TPU Filaments for Flexible 3D Printing

TPU (thermoplastic polyurethane) is a flexible 3D printing material that combines rubber-like elasticity with good mechanical durability. Unlike rigid filaments such as PLA or PETG, TPU allows printed parts to bend, compress and deform while largely returning to their original shape when the load is removed.

Its excellent abrasion resistance, impact absorption and resistance to repeated flexing make TPU suitable for both everyday accessories and demanding functional components.

What Can You Print with TPU?

TPU is widely used for applications requiring flexibility, cushioning or impact resistance:

• Seals and flexible connectors - components that need to deform and maintain a close fit.
• Protective cases and bumpers - protecting electronics, tools and equipment from impacts.
• Wheels and tyres - components for robotics, models and mechanical devices.
• Vibration dampers - absorbing shocks and reducing vibrations.
• Flexible mounts - clips, holders and connectors that need to bend without breaking.

Choosing the Right TPU Hardness

TPU filaments are available in different hardness levels, typically measured on the Shore A scale.

TPU 95A is one of the most popular options, offering a practical balance between flexibility, durability and ease of printing.

Softer TPU formulations provide greater elasticity but are generally more challenging to print. Harder grades are better suited to parts requiring improved dimensional stability.

Tips for Printing TPU

A 3D printer equipped with a Direct Drive extruder is generally recommended for flexible filaments. TPU is typically printed at lower speeds than PLA or PETG to ensure consistent material feeding.

Proper storage is also important, as TPU absorbs moisture from the air, which can affect extrusion consistency and surface quality.
