineer, CFA Design can prototype your CAD designs.  We enable you to create large physical models of your design for fit, form, and function review, for client feedback, or for your own iterative design processes. CFA Design specializes in creating short-run molds for casting prototype plastic parts. Unlike the typical SLA pattern & silicon mold process, CFA Design directly machines low-cost molds using a high-speed CNC mill, thereby bypassing the pattern creation stage. Patterns and composite molds for vacuum resin infusion, VARTM, concrete, rotomolding, rotational molding, rubber molds, and urethane parts.
