3Dresyn HF hard & flexible

Product description

3Dresyn HF is a flexible photopolymer formulation designed for applications requiring high flexibility combined with moderate hardness. The material enables the fabrication of parts capable of undergoing significant deformation without fracture, supporting foldable and resilient functional components.

This formulation provides a balance between elasticity and structural integrity, making it suitable for applications where flexibility, durability and repeated mechanical deformation are required.
