3Dresyn PEDOTEK1 Bio, electrically conductive biocompatible 3D resin based on PEDOT:PSS

Product description

3Dresyn® PEDOTEK1 Bio is a biocompatible electrically conductive photopolymer based on PEDOT:PSS technology, designed for the additive manufacturing of conductive components for advanced electronics applications. It is supplied as a ready-to-print formulation, enabling direct fabrication of conductive structures without the need for additional conductive fillers.

This formulation combines intrinsic conductivity with improved safety and biocompatibility, together with controlled processing behavior for SLA, DLP and LCD 3D printing workflows.

Important processing note

Conductive photopolymers require precise control of printing parameters, material handling and post-processing. Optimal performance is achieved using open-mode systems and experienced users.

Storage and supply note

This product has a shelf life of approximately 6 months when stored below 25 °C. Storage at 4 °C (refrigerated, sealed) can extend shelf life. Products are manufactured to order to maximize performance and stability. Typical delivery time is approximately 2 weeks after ordering.

Testing & processing disclaimer

Electrical, mechanical and dimensional performance depends on printing parameters, water evaporation, geometry and post-processing. All properties must be validated by the user for each specific application.

Disclaimer

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