3Dresyn IJ HDT2 High Heat Deflection Temperature

Product description

3Dresyn IJ HDT2 High Heat Deflection Temperature is an ultra rigid high-temperature photopolymer formulation designed for demanding inkjet 3D printing applications requiring very high hardness, very high rigidity and exceptional thermal resistance. The material is engineered to deliver rigid structural performance together with very high resolution, very low shrinkage and reliable inkjet printability.

This formulation provides a combination of high rigidity, very low elongation and very high Shore hardness, enabling the fabrication of ultra rigid parts with excellent thermal resistance and controlled dimensional stability for demanding engineering and high-temperature applications.
