Filament BambuLab TPU for AMS 1.75 mm 1 kg spool — Gray (BambuLab)

Filament BambuLab TPU for AMS 1.75 mm 1 kg spool — Gray is a flexible thermoplastic polyurethane filament formulated for compatibility with AMS-equipped BambuLab systems and other printers using 1.75 mm extruders. Supplied on a reusable 1 kg spool in a neutral gray color, this TPU filament is intended for producing elastic, impact-resistant parts and functional prototypes that require flexibility, good layer adhesion and abrasion resistance.

Advantages

This TPU filament offers reliable flexibility and consistent diameter for smooth feeding in AMS setups and standard 1.75 mm extruders. It provides good elastic recovery and resistance to wear, enabling durable prints for parts that undergo repeated deformation. The reusable spool reduces waste and supports multiple print sessions with minimal spool handling disruption. Gray color provides a neutral finish suitable for functional components and prototypes.

Suitable for

• Flexible functional prototypes and hinges
• Seals, gaskets and vibration dampers
• Wearable components and soft-touch grips
• Impact-resistant machine parts and protective covers
• Multi-material assemblies with rigid and elastic sections

Key specifications

• Material type: Thermoplastic polyurethane (TPU)
• Diameter: 1.75 mm nominal
• Net filament weight: 1 kg on a reusable spool
• Color: Gray
• Compatibility: Designed for AMS-compatible systems and standard 1.75 mm extruders
• Application properties: Flexible, abrasion-resistant, impact-resistant

How to use

Load the spool into an AMS module or a printer filament holder compatible with 1.75 mm filament, ensuring the filament path is free of sharp bends and obstructions. Set printer parameters recommended for TPU: lower print speed compared to rigid filaments, direct or AMS feeding optimized for flexible materials, moderate nozzle temperature and reduced retraction to prevent jamming. Print on a build surface that improves adhesion for TPU and consider using a brim or skirt for first-layer stability. Allow parts to cool slowly to preserve elasticity and dimensional stability.

Usage recommendations

For best results, use print speeds in the lower range, adjust retraction settings to minimal values, and maintain a stable filament feed path. Store the spool in a dry environment or sealed bag with desiccant to preserve material properties. Test small calibration prints to fine-tune temperatures and flow before manufacturing critical parts.
