EPFL Develops Durable Elastomers for 3D Printing

Scientists at the Swiss Federal Institute of Technology Lausanne (EPFL) have successfully developed a new class of elastomer materials designed for 3D printing. These materials exhibit significantly improved resistance to various forms of degradation, a common challenge with existing flexible 3D printable polymers.

The research focused on enhancing the durability of elastomers, which are known for their flexibility and elasticity. Traditional flexible 3D printing materials often lose their mechanical properties when exposed to heat, UV radiation, or prolonged mechanical stress. The EPFL team's innovation lies in the formulation of these new elastomers, which are engineered to maintain their integrity and performance under demanding conditions.

This breakthrough has the potential to expand the range of applications for 3D printed flexible components. Previously, the limited lifespan and susceptibility to environmental factors restricted the use of 3D printed elastomers to prototyping or low-stress applications. The development of these more robust materials opens doors for their use in functional parts that require long-term reliability.

While specific applications are still being explored, the enhanced resistance suggests suitability for areas such as robotics, wearable technology, and even components in harsh environments where flexibility and durability are paramount. The EPFL's work represents a significant step forward in additive manufacturing, enabling the creation of more resilient and functional flexible parts.
