Towards additively manufacturing excavating tools for future robotic space exploration
Engineering Reports, Volume 2, Issue 8, August 2020., 2020 Multiple metal alloys, additively manufactured through laser powder bed fusion, were tested as potential excavating tools for future robotic spacecraft landing on icy planetary bodies. Mechanical specific energy as a function of blade hardness was measured for each excavating tool as it trenched through soft and hard salt, where the salt is a regolith ...
