Filament BambuLab TPU for AMS 1.75 mm 1 kg — BambuLab flexible print material, red

BambuLab TPU for AMS is a 1.75 mm flexible filament supplied on a 1 kg spool and formulated for use with BambuLab AMS-compatible systems and other setups that support TPU. The material delivers rubber-like elasticity and good abrasion resistance, making it suitable for parts that require flexibility, impact absorption, or repeated deformation. The filament comes in a red color that can be used for visible functional elements or for aesthetic accents in printed assemblies.

Advantages

TPU for AMS offers a balance of elasticity and durability, providing flexible prints that return to shape after bending. The filament is formulated to flow consistently through Bowden and direct-drive extruders that support flexible materials, reducing the risk of jams when used with appropriate printer settings. Its abrasion resistance improves longevity in moving or contact surfaces, while the 1 kg spool size supports medium-length print runs without frequent changes.

Suitable for

• Flexible prototypes and functional parts such as hinges and bellows
• Wearables and straps where comfort and stretch are needed
• Seals, gaskets and shock-absorbing components
• Grips, bumpers and protective covers
• Visual or safety markings requiring red-colored flexible parts

Key specifications

• Diameter: 1.75 mm
• Spool weight: 1 kg of filament
• Material type: Thermoplastic polyurethane (TPU), flexible
• Color: Red
• Compatibility: Designed for AMS-compatible systems and printers capable of handling flexible filaments
• Mechanical properties: Elastic with abrasion resistance suitable for wearable and contact parts

How to use

Load the filament onto an AMS-compatible feeder or an equivalent filament path designed for flexible materials. Use a print nozzle and temperature settings recommended for TPU on your specific printer; typical extrusion temperatures for TPU filaments are lower than for some rigid filaments, and print speed should be reduced to ensure consistent feeding. Enable retraction settings appropriate for TPU or disable aggressive retraction to avoid jams. Apply a suitable print surface or adhesive to ensure first-layer adhesion for flexible parts. Allow printed parts to cool before removing them from the build plate to avoid deformation.

Usage recommendations

Store the filament in a dry environment or sealed container with desiccant to prevent moisture uptake. For best results, print at moderate speeds, use a compatible extruder path for flexible filaments, and test small calibration prints to adjust temperature, speed, and retraction before printing critical parts.
