3Dresyn GrapNSEK1-GNP Bio, biocompatible graphene nanoplatelets based electrically conductive non soluble 3D resin

3Dresyn® GrapNSEK1-GNP Bio is a biocompatible, electrically and thermally conductive photopolymer based on graphene nanoplatelet (GNP) technology. It is designed for the additive manufacturing of conductive components and functional materials for electronics applications.

This system combines a graphene-based conductive additive with a non-soluble photopolymer matrix, enabling the fabrication of stable conductive structures while maintaining high resolution and printability in SLA, DLP and LCD 3D printing systems.

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

• It is strongly recommended to print shortly after mixing to avoid premature gelation

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

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.

This material is supplied as a professional manufacturing material and is not marketed as a finished medical device. Final part performance and suitability must be validated by the user according to the intended application.

This technical datasheet should be used together with the relevant processing, calibration, safety and workflow documentation available in the 3Dresyns® Resources section.
