TPU 95A
TPU 95A — Flexible.
Impact-Proof.
Thermoplastic Polyurethane with 95A Shore hardness is the go-to material for flexible, rubber-like parts. 123 kJ/m² impact strength, >650% elongation, and cold-temperature resilience make it ideal for grips, seals, gaskets, and wearable parts.

About TPU 95A
TPU 95A (Thermoplastic Polyurethane, Shore 95A hardness) is a semi-rigid, rubber-like material that deforms under load and returns to its original shape. With a Young's modulus of just 9.8 MPa (vs 2200 MPa for ABS), it is fundamentally different from all rigid FDM materials — behaving more like an injection-moulded rubber than a thermoplastic.
We use Bambu TPU 95A HF — a high-flow formulation that prints at up to 200 mm/s, resolving the slow-print limitation of traditional TPU. It maintains exceptional interlayer adhesion and cold-temperature flexibility, delivering rubber-like performance on a fast-turnaround production timeline.
With a 123 kJ/m² impact strength and >650% elongation before breaking, TPU 95A absorbs shock loads that would shatter any rigid material. It is chemically resistant to oils and greases and can be printed in 4 colours to suit a wide range of product applications.
