| Abstract Scope |
Among the different electrohydrodynamic processes, melt electrowriting (MEW), has achieved a great development for biomedical materials design, because of its ability to generate macro-structures with complex micro-features.
Aqueous solutions electrowriting conserve the potential for high-resolution microscale printing but also bring new opportunities for materials processing. To boost its visibility, current research proposes a cryogenic stage that allows the freezing of EHD jets, to facilitate the 3D growth of structures. Using silk fibroin highly viscous solutions, microfibers of around 30 µm have been successfully stacked one-each other to achieve complex macrostructures. The obtained scaffolds show excellent biological response and capacities for cell guidance. In addition, porous fibers present micro-channels that invite us to explore their potential in different fields.
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. |
