Abstract

This paper presents the optimization of the 3-D Hybrid Metal Printer. This printer, developed at Western Michigan University, offers a hybrid method to create finished functional metal parts using one setup. This 3-D metal printing method integrates an additive and subtractive manufacturing process. It uses a computer numerical controlled machine (CNC) and a method of welding called gas metal arc welding (GMAW). The additive process utilizes GMAW to deposit each layer of metal, then the subtractive process uses the CNC mill to machine the layer. The process is repeated multiple times until the part is complete. This technology has the potential to be brought into areas that do not have the resources readily available to create a part with common manufacturing methods. Optimizing the 3-D Hybrid Metal Printer process includes integrating a realtime scanning system and testing new materials. This scanning system can give instant feedback on the shape and geometry of the part to ensure constant consistency and uniformity throughout the additive and subtractive manufacturing process. With this system, the process and parts can be accurately verified and documented to meet required specifications for structure integrity and tolerances.
