Flexible 3D printing filament: Markforged develops rubber-like material

Finally, a simple and cost-effective way to print functional, flexible parts

When you think of things like gaskets, shock absorbers, hoses and drive belts, TPU plastic is one of the few materials used to make these parts. Markforged is launching Smooth TPU 95A, a rubber-like material used to make flexible, shock-absorbing parts. 3D printing filament enables the production of custom designs on demand, exactly where they are needed.

Fields of application

The production of flexible, rubber-like parts, which are slow and expensive to obtain in small quantities, is now simplified and cost-effective.


• Seals and closures
• Shock absorbers
• Protective covers
• Belts, tapes and drive belts
• Gentle workpiece holder and handles
• Wheels and treads

Smooth TPU 95A - Thermoplastic polyurethane black and white

Smooth TPU 95A (thermoplastic polyurethane) is an elastomer material and is ideal for functional parts that require stretchability and flexibility. This can be used to print drive belts, bumpers, protective covers, seals and other extremely reliable parts with a smooth surface.
