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.
Seamless Multi-Material Printing: Strong in Structure, Soft to the Touch*
Bambu TPU 90A seamlessly prints with all Bambu PLA and PETG series, allowing you to create prints that combine flexible and rigid filaments through beam interlocking in Bambu Studio. From seat cushions and helmet padding to tool handles and beyond—design freely to achieve the perfect balance of stiffness and softness. Bambu Filaments empower you to expand the functionality of your prints.
* This function is exclusive to Bambu TPU 90A and compatible dual-nozzle printers like Bambu Lab H2D.
