Titanium dioxide foams created using 3D - printing have been subjected to testing in extreme environmental conditions characteristic of Low-Earth Orbit (LEO).

This research article focuses on integrating studies in materials science, the physics of liquid foams, and 3D printing technologies to enhance robotic fabrication of titanium dioxide (TiO2) foams and analyze their degradation behavior under Low Earth Orbit (LEO) space conditions. These TiO2 foam structures hold significant promise for a variety of space applications, including efficient solar cells, advanced batteries, and radiation shielding. The experimental investigations are proposed to utilize the MISSE–FF platform aboard the ISS, where Earthprinted foam samples will be exposed to LEO environmental conditions. Upon their return, a comprehensive range of characterization techniques will be employed to examine potential degradation mechanisms. This evaluation will provide critical early insights into the suitability of TiO2 foam materials for targeted space applications, facilitating further exploration of their manufacturing under microgravity conditions. By the conclusion of this study, a broader understanding of how TiO2 foams degrade in LEO is anticipated. This includes identifying erosion mechanisms impacting the foams' organic components due to high atomic oxygen flux. Additionally, the research aims to evaluate how carbon-based materials such as graphene and carbon nanotubes (CNTs) might contribute to reinforcing these printed structures, enhancing their performance and durability for space missions.
