Filament BambuLab TPU for AMS 1.75 mm 1 kg with reusable spool — Blue

Filament BambuLab TPU for AMS 1.75 mm 1 kg with reusable spool — Blue is a flexible thermoplastic polyurethane filament designed for use with AMS filament management systems and 1.75 mm direct-drive or Bowden printers that support flexible materials. The material combines elasticity and impact resistance to produce functional prints such as gaskets, protective components, wearable parts and flexible prototypes. The filament is supplied on a reusable spool to simplify storage and reduce waste while maintaining consistent feed into AMS-equipped setups.

Advantages

The TPU filament provides high elasticity and good tear resistance while maintaining dimensional stability during printing. Its formulation is suitable for printing flexible, shock-absorbing parts with smooth surface finish and reliable layer adhesion. The reusable spool supports tidy filament handling and makes it easier to integrate into automated multi-spool systems. Color consistency in Blue ensures predictable visual results for parts where appearance matters.

Suitable for

• Sealing elements and gaskets requiring elasticity and compression recovery
• Protective bumpers, mounts and shock-absorbing components
• Wearable items such as straps, flexible enclosures and ergonomic grips
• Functional prototypes that need flexible behaviour and impact resistance

Key specifications

• Material type: Thermoplastic polyurethane (TPU) with flexible properties
• Nominal diameter: 1.75 mm for compatibility with standard extruders
• Net weight: 1 kg of filament per spool
• Color: Blue for visual consistency in prints
• Packaging: Reusable spool suitable for AMS filament management

How to use

Load the filament into a printer or AMS system configured for 1.75 mm flexible filaments following the printer manufacturer's guidance for TPU. Use a print temperature and bed setup recommended for TPU materials, and adjust print speed, retraction and cooling to reduce stringing and improve surface finish. Ensure the filament path is constrained and guided to prevent buckling in the feed mechanism. After printing, allow printed parts to cool before flexing or installing to ensure accurate dimensions.

Usage recommendations

For best results, print TPU at moderate speeds with reduced retraction distance, maintain a stable extrusion temperature as recommended by your printer or material settings, and use a direct drive or guided filament path when possible. Store the reusable spool in a dry environment or sealed container with desiccant to preserve material properties over time.
