TPU 85A & 90A: The Best Choice for Impact Absorption

Engineered for durability and flexibility, Bambu TPU 85A and 90A are the perfect filaments for shock absorption and soft support, making them ideal for applications like padding, medical braces, and protective gear.

Bambu TPU 85A – The softest in Bambu's lineup, offering exceptional flexibility and resilience. Perfect for impact-absorbing parts such as protective cases, squishy fidget toys, and soft cushioning elements.

Bambu TPU 90A – With a higher hardness, it provides greater structural integrity, making it ideal for shoe soles, RC tires, and functional components that require both flexibility and strength.

Both filaments deliver outstanding wear resistance, ensuring long-lasting performance even after repeated bending—making them the go-to choice for high-demand applications.

*TPU 85A and 90A require highly precise printing conditions. Before printing, please carefully read the Printing Guide for TPU 85A & TPU 90A on the wiki to ensure the best results.

Drying conditions

Blast drying oven: 70 ℃, 8 h
X1 printer's heatbed: 90 ℃, 16 h

To avoid spool deformation that may prevent it from fitting into the dry box, please use a large dry box. For more details on filament drying conditions, please carefully read the filament drying section on the wiki.

Printing

Increasing the max volumetric speed is not recommended. Please keep the default speed during printing.
All the parameters of Bambu TPU 85A & 90A are already pre-set. Please turn off Flow Dynamics Calibration to match the fine-tuned setting.

Filament Unload

For detailed filament unloading instructions, please refer to wiki.
Do not press Unload when switching filaments, as this may cause uncut TPU residue to get stuck in the extruder.
Please heat the nozzle to 250°C, then control the extruder to retract and manually pull out the filament.
