De wetenschappers hebben een nieuwe veelbelovende technologie gepresenteerd voor het printen van micro-objecten van metaal met zeer hoge resolutie \u2013 tot 250 nm. Tegenwoordig wordt 3D-printing van micro-objecten van metaal uitgevoerd met behulp van speciale inkten. Dit zijn nanodeeltjes van metaal die in vloeistof worden geplaatst als een suspensie. De resolutie van dergelijke printers bedraagt micrometers en de print eindigt met een verplichte annealing om het model te fixeren. In deze laatste fase zijn er veel tekortkomingen, waaronder lage pori\u00ebnvorming en vervuiling met organische stoffen (oplosmiddelen). Wat hebben de Zwitsers te bieden?<\/p>\n<p><img decoding=\"async\" alt=\"3D-printing van metalen is ontwikkeld met een resolutie van 250 nm\" src=\"\/wp-content\/uploads\/2019\/05\/e04d65eef14c2918b2ec4caa337203c5.jpg\" style=\"display:block;margin: 0 auto;\" \/><br \/>\n<\/center><\/p>\n<p>Wetenschappers uit Z\u00fcrich hebben de metalen suspensie vervangen door directe printen met metalen. Meer precies, met metaalionen. Er is een ontwerp van een printkop voorgesteld met twee zogenaamde verbruikbare anodes. Waarom twee? Omdat dat beter is! Het is mogelijk om een metalen micro-object om de beurt met \u00e9\u00e9n of de andere metaal, of zelfs met beide tegelijk te printen, zoals het cre\u00ebren van een legering met de gewenste verhouding van het ene en het andere materiaal. Het principe van de voorgestelde 3D-printing is dat onder hoge spanning, geleid naar de anode, de metaalionen zich losmaken en naar het substraat vliegen, waar ze zich vestigen en in het oorspronkelijke metaal veranderen. Om dit te laten werken, is het substraat bedekt met een laag oplosmiddel, waarin oxidatie-reductie chemische reacties plaatsvinden. Hierdoor gebeurt de printing direct met schoon metaal en is er geen verdere annealing nodig.<\/p>\n<p><center><div class=\"youtube-placeholder\" data-id=\"GVTclHY_6UM\" onclick=\"loadVideo(this)\">\r\n        <img decoding=\"async\" src=\"https:\/\/img.youtube.com\/vi\/GVTclHY_6UM\/hqdefault.jpg\" alt=\"Video afspelen\" loading=\"lazy\" width=\"480\" height=\"360\" style=\"width:100%;height:auto;\">\r\n        <div class=\"play-button\"><\/div>\r\n    <\/div><\/center><\/p>\n<p>Er zijn veel toepassingen voor dergelijke technologie\u00ebn. Maar het eerste dat in je opkomt, zijn micro-elektronica en de creatie van metamaterialen met ongebruikelijke eigenschappen. Printen met een dergelijke precisie helpt om ultradunne verbindingen te maken en zelfs organische materialen in de elektronica te gebruiken. Wat metamaterialen betreft, kan de combinatie van metalen leiden tot de ontwikkeling van materialen met interessante mechanische eigenschappen, zoals zowel flexibel als sterk.<\/p>\n<p><center><\/p>\n<p><\/center><\/p>\n<p>\t\t\t\t<center><br \/>\n\t\t\t\t\t\t\t\t<\/center><br \/>Bron: <a content=\"nofollow\" rel=\"nofollow\" href=\"https:\/\/3dnews.ru\/986796\">3dnews.ru<\/a><\/p>","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"excerpt":{"rendered":"<p>\u0418\u0441\u043f\u043e\u043b\u044c\u0437\u043e\u0432\u0430\u043d\u0438\u0435 3D-\u043f\u0435\u0447\u0430\u0442\u0438 \u0443\u0436\u0435 \u043d\u0438\u043a\u043e\u0433\u043e \u043d\u0435 \u0443\u0434\u0438\u0432\u043b\u044f\u0435\u0442. \u041f\u0435\u0447\u0430\u0442\u0430\u0442\u044c \u043f\u0440\u0435\u0434\u043c\u0435\u0442\u044b \u043c\u043e\u0436\u043d\u043e \u0434\u043e\u043c\u0430 \u0438 \u043d\u0430 \u0440\u0430\u0431\u043e\u0442\u0435 \u043a\u0430\u043a \u0438\u0437 \u043c\u0435\u0442\u0430\u043b\u043b\u0430, \u0442\u0430\u043a \u0438 \u0438\u0437 \u043f\u043b\u0430\u0441\u0442\u0438\u043a\u0430. \u041e\u0441\u0442\u0430\u043b\u043e\u0441\u044c \u0442\u043e\u043b\u044c\u043a\u043e \u0441\u043d\u0438\u0436\u0430\u0442\u044c \u0440\u0430\u0437\u0440\u0435\u0448\u0435\u043d\u0438\u0435 \u0440\u0430\u0431\u043e\u0442\u044b \u0441\u043e\u043f\u0435\u043b \u0438 \u043f\u043e\u0432\u044b\u0448\u0430\u0442\u044c \u0440\u0430\u0437\u043d\u043e\u043e\u0431\u0440\u0430\u0437\u0438\u0435 \u0438\u0441\u0445\u043e\u0434\u043d\u044b\u0445 \u043c\u0430\u0442\u0435\u0440\u0438\u0430\u043b\u043e\u0432. \u0418 \u0432 \u043a\u0430\u0436\u0434\u043e\u043c \u0438\u0437 \u044d\u0442\u0438\u0445 \u043d\u0430\u043f\u0440\u0430\u0432\u043b\u0435\u043d\u0438\u0439 \u0435\u0449\u0451 \u043f\u0440\u0435\u0434\u0441\u0442\u043e\u0438\u0442 \u0441\u0434\u0435\u043b\u0430\u0442\u044c \u043e\u0447\u0435\u043d\u044c \u0438 \u043e\u0447\u0435\u043d\u044c \u043c\u043d\u043e\u0433\u043e. \u041e\u0447\u0435\u0440\u0435\u0434\u043d\u044b\u043c \u0434\u043e\u0441\u0442\u0438\u0436\u0435\u043d\u0438\u0435\u043c \u0432 \u0441\u043e\u0432\u0435\u0440\u0448\u0435\u043d\u0441\u0442\u0432\u043e\u0432\u0430\u043d\u0438\u0438 3D-\u043f\u0435\u0447\u0430\u0442\u0438 \u043f\u043e\u0445\u0432\u0430\u0441\u0442\u0430\u043b\u0438\u0441\u044c \u0443\u0447\u0451\u043d\u044b\u0435 \u043f\u043e\u0434 \u0440\u0443\u043a\u043e\u0432\u043e\u0434\u0441\u0442\u0432\u043e\u043c \u0438\u0441\u0441\u043b\u0435\u0434\u043e\u0432\u0430\u0442\u0435\u043b\u0435\u0439 \u0438\u0437 [&hellip;]<\/p>\n","protected":false,"gt_translate_keys":[{"key":"rendered","format":"html"}]},"author":1,"featured_media":24737,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[702],"tags":[],"class_list":["post-32978","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-news"],"aioseo_notices":[],"aioseo_head":"\n\t\t<!-- All in One SEO 5.0.3 -
