3D "saƙa" fasaha

---

Wani shahararren maƙerin Faransa ya kirkiro wata dabara ta "saƙa" ta 3D don ƙwaƙƙun zaren da ke haɗu da zaren murfin thermoplastic tare da ƙarƙƙarfan zaren carbon. Lokacin da aka warke sashin, resin thermoplastic zai zama matrix ɗin kayan, kuma zaren carbon ɗin shima a ciki. A halin yanzu, kamfanin kera injina na kasuwanci Dassault Systèmes ya yi amfani da sassan da wannan tsari ya samar akan jirgin kasuwanci na "Falcon".

Fasaha ta 3D "saƙa" sabuwar hanya ce wacce ta dogara da ci gaba da ƙwayoyin zaren ƙarfe don ƙara ingancin aiki. Fasahar tana amfani da kayan aikin da masana'anta ke gwadawa koyaushe don "haɗar" sassan haɗin thermoplastic. Fiber-ƙarfafa thermoplastic composites (amfani da su don samar da ƙarfi da ƙarfi) haɗe tare da matakan sarrafa allura, ƙwayoyin carbon unidirectional masu wuya suna hana samar da abubuwa zuwa nau'ikan siffofi masu rikitarwa, kuma gyaran ingin yana ba da ƙarin ayyuka zuwa ɓangaren. Shawo kan ƙalubalen rashin aiwatarwa saboda ƙananan fiber fiber. Dukkanin aikin anyi amfani da su ta atomatik, tare da mafi ƙarancin lokutan zagayowa fiye da sassan haɗin thermoset tare da aikin masana'antu iri ɗaya.
Fasahar "saƙa" ta 3D tana amfani da tsari wanda ba na autoclave ba, wanda hakan ya haifar da juyin juya hali a cikin tsarin masana'antun keɓaɓɓu a fagen haɗin thermoset. A al'adance, saboda amfani da autoclave yana da tsada kuma yana iyakance ingancin samarwa, shine mabuɗin don rage farashi da ingancin aikin samar da kayan haɗin.
A cikin 2015, NASA ta fara ƙoƙarinta na farko. Ya gwada wani yanki wanda ba matattara ba ne wanda ya tabbatar da wani jirgi mai hadadden jirgi ta hanyar amfani da kamfanin Boeing wanda ba na autoclave ba. A watan Afrilu na wannan shekarar, Rasha Aerospace Composites sun gabatar da akwatin farko na akwatin jirgi na jirgi na MC-21, wanda aikin ba-autoclave ya kera shi. Fatawar fikafikan jirgin sama an yi ta ne ba da autoclave ba, wanda yake babba. Jirgin saman farar hula yayi amfani da wannan fasaha a karon farko.
