Polymaker PolyFlex TPU90 joustava TPU-filamentti 1,75 mm 750 g sinivihreä PD02005

With a Shore hardness of 90A and elongation at break exceeding 300%, this TPU filament delivers exceptional flexibility and impact resistance for demanding prints. The Polymaker PolyFlex TPU90 in Blue-Green combines a 1.75 mm diameter with a 750 g spool, ensuring consistent extrusion and reliable performance on any FDM printer.

Overview

Polymaker PolyFlex TPU90 is a premium thermoplastic polyurethane filament engineered for parts that require high elasticity, durability, and resistance to wear. Its 90A shore hardness strikes a balance between flexibility and structural integrity, making it ideal for functional prototypes, gaskets, protective cases, and vibration-dampening components. The filament is wound on a transparent spool with a neat, tangle-free winding, ensuring smooth feeding throughout the print.

What stands out

• High flexibility: >300% elongation at break absorbs shocks and returns to shape.
• Consistent diameter: ±0.05 mm tolerance prevents clogs and under-extrusion.
• Low warping and odor: prints reliably on open-frame printers with minimal fumes.
• Wide compatibility: works with most direct-drive and Bowden extruders when using moderate speeds.
• Vibrant Blue-Green colour: adds a professional finish to functional parts.
