Bambu Lab TPU 90A White 1 kg

Bambu Lab TPU 90A White 1 kg

Flexible filament Bambu Lab TPU 90A White is designed for users who need parts with higher flexibility, but also good dimensional stability and strength. With a hardness of Shore 90A, it falls in the medium range of TPU materials – it is softer than common rigid plastics (PLA, PETG), but stiffer and more manageable than extremely soft TPU (e.g., 85A).

Main advantages and use

• Shore hardness 90A – ideal compromise between flexibility and structural strength
• Excellent shock absorption – suitable for parts that must absorb impacts and vibrations
• High abrasion resistance – the filament is designed for long-term mechanical stress
• Combination with PLA and PETG – Bambu TPU 90A can be combined with PLA/PETG in dual printing (on compatible dual-nozzle Bambu Lab H2C/H2D printers)
• Reliable diameter quality – 1.75 mm diameter with very precise tolerance for consistent extrusion
• White color – universal technical appearance, suitable also for final design parts
• Reusable, temperature-resistant spool – more environmentally friendly and resistant to higher temperatures in enclosed printers

Typical applications:

• grips, handles, ergonomic covers
• bumpers, stops, damping elements
• soles and shoe parts, insoles
• RC tires and rubber parts of models
• seals, grommets, flexible clips
• protective covers, cases, impact-resistant packaging

Printing recommendations

Bambu Lab TPU 90A is a soft material, so it is important to follow several principles:

• Drying before printing – TPU is highly hygroscopic, so it is necessary to dry the filament before printing (e.g., 55–60 °C for several hours) and ideally store it in a dry box.
• Lower printing speed – for consistent extrusion of flexible filaments, lower speeds compared to PLA/PETG are recommended.
• AMS/AMS Lite compatibility – Bambu TPU 90A is not officially compatible with AMS/AMS Lite feeders, direct feeding into the printer is recommended.
• Bed adhesion – use a suitable Bambu Lab print profile for TPU 90A and the recommended bed type (e.g., textured PEI), or an adhesive agent for better adhesion of the first layers.

Technical specifications

Note: Specific nozzle and bed temperatures, speeds, and other parameters can be found in the official Bambu Lab TPU 90A profile in the Bambu Studio slicer for your printer.

Who is Bambu Lab TPU 90A suitable for

Bambu Lab TPU 90A is ideal for users who:

• want to print functional flexible parts with higher durability,
• need better manageability and stability of the material than with extremely soft TPUs,
• use the Bambu Lab ecosystem and want a seamless profile directly in Bambu Studio,
• are looking for a reliable premium TPU filament for technical and hobby projects.

Thanks to the combination of ease of use, excellent mechanical resistance, and support in the Bambu Lab ecosystem, TPU 90A White represents a great choice for every workshop working with flexible parts.

Key features:

• Premium Bambu Lab TPU filament with Shore 90A hardness for balanced flexibility and strength
• High abrasion resistance and long life even under repeated stress and bending
• Excellent shock absorption – ideal for grips, bumpers, soles, and protective parts
• Possibility of combination with PLA and PETG in dual printing on compatible Bambu Lab printers
• Reliable 1.75 mm diameter precision for stable extrusion and high-quality print surfaces
• White color for universal technical and design use
• Supplied on a reusable, temperature-resistant spool
