3Dresyn GrapNSEK1-MWCNT Bio Conductive Resin (Bio)

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.

Designed for use in vat photopolymerization systems (SLA, DLP and LCD) within research, development and industrial environments focused on conductive materials, functional devices and advanced additive manufacturing.
