Continuous Development of the 3D Hybrid Metal Printer & Printing Proces
Abstract
This research article presents the ongoing continuous improvements that are currently being applied and implemented with the 3-D Hybrid Metal Printer
located on Western Michigan University’s engineering campus. The 3-D Hybrid Metal Printer uniquely manufactures metal components with the use of a
patented process that integrates an additive and subtractive manufacturing method. This additive manufacturing method uses a form of bonding called gas
metal arc welding (GMAW). This deposits material along a predetermined and calculated path that matches the geometrical shape of the component being
manufactured. Once the first layer of material is deposited, the subtractive manufacturing method implements the use of a computer numerical controlled
machine (CNC) to machine the component. This process is repeated until the component has meet the required geometrical specifications. Improvements that
have recently been applied and are currently being used include an upgraded mounting configuration for the GMAW arm, a custom coolant reservoir with drip
tray, a 3-D scanning system, safety equipment with elevated safety procedures, and weld pattern configuration optimization. These improvements not only
decrease the time required to manufacture components, but also increases the sustainability of this patented technolog
