The absorber is 3D-printed from nickel-titanium shape memory alloy, and is intended for future lunar and planetary landers.<\/p>\n\n\n\n<h4 class=\"wp-block-heading\">From material to full-scale design<\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">CSEM led the project from concept to demonstration. Its team selected and narrowed down the lattice geometries, developed the manufacturing parameters for fine nickel-titanium lattices, produced by laser powder bed fusion, a process that requires careful control, and ran quasi-static, high-speed impact and reusability tests. Almatech used these test data to analyze the landing-leg system and translate the material&#8217;s behavior at laboratory scale into a full-scale shock absorber design.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Vaclav Pejchal, Material &amp; Technology Expert at CSEM, says that RESHAPE demonstrates that shape memory alloy lattice structures can deliver predictable and reusable impact absorption, and that combining these alloys with additive manufacturing lets the team rethink components that have remained largely unchanged for decades. Dr. Fabrice Rottmeier, Chief Technology Officer of Almatech, describes the collaboration as very positive, pairing CSEM&#8217;s technological expertise with Almatech&#8217;s space engineering to turn ideas into solutions for space missions.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Watch our <a href=\"https:\/\/www.youtube.com\/watch?v=q4OSD2cBcoU\">Getting Serious episode<\/a> with CSEM CEO Dr. Alexandre Pauchard, who examines the foundations of Switzerland&#8217;s innovation leadership and the risks linked to scale-up financing.<\/p>\n\n\n\n<figure class=\"wp-block-embed aligncenter is-type-video is-provider-youtube wp-block-embed-youtube wp-embed-aspect-16-9 wp-has-aspect-ratio\"><div class=\"wp-block-embed__wrapper\">\n<iframe loading=\"lazy\" title=\"Switzerland Is #1 in Innovation, But for How Long?
