3D-Printable Graphene Inks
A New Formulation Development Paves The Way for Sustainable Innovation
Georgia Wray Norsten — August 8, 2025
'3D-Printable Graphene Ink' developed by researchers at the University of Waterloo promises to transform industries from automotive to healthcare, thanks to its eco-friendly, solvent-free formulation. The breakthrough material enables additive-free 3D printing of graphene -- a substance known for its exceptional strength, conductivity, and thermal performance -- previously limited by its powdered form.
Led by Dr. Milad Kamkar from Waterloo’s Department of Chemical Engineering, the team engineered graphene nanosheets dispersible in water without chemical solvents or additives. The innovation, created in partnership with researchers from Calgary, UBC, and Finland’s Aalto University, uses a scalable electrochemical process and intercalation technique for mass production.
With applications in embedded IoT, printed electronics, wearable sensors, and environmental remediation, this water-based ink supports Canada's push toward circular manufacturing. As a sustainable alternative to silver-based or polymer inks, it could lower costs, boost efficiency, and reduce environmental impact across sectors.
