For example, the material used in the article is Nd: YAG, normally used as a solid-state laser source in the infrared range.\u201d<\/p>\n<p>\u201cThe ability to fabricate complex and miniature devices that have performance similar to silicon ones,\u201d says Shlomo Magdassi, researcher at the Hebrew University of Jerusalem, \u201cby a quick and simple 3D printing process, brings new horizons to the field of additive manufacturing and rapid manufacturing.\u201d<\/p>\n<p>&nbsp;<\/p>\n<p>Image \u2013 <em>Courtesy of: Pixabay\/CC0 Public Domain<\/em><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>For more information:<\/p>\n<p>&nbsp;<\/p>\n<p>Hebrew University of Jerusalem<\/p>\n<p><a href=\"https:\/\/en.huji.ac.il\/en\" target=\"_blank\" rel=\"noopener\">https:\/\/en.huji.ac.il\/en<\/a><\/p>\n<p>&nbsp;<\/p>\n<p>Politecnico di Torino<\/p>\n<p><a href=\"https:\/\/www.polito.it\/\" target=\"_blank\" rel=\"noopener\">https:\/\/www.polito.it\/<\/a><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Collaborating researchers from the Politecnico di Torino, Italy, and the Hebrew University of Jerusalem, Israel, 3D printed mechanical nanoresonators with properties such as quality factor, published stability, mass sensitivity, and strength comparable to those of silicon resonators.<\/p>\n","protected":false},"author":63103,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[448,434,439,435,436,1],"tags":[],"class_list":["post-6039","post","type-post","status-publish","format-standard","hentry","category-aerospace-and-defense","category-electronics","category-materials-processing-and-treatment","category-news","category-news-articles","category-uncategorized"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.9 -
