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

BambuLab TPU 95A HF 1.75 mm is a flexible thermoplastic polyurethane filament formulated for FDM/FFF 3D printers. Supplied on a 1 kg spool with 1.75 mm diameter, this TPU combines a relatively high Shore 95A hardness with an HF (high flow) formulation to deliver flexible yet dimensionally stable prints. It is intended for parts that require elasticity, abrasion resistance, and impact tolerance while maintaining good layer adhesion and printability on compatible printers and extruders.

Advantages

The HF formulation increases flowability for smoother extrusion at recommended print settings, reducing under-extrusion and improving surface quality on complex geometries. The Shore 95A hardness offers a balance between flexibility and stiffness, enabling elastic behavior without excessive deformation under load. The filament is wound on a standard 1 kg spool with consistent 1.75 mm diameter to help maintain stable feeding and predictable extrusion rates.

Suitable for

• Seals and gaskets that require elasticity and abrasion resistance
• Wearable prototypes and flexible enclosures
• Impact-resistant components, bumpers, and protective parts
• Functional prototypes where repeated deformation is expected

Key specifications

• Filament type: Thermoplastic polyurethane (TPU) with HF high-flow formulation
• Nominal diameter: 1.75 mm
• Spool weight: 1 kg
• Shore hardness: 95A
• Color: Blue

How to use

Load the filament into a compatible FDM/FFF printer with an extruder and nozzle suitable for flexible materials. Use a direct-drive or properly calibrated Bowden setup with a short, constrained filament path to minimize buckling. Print at temperatures and speeds recommended for TPU HF material by the printer or filament manufacturer, and enable retraction settings optimized for flexible filaments to avoid jams. Ensure bed adhesion through a suitable build surface or adhesive method; a heated bed is typically beneficial for dimensional stability.

Usage recommendations

Store the filament in a dry, cool environment and reseal the spool when not in use to prevent moisture uptake. Perform test prints to fine-tune temperature, speed, and retraction for your specific printer. For parts requiring maximal elasticity, avoid overly high infill or overly aggressive cooling settings that can reduce interlayer flexibility.
