3Dresyn IJ HF hard & flexible

Product description

3Dresyn IJ HF hard & flexible is a hard and flexible photopolymer formulation designed for professional inkjet 3D printing applications. The material is engineered to combine moderate hardness with high foldability and practical flexibility for general-purpose and functional applications.

This formulation provides a balance between structural definition and flexible response, enabling the fabrication of parts with good durability, very high resolution and reliable inkjet printability.
