Impact of thermoplastic polyurethane (TPU) as a plasticiser-free binder on additive manufacturing of magnesium alloys: A comparison with polypropylene-polyethylene copolymers

This study presents a breakthrough in screw-based material extrusion (SBME) of magnesium (Mg) alloys by introducing a plasticiser-free thermoplastic polyurethane (TPU) binder system that achieves a 70 vol% powder loading, the highest reported for material extrusion of any solid material. TPU perform...
