3Dresyn HP1 Clear High Permittivity optically transparent resin

Product description

3Dresyn® HP1 Clear is a high-permittivity optically transparent photopolymer designed for advanced dielectric and electronic applications. The material combines elevated dielectric performance with optical clarity, enabling the fabrication of functional components requiring both electrical performance and visual transparency.

This formulation is based on a highly polar, ultra-pure resin system engineered to achieve enhanced dielectric properties while maintaining excellent printability and surface resolution in SLA, DLP and LCD workflows.
