What is TPU 3D printing filament?

BigRep TPU 98A is a thermoplastic polyurethane—part of the thermoplastic elastomer family—with a Shore hardness of 98A, which is relatively firm. It offers temperature resistance up to 100 °C and a high level of chemical resistance making TPU 98A suitable for rugged industrial applications.

Mechanical Properties

TPU 98A has exceptional impact strength, registering no break on the Charpy notched impact test. It has a tear strength of 175 kN/m and an elongation at break of 450%.

Thermal Properties

BigRep's TPU 98A is temperature resistant up to 100°C with a Vicat softening temperature of 105°C and continuous use temperature of 50°C.

 Chemical Properties

Excellent chemical resistance is one of the key advantages of BigRep TPU 98A. It performs well against grease and oil making it great for use in factory environments.

Featured Application


Airless Tire & Nera eBike

Created by BigRep’s innovation design team, these airless tires were part of the fully 3D printed NERA eBike. The tires featured a honeycomb design that ensured internal stability while balancing rigidity and flexibility. The geometry was realized using BigRep TPU filament, which is firm and strong enough to maintain its shape during use but offers just enough flexibility to mimic the softness function of a traditional inflated tire.
