BambuLab TPU 95A HF 1.75 mm 1 kg flexible filament for 3D printing — Yellow

BambuLab TPU 95A HF 1.75 mm is a flexible 3D printing filament supplied on a reusable 1 kg spool in yellow. With a Shore hardness of 95A, this thermoplastic polyurethane (TPU) filament balances flexibility and dimensional stability to produce durable, impact-resistant parts. It is formulated for FDM/FFF printers that support TPU materials and aims to deliver consistent extrusion, reliable layer adhesion, and good surface finish for flexible functional components and prototypes.

Advantages

The filament provides high flexibility combined with wear and tear resistance, enabling printed parts to flex without permanent deformation. Its 1.75 mm diameter and consistent roundness support steady feeding and extrusion on compatible hotends and direct-drive or Bowden setups. Layer bonding is optimized for flexible geometries, and the material exhibits resilience to repeated bending and compression. The reusable spool contributes to cleaner storage and easier handling.

Suitable for

• Wearable parts such as straps, bands, and flexible enclosures
• Gaskets, seals, and vibration-damping components
• Impact-resistant prototypes and protective covers
• Functional hinges, clips, and snap-fit assemblies

Key specifications

• Material: Thermoplastic polyurethane (TPU)
• Shore hardness: 95A
• Diameter: 1.75 mm
• Net weight: 1 kg on reusable spool
• Color: Yellow
• Suitable printing technology: FDM/FFF

How to use

Load the filament onto a compatible 3D printer configured for flexible materials. Use a nozzle and feeder system suitable for TPU; direct-drive extruders typically provide the most reliable feeding, though Bowden setups can work with reduced print speed and careful retraction settings. Set print temperatures and speeds according to your printer and hotend recommendations for TPU 95A, and calibrate retraction, printing temperature, and bed adhesion methods before producing critical parts. Ensure proper spool mounting to avoid tangling and maintain consistent filament tension during printing.

Usage recommendations

For best results, print at moderate speeds, minimize retraction distance to prevent filament grinding, and use a build surface or adhesive that improves first-layer adhesion for flexible parts. Store the filament in a dry environment or sealed container with desiccant to preserve printability and mechanical properties.
