Soft 3D printing of thermoplastic polyurethane: Preliminary study

Thermoplastic polyurethane (TPU) is a highly elastic linear polymer composed of soft segments, usually flexible polyester or polyethers. It is widely used in 3D printing technologies using FFF (Fused Filament Fabrication), SLS (Selective Laser Sintering) or inkjet printing. Among these options, FFF...
