3Dresyn GrapSEK1-MWCNT Bio Water-Soluble Conductive Resin (Bio)

3Dresyn® GrapSEK1-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 with controlled water solubility after printing, enabling both functional conductive parts and sacrificial conductive structures.

This formulation combines high conductivity nanocomposite performance with water-soluble behavior, supporting advanced additive manufacturing strategies including removable conductive pathways and embedded electronics.

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 manufacturing workflows.
