Helmholtz-Zentrum Hereon has developed a water-based 3D printing ink composed of 70% upcycled lignin from industrial waste.

Originally reported by Bioengineer

Helmholtz-Zentrum Hereon has developed a water-based 3D printing ink composed of 70% upcycled lignin from industrial waste. This material enables Direct Ink Writing at room temperature, eliminating the need for fossil-based polymers or high-heat curing. The core breakthrough is its 100% recyclability: printed parts can be rehydrated back into ink form and reused multiple times without structural loss. This innovation drives a systemic shift toward a closed-loop, bio-based manufacturing ecosystem. ♻️🌱 #3DPrinting #CircularEconomy #MaterialScience #Sustainability
