Bambu Lab TPU Filament Refill 1.75mm 1kg Black for AMS

The Bambu Lab TPU Filament Refill is a high-performance 1.75mm thermoplastic polyurethane material designed specifically for demanding 3D printing applications. This 1kg black filament is engineered to provide exceptional flexibility, durability, and robust layer adhesion, making it an ideal choice for functional parts that require elasticity. The refill format is designed to be used with reusable spools, promoting a more sustainable printing workflow by reducing plastic waste while maintaining full compatibility with the Bambu Lab AMS system for seamless multi-material printing.

Advantages

This TPU filament offers superior mechanical properties, ensuring that printed objects can withstand significant stress and deformation without breaking. Its optimized formulation allows for consistent extrusion and reliable performance, which is critical when printing flexible geometries. By utilizing the refill system, users can easily swap materials while minimizing environmental impact. The material is specifically tuned for high-speed printing environments, providing a balance between print quality and production efficiency while ensuring excellent bed adhesion and minimal warping.

Suitable for

• Manufacturing flexible gaskets and seals
• Creating protective cases and bumpers
• Printing elastic components for robotics
• Developing custom footwear or wearable prototypes
• Producing vibration-dampening mounts

When it may not be suitable

This filament may not be suitable for projects requiring extreme rigidity or high-temperature resistance, as TPU is inherently flexible and will soften under significant heat. Additionally, it is not recommended for applications requiring high-detail aesthetic finishes where surface texture must be perfectly smooth, as flexible materials can be more challenging to post-process than rigid plastics like PLA.

Key specifications

• Material: Thermoplastic Polyurethane (TPU)
• Diameter: 1.75mm
• Weight: 1kg
• Color: Black
• Compatibility: Bambu Lab AMS system

How to use

To use the refill, place it onto a compatible reusable spool by following the manufacturer's assembly instructions. Ensure the filament is properly secured before loading it into the printer. When printing with TPU, it is recommended to use the specific material profile provided in the slicer software to ensure optimal temperature and speed settings. Feed the filament through the AMS or directly into the extruder, ensuring the path is clear of any obstructions to prevent binding during the printing process.

What to consider before purchase

• Ensure your 3D printer is compatible with flexible filaments
• Verify that you have a reusable spool available for the refill
• Check if your specific print model requires the mechanical properties of TPU
• Confirm that your printer's extruder setup is suitable for flexible materials

Usage recommendations

Store the filament in a cool, dry place and use a desiccant to prevent moisture absorption, as TPU is hygroscopic and can degrade in quality if exposed to humidity for extended periods.
