When the excess materials aren\u2019t used, they contribute to unnecessary waste, financial burdens and launch and process-related carbon dioxide emissions on Earth.<\/p>\n\n\n\n<p>\u201cLess than five percent of spare parts carried on space missions are actually used,\u201d says Zhu. \u201cIf equipment was manufactured where it is needed, we could make space exploration more sustainable.\"<\/p>\n\n\n\n<p>Zhu\u2019s work will involve collaboration with fellow Lassonde School of Engineering mechanical engineering professors <strong>Alidad Amirfazli<\/strong>, <strong>Cuiying Jian<\/strong> and <strong>Aleksander Czekanski<\/strong>, as well as taking full advantage of the diverse fields of mechanical engineering research at York, including space instrumentation and robotics, molecular dynamics, metals and alloy materials and fluid mechanics.<\/p>\n\n\n\n<p>\u201cSpace has different conditions than Earth that will affect 3D printing, mainly zero-gravity and vacuum, so there will be a lot of exploratory work,\u201d says Zhu. \u201cWhen we use 3D printing on Earth, the gravity helps create strong bonds, but we don\u2019t know what will happen in conditions without gravity. It is possible that the vacuum might cause molten metals to vaporize and disappear right in front of us.<\/p>\n\n\n\n<p>\u201cWe want this to work but at this stage, we don\u2019t know what will happen. We are actually the first to do this kind of research with metals,\" he adds. <\/p>\n\n\n\n<p>Using equipment obtained with substantial funding from the Canadian Foundation for Innovation (CFI) in 2019, this project will simulate space-like conditions to determine the feasibility of, and potential practices for, metal 3D printing in space. 3D printing will be performed in a large vacuum chamber, while modelling zero-gravity by printing in a horizontal orientation rather than vertical \u2013 this helps avoid the direct pressure from gravity that supports the creation of strong bonds.<\/p>\n\n\n\n<p>The newly funded research will also explore the use of 4D printing, a new method of 3D printing that incorporates the dimension of time and may be useful in the development of deployable spacecraft components, like solar panels. Using shape memory alloys (SMA), 4D printed materials can remember and revert to their original shape after being deformed by certain stimuli, presenting a potential application for spacecrafts that spend long periods of time in space and are vulnerable to damage from debris.<\/p>\n\n\n\n<p>Contributing to sustainable spacefaring effort, this exploratory project will take the first steps towards using space as an on-demand manufacturing site for space equipment. This project will also explore new and exciting ideas that can change and improve the design of space equipment, including the recycling of materials from debris to repair and manufacture materials for space activites.<\/p>\n\n\n\n<p>\u201cWe have plans and ideas for applications, but this research is very new,\u201d says Zhu. \u201cI\u2019m excited to learn as we go and discover the unknown. If this is successful, it will change the future of space exploration.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>George Zhu received $250,000 from the New Frontiers in Research Fund
