Bambu Lab TPU 85A in Black is an ultra-soft flexible filament with a Shore A hardness of 85, designed for printing highly elastic parts that need to bend, stretch or absorb impact repeatedly without cracking. It is fully compatible with Bambu Lab printers and engineered to feed reliably at the speeds these machines are known for.

Black TPU 85A is the most versatile colour in the lineup - neutral enough for professional use cases such as industrial gaskets, cable strain reliefs, anti-vibration mounts and protective bumpers, while remaining visually clean in consumer-facing wearable accessories and ergonomic grips. The high shore softness makes it ideal wherever comfort or compliance under load is a priority.
