Filament BambuLab TPU 95A HF 1.75 mm 1 kg — flexible 3D printing filament, Red

BambuLab TPU 95A HF 1.75 mm is a flexible thermoplastic polyurethane filament supplied on a 1 kg spool in red. The material has a Shore hardness of 95A and a high-flow (HF) formulation designed to improve extrusion consistency for FDM/FFF 3D printers that accept 1.75 mm filament. This filament combines elasticity, abrasion resistance and dimensional stability to produce flexible functional parts such as gaskets, seals, wearable components and prototypes that require both resilience and surface quality.

Advantages

The HF formulation promotes smoother flow through the hotend, reducing under-extrusion and improving layer adhesion when printing flexible geometries. With Shore 95A hardness, the filament provides a balance between flexibility and stiffness for parts that must bend while retaining shape. The red color offers consistent pigmentation across prints, and the 1 kg spool size supports extended printing runs without frequent spool changes.

Suitable for

• Flexible functional prototypes and snap-fit parts
• Gaskets, seals and vibration-damping components
• Wearable items and soft grips
• Small-scale production of flexible end-use parts

Key specifications

• Material: Thermoplastic polyurethane (TPU), high-flow formulation
• Shore hardness: 95A
• Filament diameter: 1.75 mm
• Spool weight: 1 kg
• Color: Red
• Compatibility: FDM/FFF 3D printers supporting flexible filaments and 1.75 mm diameter

How to use

Load the filament into a 3D printer configured for flexible materials and 1.75 mm filament diameter. Use a direct drive or recommended printer settings for flexible filaments to minimize filament path length and avoid buckling. Adjust print temperature, print speed and retraction settings according to printer manufacturer or filament supplier guidance to achieve consistent extrusion and good layer bonding. Allow prints to cool sufficiently before post-processing to maintain dimensional stability.

Usage recommendations

For optimal results, print at moderate speeds with reduced retraction and consider a direct-drive extruder or a guided filament path on Bowden setups. Store the filament in a dry environment or sealed container with desiccant to prevent moisture uptake that can affect print quality and extrusion consistency.
