3Dresyn GrapSEK1-SWCNT Water-Soluble Conductive Resin

3Dresyn® GrapSEK1-SWCNT is a single-wall carbon nanotube (SWCNT)-based electrically and thermally conductive photopolymer designed as a water-soluble sacrificial material for advanced additive manufacturing. It enables the fabrication of conductive structures that can be removed after processing, supporting complex multi-material and embedded electronics workflows.

This formulation combines conductive nanocomposite performance with controlled water solubility after printing, allowing the creation of temporary conductive pathways or sacrificial structures in functional devices.

Designed for use in SLA, DLP and LCD vat photopolymerization systems within research, development and industrial environments focused on conductive materials, embedded electronics and sacrificial manufacturing strategies.
