In parallel with our efforts, Vazquez-Martel and co-workers demonstrated the use of microalgae as sustainable sources for the development of biocompatible material for 3D printing . With their research, they produced microstructures with additive-free ink for two-proton 3D laser printing using chlorophyll derivates already present in the microalgae extract. They also assessed the cytocompatibility of the obtained material through cell viability assays. However, the findings for the microstructures printed can be difficult to apply on a larger scale and require some modification. In our work, great attention is given to the optimization of the synthesis and the formulation of the resin to obtain printability and mechanical properties that are competitive with commercial resins.
