The Lithuanian resin manufacturer AmeraLabs has introduced FLX-300, a new elastomeric 3D printing resin developed for functional and durable applications. The material is designed to maintain its mechanical properties over time, bridging the gap between conventional flexible resins and technical elastomers. FLX-300 is intended for use in LCD and DLP printers and targets users who require parts with long-lasting elasticity and shape recovery.
While many flexible resins tend to harden and lose elasticity over weeks or months after printing, FLX-300 is said by the manufacturer to retain consistent surface hardness and flexibility. Internal tests showed that samples exhibited no measurable change in properties after three months of storage. This makes the material particularly suitable for applications involving repeated deformation or continuous mechanical stress.
“Most flexible resins are a compromise – they start soft but gradually harden over weeks or months,” said Andrius Darulis, co-founder of AmeraLabs. “We developed FLX-300 to maintain its properties over time. This opens up real engineering applications, not just temporary prototypes.”
Key characteristics include a low compression set, high elongation at break, and a silicone-like feel. Due to its low water absorption, dimensional stability is maintained even in humid environments, and according to AmeraLabs, the parts exhibit no shrinkage during post-curing.
FLX-300 is aimed at industrial users producing elastic components such as seals, damping elements, or grippers for soft robotics. In addition, the material offers potential for functional prototypes or customized parts with damping properties. AmeraLabs encourages developers and companies to test the new resin in specific projects to help drive the practical advancement of elastomeric printing materials.
