Abstract Scope |
Additive manufacturing (AM) is often regarded as a sustainable manufacturing process because it is known for its ability to reduce material waste. But as the scale of AM processes increase, the amount of waste generated by large format AM (LFAM) processes increases accordingly. Additionally, LFAM typically depends on secondary mechanical shaping techniques, such as machining, creating additional waste streams. These “waste” materials can be a valuable resource if they are determined to be a viable secondary LFAM feedstock material. This study investigates the potential for using recycled carbon-fiber reinforced polycarbonate (CF-PC) as a feedstock for the Big Area Additive Manufacturing (BAAM) system. The CF-PC material was mechanically recycled then re-pelletized. The mass flow rate and rheological behavior of the recycled materials were investigated to quantify the change in extrusion behavior. |
