3Dresyn PP FA40 Flexible A40

3Dresyn PP FA40 is a highly flexible, elastomeric photopolymer formulation designed to provide very low modulus, extreme elasticity and excellent foldability while maintaining structural integrity. The material enables the fabrication of durable components capable of undergoing very large deformation and repeated compression cycles without failure.

This formulation is engineered to deliver an ultra-soft rubber-like mechanical profile (Shore A scale), making it particularly suitable for applications requiring maximum compliance, full surface adaptation and energy absorption.

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within professional and industrial environments for ultra-soft, elastic and highly deformable components.

Particularly suitable for ultra-soft elastomeric printing plates where extreme compression, full surface conformity and repeated deformation cycles are required.
