Comparison of injection molding and 3D printing costs. It is assumed that the injection mold costs $5000 and the cost per part, exclusive of mold-amortization, is 20¢. Total cost per molded part, including mold amortization declines with volume, while 3D-printed part cost is constant at an assumed 70¢. GOING AFTER INJECTION MOLDING According to Bentz,…
