Made in Space, a recent acquisition of Redwire, has just for the first time successfully manufactured a ceramic part in their Ceramics Manufacturing Module on the ISS using additive manufacturing. The demonstration could stimulate demand in low Earth orbit from terrestrial markets which will be a key driver for space industrialization. Redwire claims that the parts, which included a turbine blisk (bladed disk) and other test pieces, demonstrate that the CMM can produce ceramic parts that exceed the quality of turbine components made on Earth.
According to Redwire’s press release: “CMM aims to demonstrate that ceramic manufacturing in microgravity could enable temperature-resistant, reinforced ceramic parts with better performance, including higher strength and lower residual stress. For high-performance applications such as turbines, nuclear plants, or internal combustion engines, even small strength improvements can yield years-to-decades of superior service life.”
