Design and Development of Large Format Additive Manufacturing Techniques

Abstract: This report discusses the creation of a large format additive manufacturing (LFAM) printer and initial test printing with the machine. A pellet-extruder head was attached to a computer numerical control (CNC) gantry. The team at the US Army Research and Development Center (ERDC) modified gantry arms to increase build height and designed electronic controls to allow for control of the printhead and the heated print bed. This report also covers print parameter optimization and print settings development.
