3Dresyn GrapNSEK1-MWCNT Bio Conductive Resin (Bio)

Product description

3Dresyn® GrapNSEK1-MWCNT Bio is a biocompatible, electrically and thermally conductive photopolymer based on multi-wall carbon nanotube (MWCNT) technology. It is designed as a ready-to-print conductive resin for additive manufacturing of functional components requiring enhanced electrical performance.

This formulation is based on a non-soluble (post-printing) matrix system, enabling stable and higher conductivity pathways compared to SWCNT systems, while maintaining excellent printability and resolution in SLA, DLP and LCD 3D printing technologies.
