Graphene 3D printing using liquid developed by Korean scientists

Researchers from the Korea Electrotechnology Research Institue (KERI) managed to create an innovative process of 3D printing graphene nanostructures.

The scientists announced the development of a nanoscale 3D printing approach that exploits a liquid meniscus of ink to create 3D reduced graphene oxide (rGO) nanowires, different than typical methods that use filaments or powders as printing materials.

Despite the fact that methods of 3D printing graphene/thermoplastic composites (like selective laser sintering and fused deposition modelling) exist, most of them have an adverse effect on the material's properties. The Korean team declares their method of printing pure graphene nanostructures mush less harmful to the material.
