Compared to other metals, aluminum is lower density and allows for high-strength, lightweight components. However, due to its low tolerance to extreme heat and its tendency to crack during welding, aluminum is not typically used for additive manufacturing of rocket engine parts \u2013 until now. <\/p>\n<p>Meet NASA\u2019s latest development under the Reactive Additive Manufacturing for the Fourth Industrial Revolution, or RAMFIRE, project. Funded under NASA\u2019s Space Technology Mission Directorate (STMD), RAMFIRE focuses on advancing lightweight, additively manufactured aluminum rocket nozzles. The nozzles are designed with small internal channels that keep the nozzle cool enough to prevent melting. <\/p>\n<p>Video credit: NASA&#8217;s Marshall Space Flight Center<\/p>\n<p class=\"MsoNormal\" style=\"margin: 5px;\">&nbsp;<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>NASA recently built and tested a 3D printed rocket engine nozzle made of aluminum. <\/p>\n","protected":false},"author":2,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[12,463],"tags":[885,886],"class_list":["post-4165","post","type-post","status-publish","format-standard","hentry","category-spacecraft-design","category-videos","tag-ramfire","tag-stmd"],"_links":{"self":[{"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/posts\/4165","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/users\/2"}],"replies":[{"embeddable":true,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=4165"}],"version-history":[{"count":1,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/posts\/4165\/revisions"}],"predecessor-version":[{"id":4166,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=\/wp\/v2\/posts\/4165\/revisions\/4166"}],"wp:attachment":[{"href":"https:\/\/orbitalhub.com\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=4165"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=4165"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/orbitalhub.com\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=4165"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
