Bambu Lab TPU 90A Crystal Blue 1kg

Bambu Lab TPU 90A Crystal Blue is a professional TPU filament with Shore 90A hardness, combining high flexibility, wear resistance, and very good dimensional accuracy. The semi-transparent blue color Crystal Blue lets light through and creates an impressive "crystal" effect – ideal for both design and functional parts.

Key Features

• Shore 90A Hardness – a balanced ratio between flexibility and dimensional stability, suitable for functional parts.
• High Elasticity – elongation at break over 600% (in XY plane) for repeated bending and squeezing without cracking.
• Impact and Abrasion Resistance – ideal for parts exposed to repeated stress (soles, tires, shock absorbers).
• Semi-transparent Crystal Blue Color – attractive translucent appearance, suitable for light effects, covers, packaging, or decorative elements.
• Optimized for Bambu Lab – ready-to-use print profiles in Bambu Studio, reliable operation on P, X, A, and H series printers (for TPU 90A).
• AMS Compatible – low feeding resistance and suitable winding on the original spool for multi-material printing.
• Possibility of combination with PLA and PETG* – TPU 90A can be joined with rigid materials in multi-material mode using "beam interlocking" (on compatible dual-nozzle systems, e.g., Bambu Lab H2C/H2D).

* The multi-material printing feature with PLA/PETG is supported for TPU 90A on selected dual-nozzle systems, not for TPU 85A.

Recommended Use

TPU 90A Crystal Blue is particularly suitable for:

• Protective Elements – bumpers, dampers, spacers, anti-vibration pads.
• Footwear and Textile Accessories – soles, insoles, flexible segments of wearable parts.
• RC and Hobby Parts – tires for RC models, drone bumpers, camera mounts.
• Covers and Cases – electronics packaging, phone covers, grips, and tool handles.
• Design Translucent Parts – light covers, lamps, decorations benefiting from the translucent effect.

Basic Technical Parameters

Specific recommended print settings (temperature, speed, flow, retraction) are available in the official Bambu Lab TPU 90A profile in Bambu Studio and may vary slightly according to the specific printer.

Material Properties

• High Elongation at Break – more than 650% in the XY plane.
• Excellent Impact Toughness – the material absorbs impacts very well.
• Fatigue Resistance – suitable for repeatedly stressed elements (movable joints, hinges, springs).
• Good Layer Adhesion – minimizes the risk of delamination when print settings are correct.

Printing Tips

• Print slower than standard PLA/PETG to prevent the filament from yielding in the extruder.
• Printing with TPU 90A is significantly more reliable with direct drive feeding.
• We recommend drying the material before long prints, especially in humid environments.
• For clean prints, limit excessive retractions and use the official Bambu TPU 90A profile.

Summary

Bambu Lab TPU 90A Crystal Blue is a reliable and easy-to-use flexible filament for users of Bambu Lab printers and other FDM devices with a suitable extruder design. It offers an excellent combination of flexibility, strength, and durability with an attractive translucent blue look, making it a great choice for functional parts and design projects requiring both flexibility and aesthetics.
