| Abstract Scope |
Aqueous solutions electrowriting shows great potential for high-resolution microscale printing while bringing new opportunities for new materials processing. To boost its visibility, current research brings the combination of new technology, sustainable inks, and composites development to fulfill advanced applications. A cryogenic stage allows the freezing of EHD jets, to facilitate the 3D growth of structures. Highly viscous silk fibroin aqueous solutions, bring microfibers of around 30 µm which can be successfully stacked on each other to achieve complex micro-structures. The further combination with magnetic nanoparticles allows the scaffolds to respond to magnetic fields.
The obtained structures, show excellent biological response and capacities for cell guidance, but also the potential for soft robotics and actuators. With this approach, the suitability of a new type of 3D-printed material is achieved, as the time that the complexity and requirements of the new technology are tested. |
