TPU
TPU (Thermoplastic Polyurethane) is a flexible polymer that combines plastic toughness with rubber elasticity.
It’s widely used for phone cases, gaskets, seals, and wearable parts.
Shore hardness: 95A
Density: ~1.20 g/cm³
Glass transition temperature (Tg): −50 °C
Nozzle temperature: 210–230 °C
Bed temperature: 40–60 °C (Not necessary on pei)
Speed: Slow (20–40 mm/s) to prevent filament buckling.
Direct drive extruder preferred: Bowden setups struggle with flexible filaments.
Ventilation: Minimal fumes, safe to print indoors.
