Filamento flexível Polymaker PolyFlex TPU90 TPU 1,75mm 750g transparente PD02004

Polymaker PolyFlex TPU90 stands out as a flexible TPU filament with a Shore hardness of 90A, balancing elasticity with ease of printing. Unlike softer TPUs that can be difficult to extrude, this filament feeds reliably on most direct-drive and even some Bowden setups, while still delivering the rubber-like flexibility needed for impact-resistant parts, seals, and vibration dampeners.

Highlights

• Flexible TPU with 90A shore hardness for durable, rubber-like parts
• Excellent abrasion resistance and good layer adhesion
• Clear colour with high transparency for functional and aesthetic prints
• Vacuum-sealed packaging with desiccant to protect filament quality

In daily use

PolyFlex TPU90 prints at 210–230 °C with a bed temperature of 25–50 °C (or unheated). A slower print speed of 20–40 mm/s yields the best results, allowing the flexible filament to extrude consistently and bond between layers. The 1.75 mm diameter with ±0.05 mm tolerance ensures smooth feeding and reliable extrusion.
