3Dresyn NSEK1 Bio Photopolymer Binder Resin (Bio)

3Dresyn® NSEK1 Bio is a biocompatible, non-conductive photopolymer binder designed for the custom formulation of conductive 2D and 3D printed materials. It is specifically engineered for applications in printed electronics, including antennas, RFID/NFC devices, OLEDs, OPVs, flexible PCBs and conductive tracks.

This material functions as a versatile matrix compatible with conductive additives, dispersants and anti-sedimentation systems, enabling the development of tailored electrically functional resins. It provides controlled solubility and swelling behavior, allowing tuning of processing and end-use performance.

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

Material performance depends on formulation with conductive additives, dispersion quality, printer type, exposure conditions and post-processing. Electrical, mechanical and chemical performance must be validated by the user for each specific application.

This material is supplied as a professional formulation component for research, development and manufacturing workflows. It is not marketed as a finished electronic or medical device. Final part performance and suitability must be validated by the user.

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