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

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.

Designed for use in SLA, DLP and LCD vat photopolymerization systems within research, development and industrial environments focused on conductive materials, electroforming and advanced manufacturing workflows.

• 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 support material for additive manufacturing workflows. It is not intended as a final part material. Final part performance depends on the primary build material and processing conditions.

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