3D Bioplotter Research Papers

In this study, we successfully fabricated a three-dimensional Co3O4@SiO2 3D Monolith catalyst. This process allowed for the effective and straightforward anchoring of Co3O4 nanoparticles onto SiO2 3D Monoliths. The active Co3O4 phase was primarily identified through XRD and XPS analyses, complemented by Co3O4 loading measurements (1.7 %). This innovative catalyst displayed remarkable proficiency in selectively converting propane to carbon dioxide. Additionally, it was demonstrated that the catalytic activity remained unimpaired even upon the catalyst’s reuse in 5 successive reaction cycles. This performance was observed across various heating ramps, showcasing the catalyst’s stability over time.

With the increasing need for architectural sustainability, biodesign offers a new approach to incorporating living organisms in building materials. Bacteria hold a range of biological activities that impact their environment, and which could enable the solidification of inorganic materials; this has already been seen with microbially-induced carbonate precipitation that strengthens bonds between sand particles. This paper describes the novel development of an additive co-fabrication manufacturing process, demonstrating an interdisciplinary approach of architecture and microbiology. Specifically, the activity of a biological deposition (i.e., cyanobacterial calcium carbonate precipitation) and its integration with that of a robotic deposition (i.e., a sand-based biomixture) within…
