Polymaker PolyFlex TPU90 flexibel TPU filament 1,75 mm 750 g grijs PD02003

Flexible TPU filament with 90A shore hardness, engineered for durable, elastic 3D printed parts. Its high flexibility and abrasion resistance make it ideal for functional prototypes, wearables, and seals.

Advantages

Excellent layer adhesion and elongation at break over 300% deliver tough, impact-resistant prints. The 1.75 mm diameter with ±0.05 mm tolerance ensures consistent extrusion and reliable performance on FDM printers.

Suitable for

• Flexible parts and functional components
• Wearables and seals
• Prototypes requiring elasticity
