High-Durability Printable Materials

EPFL Develops Tough 3D Printable Elastomers for Soft Robotics

High-durability printable materials are expanding the capabilities of additive manufacturing by overcoming the traditional trade-off between toughness and fatigue resistance. Researchers at EPFL developed double network granular elastomers that can be 3D printed while withstanding repeated stretching, impacts and mechanical stress without compromising durability. Their unique dual-network structure redistributes strain throughout the material, slowing crack growth and extending component lifespan. This combination makes the material well suited for demanding applications such as soft robotics, wearable electronics and biomedical devices that require flexibility and long-term reliability.

For businesses, durable printable materials can reduce maintenance requirements, improve product performance and extend the service life of components exposed to continuous movement. The ability to manufacture stronger, longer-lasting parts with commercial 3D printers also supports faster product development and greater design flexibility. As additive manufacturing continues to evolve, advanced elastomers are positioned to unlock new opportunities for high-performance, customized products across multiple industries.
