Bambu Lab TPU 85A 3D Printing Filament 1.75mm 1kg, Rose Beige, Reusable Spool Included

Bambu Lab TPU 85A is a high-performance 1.75mm 3D printing filament engineered for flexibility and durability. With a Shore hardness of 85A, this material offers a balance between elasticity and structural integrity, making it an excellent choice for functional 3D printed parts that require impact resistance and resilience. The filament is supplied on a reusable spool, which supports efficient material management and seamless integration with Bambu Lab 3D printer systems.

Advantages

The primary benefit of this TPU filament is its superior flexibility combined with high wear resistance and mechanical strength. It maintains consistent extrusion quality, which is essential for achieving precise dimensions in flexible prints. The inclusion of a reusable spool reduces waste and simplifies the reloading process, while the specific Rose Beige color provides a unique aesthetic finish for finished components. Its chemical resistance and ability to withstand repeated bending make it a reliable material for demanding engineering applications.

Suitable for

• Manufacturing flexible gaskets and seals
• Creating protective cases and bumpers for electronics
• Printing vibration-dampening components
• Developing flexible joints or hinges
• Producing impact-resistant prototypes

This filament may not be suitable for applications requiring high rigidity or extreme thermal stability, as TPU is inherently flexible and can soften at elevated temperatures. It is also not recommended for parts that require high-speed printing without proper calibration, as flexible materials can be prone to jamming if the printer's extrusion system is not optimized for soft filaments.

Key specifications

• Material: TPU (Thermoplastic Polyurethane)
• Shore Hardness: 85A
• Diameter: 1.75mm
• Weight: 1kg
• Color: Rose Beige
• Spool type: Reusable

How to use

To achieve optimal results, ensure the filament is dry before printing, as TPU is hygroscopic and can absorb moisture from the air. Load the filament into your 3D printer according to the manufacturer's guidelines, ensuring the path is clear to prevent buckling. Adjust your slicer settings to accommodate the flexible nature of the material, typically by reducing print speeds and ensuring the retraction settings are minimized to prevent clogging in the hotend.

What to consider before purchase

• Verify that your 3D printer's extruder is compatible with flexible filaments.
• Ensure your printer's build plate is clean to maintain proper adhesion.
• Consider the need for a filament dryer if you live in a high-humidity environment.
• Check the color requirements for your specific project.

Usage recommendations: For the best printing experience, store the filament in a sealed container with desiccant when not in use. Regularly clean your printer's nozzle and extruder gears to maintain consistent extrusion quality and prevent debris buildup.
