3Dresyn GrapSEK1-GNP, graphene nanoplatelets based electrically conductive water soluble 3D resin

Product description

3Dresyn® GrapSEK1-GNP is a graphene nanoplatelet (GNP)-based electrically and thermally conductive photopolymer designed as a water-soluble sacrificial material for additive manufacturing. It enables the fabrication of conductive structures that can be removed after processing, supporting applications such as electroforming and advanced multi-material manufacturing.

This system combines graphene-based conductive performance with controlled water solubility after printing, allowing the creation of temporary conductive geometries and sacrificial structures.

Chemical and safety characteristics

• Nanocomposite system containing graphene nanoplatelets
• Organo-tin free formulation

Storage and handling note

Once mixed, the product has a limited working time and reduced shelf life, especially at temperatures above 40–50 °C. Storage at low temperature (refrigeration) can extend usability. It is strongly recommended to print shortly after mixing to avoid premature gelation.

Testing & processing disclaimer

Electrical performance depends on formulation, dispersion quality, geometry, printing parameters and post-processing conditions. Conductivity values are indicative and must be validated by the user for each specific application.
