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

3Dresyn® PEDOTEK1 is an electrically conductive photopolymer based on PEDOT:PSS technology, designed for the additive manufacturing of conductive components for 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 material combines intrinsic conductivity with controlled processing behavior, allowing the fabrication of functional electronic components using SLA, DLP and LCD 3D printing technologies.

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

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

• Compatible with SLA, DLP and LCD 3D printing systems
• Requires open-mode printers and experienced users for optimal results
• Water evaporation (before or after printing) required to achieve final properties
• Up to 40% dimensional shrinkage must be considered in design
• PEDOT:PSS dispersion may require re-mixing to avoid agglomeration
• Fine tuning of exposure parameters recommended using dedicated fine tuning systems
• Specific IFU recommended for each printer and application

This product has a shelf life of approximately 6 months when stored below 25 °C. Storage at 5–10 °C in a sealed container can extend shelf life. Do not freeze or store below 4 °C. Avoid temperatures above 50 °C. PEDOT:PSS dispersions may undergo sedimentation, phase separation or agglomeration during storage or transport, especially after temperature fluctuations. Before use, the product must be fully homogenized to restore the suspension. If agglomeration is observed, re-homogenization with a high-speed homogenizer may be required. Typical delivery time is approximately 2 weeks after ordering.

• Contains PEDOT:PSS conductive system
• Non-biocompatible in liquid state (hazard classifications H302, H373)
• Improved biocompatibility after full curing and cleaning (application-dependent validation required)
• Organo-tin free formulation

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.

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.

For conductive 3D resin selection, compare the PEDOT:PSS route with the wider electrically conductive resin family and related conductive / ESD additive routes.
