Bambu Lab TPU 85A Lime Green 1kg

Bambu Lab TPU 85A Lime Green 1kg

Bambu Lab TPU 85A is the softest TPU filament in the Bambu Lab range and ranks among the softest materials available for FDM 3D printing. This variant in a rich Lime Green color is the perfect choice for functional parts that must be highly flexible, durable and shock-absorbing.

With a Shore hardness of 85A, the filament is significantly softer than common TPU 95A and allows printing of parts that can be easily squeezed, bent and stretched – while maintaining their shape even after repeated stress.

Warning: TPU 85A is not suitable for feeding through long PTFE tubes or for AMS/AMS Lite. For reliable printing, direct feeding into the extruder is recommended.

Main advantages and use

• Extreme flexibility (Shore 85A) Ideal for parts that must be soft, flexible and compressible – for example, shock absorbers, padding or flexible joints.
• High wear resistance The material is designed for long-term mechanical stress – frequent bending, compressing or twisting without cracking.
• Excellent shock and vibration damping Greatly suited for protective covers, bumpers, damping pads and elements where energy absorption is key.
• Good layer adhesion Correctly set printing provides strong bonds between layers, which is crucial for flexible parts.
• Official Bambu Lab material The filament is optimized for Bambu Lab X1, P1, A1 / H2D printers (with direct feeding and recommended settings), including preset profiles in Bambu Studio (or with adjustment of settings for 85A).

Recommended use

Bambu Lab TPU 85A Lime Green is particularly suitable for:

• Protective covers and cases (phones, electronics, tools)
• Soft grips and handles (sports equipment, tools, controllers)
• Shock and vibration absorbers, stops, silent blocks
• Seals and flexible couplings
• Orthotics, bandages, soft protectors (where TPU use is appropriate)
• Fidget toys, squishy models and decorations

The Lime Green color is bold, highly visible and suitable for functional prototypes, sports or design parts where both function and appearance are important.

Printing recommendations

Specific values may vary slightly depending on the printer and environment, but generally recommended are:

• Nozzle temperature: approximately 220–240 °C
• Bed temperature: approx. 25–45 °C (depending on bed type and adhesion)
• Print speed: lower than for PLA/PETG, focus on consistent material flow
• Direct drive: for TPU 85A is almost a necessity
• Disabling or limiting Flow Dynamics Calibration when using official TPU 85A profiles, if recommended by the manufacturer

For best results, it is recommended to thoroughly dry the filament before printing, as TPU is hygroscopic and moisture can lead to bubbles, stringing and poor surface quality.

Material properties

• Material type: TPU (thermoplastic polyurethane)
• Shore hardness: 85A
• Very high flexibility and elasticity
• High elongation at break – suitable for parts subjected to bending and stretching
• High resistance to abrasion and wear
• Good chemical resistance to common lubricants and oils (depending on specific conditions)

Compatibility with Bambu Lab printers

• Suitable for Bambu Lab printers with a direct extruder (e.g. X1, P1 series, A1/H2D with appropriate configuration).
• Not suitable for feeding through AMS/AMS Lite – the filament is too soft and may jam in long guide paths.
• It is recommended to use direct feeding into the extruder without long PTFE tubes.

Packaging and handling

• Fill weight: 1 kg TPU 85A
• Diameter: 1,75 mm (high dimensional accuracy)
• Supplied on a high-temperature resistant reusable Bambu Lab spool
• Filament is vacuum-packed for protection against moisture.

For long-term storage, keep the filament dry, ideally in a sealable box or vacuum bag with silica gel.

Summary

Bambu Lab TPU 85A Lime Green is a top-tier flexible filament designed for demanding applications where a combination of softness, flexibility and high durability is needed. Thanks to optimization for Bambu Lab printers and excellent material consistency, it is a great choice for professional and advanced home users who want to reliably print soft functional parts in an attractive green color.
