The next approach was to make a mold with the 3D printer and pour the chosen polyurethane resin in, but a simple hollow mold didn’t work because the polyurethane heats as it cures. The combined ...

Is it possible to create a shoe that can handle all that, using a 3D printer? [RCLifeOn] discovered ... one shoe was printed in thermoplastic polyurethane, the other in Ninjaflex.

To utilize this property, the team designed a composite structure using dual-nozzle fused deposition modeling (FDM) 3D printing to directionally align graphene within a thermoplastic polyurethane (TPU ...
