Herein, we present for the first me the use of microalgae as "biofactories" to generate materials that can be further used in high resolu on 3D prin ng exhibi ng good prin ng performance and biocompa bility (Figure ). In par cular, two microalgae strains with high content in lipids, and more specifically, triglycerides, were selected and cul vated. The extracted triglycerides were further func onalized and used as prin ng materials. Interes ngly, we also exploited the extracted chlorophylls from the microalgae as photoac ve system to induce polymeriza on without the necessity of adding a photoini a ng system. To the best of our knowledge, the use of chlorophylls for light-based 3D prin ng is en rely unprecedented. In the following step, we showcased the feasibility of manufacturing intricate 3D structures via two-photon laser 3D prin ng. The 3D printed structures were characterized in depth and their biocompa bility was studied via cell viability assays.
