Filament BambuLab TPU for AMS 1.75 mm 1 kg — Yellow

Filament BambuLab TPU for AMS 1.75 mm 1 kg — Yellow is a flexible thermoplastic polyurethane filament formulated for FDM/FFF 3D printing with AMS-compatible multi-material systems. With a 1.75 mm diameter and a 1 kg spool, this TPU is intended for producing elastic, impact-resistant prints such as wearable parts, seals and functional prototypes. The filament is presented in a high-visibility yellow and is compatible with printers that accept 1.75 mm TPU in multi-material workflows.

Advantages

This TPU filament provides a balance of elasticity and strength appropriate for flexible end-use parts and prototypes. Its consistent 1.75 mm diameter supports reliable feeding in AMS-style feeders and multi-material setups, reducing print interruptions. The material exhibits good layer adhesion for durable prints and sufficient abrasion resistance for parts subject to wear. The spool format and packaging are designed for straightforward handling and integration into typical FDM workflows.

Suitable for

• Elastic functional prototypes and snap-fit parts
• Wearable items and soft accessories
• Seals, gaskets and shock-absorbing mounts
• Flexible fixtures and grips
• Multi-material prints requiring a flexible component

How to use

Load the filament onto an AMS-compatible feeder or direct-drive system designed for flexible materials, ensuring the filament path is guided and free of sharp bends. Use printer settings tuned for TPU: moderate print speed, reduced retraction, and a heated bed if recommended by your printer or profile. Adjust print temperature and speed based on the printer and the specific TPU formulation to achieve optimal layer bonding and surface finish. Store the spool in a dry environment or sealed with desiccant when not in use to maintain filament quality.

Usage recommendations

For best results, start with conservative settings—lower speeds and minimal retraction—and iterate to optimize dimensional accuracy and surface quality. Use a direct-drive or well-guided Bowden path to minimize filament buckling. When printing multi-material parts, account for differences in printing temperature and cooling between TPU and rigid materials to avoid deformation of flexible sections.
