3Dresyn GrapSEK1-MWCNT Bio, biocompatible multi wall carbon nanotubes based electrically conductive water soluble 3D resin

Product description

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.
