Extremely proud of this paper. Harsh did an excellent job synthesizing numerical results and theory to answer one of the most fundamental questions facing ISAM concepts — how do spacecraft capabilities determine the time needed to make a large structure on orbit? Harsh’s fabrication time diagrams are a powerful new tool for designing ISAM missions. They also have important potential applications in describing terrestrial manufacturing technologies, where there is often a trade-off between size, precision, and throughput. Congrats Harsh!
Excited to share my new paper on Fabrication Time Diagrams for In-Space Manufacturing of Large Reticulated Structures! 🛰 🤖 In this work we quantify the fabrication time of large support structures on orbit and develop diagrams that depict the dominant constraints on fabrication time for a range of dimensions. Our results show design tradeoffs between the number of spacecraft, feedstock material, and attitude control authority to reduce fabrication time, highlighting how the design of the spacecraft cannot be considered independently of the fabrication process. For instance, we estimate that 5 spacecraft can fabricate a 200-m diameter gridshell from carbon fiber tubes in 5 days.
