Uma sikhuluma ngokukhiqiza okungeziwe kanye nezinto zokwakha, ngokuvamile sicabanga ngepulasitiki noma insimbi.Nokho,Ukuphrinta kwe-3Dimikhiqizo ehambisanayo ikhule kakhulu phakathi neminyaka.Manje sesingakwazi ukusebenzisa izinto zokusetshenziswa ezihlukahlukene ukuze sikhiqize izingxenye, kusukela kobumba kuya ekudleni kuya kuma-hydrogel aqukethe ama-stem cells.Izinkuni nazo zingenye yalezi zinhlelo zempahla enwetshiwe.
Manje, izinto zokhuni zingase zihambisane ne-filament extrusion kanye nobuchwepheshe be-powder bed, futhi ukuphrinta kwe-3D kwezinkuni kuya ngokuya kuthandwa kakhulu.
Ngokombiko oshicilelwe umagazini i-Nature, abantu balahlekelwe ngamaphesenti angu-54 yenani eliphelele lezihlahla emhlabeni.Ukugawulwa kwamahlathi kuwusongo lwangempela namuhla.Kubalulekile ukucabanga kabusha indlela esidla ngayo izinkuni.Ukukhiqiza okungeziwe kungase kube ukhiye wokusetshenziswa okuzinzile kwezinkuni, ngoba ubuchwepheshe bokukhiqiza obusebenzisa izinto ezidingekayo kuphela, futhi bungasebenzisa izinto ezigaywe kabusha ukuklama izinto.Ngakho-ke, singakwazi ukuphrinta izingxenye ze-3D.Uma zingasenalo usizo, singaziguqula sizibuyisele ezintweni zokusetshenziswa ukuze siqale umjikelezo omusha wokukhiqiza.

Ukhuni olunwetshiweUkuphrinta kwe-3D inqubo
Enye indlela yokuphrinta izinkuni ku-3D ukukhipha imicu.Kumele kuqashelwe ukuthi lezi zinto azikho i-100% eyenziwe ngokhuni.Empeleni aqukethe i-30-40% ye-wood fiber kanye ne-60-70% ye-polymer (esetshenziswa njenge-adhesive).Inqubo yokukhiqiza yokuphrinta ye-3D yokhuni ngokwayo nayo iyathakazelisa kakhulu.Isibonelo, ungahlola amazinga okushisa ahlukene alezi zintambo ukuze ukhiqize imibala ehlukene kanye nokuqeda.Ngamanye amazwi, uma i-extruder ifinyelela izinga lokushisa eliphezulu, i-fiber yokhuni izoshisa, okuholela ezwini elimnyama emfucumfucwini.Kodwa khumbula, le nto ivutha kakhulu.Uma umlomo wombhobho ushisa kakhulu futhi isivinini sokukhipha ucingo singasheshi ngokwanele, ingxenye ephrintiwe ingase yonakale noma ibambe umlilo.
Inzuzo eyinhloko yosilika wezinkuni ukuthi ibukeka, izwa futhi iphunga njengokhuni oluqinile.Ukwengeza, amaphrinti angapendwa kalula, asikwe futhi acwebezeliswe ukuze enze izindawo zawo zibe ngokoqobo.Kodwa-ke, enye yezinto ezimbi ezisobala kakhulu ukuthi iyinto entekenteke kakhulu kune-standard thermoplastic.Ngakho-ke, kulula ukuphuka.
Ngokuvamile, le nto ngeke isetshenziswe endaweni yezimboni, kodwa emhlabeni umenzi, lapho isetshenziswa njengento yokuzilibazisa noma into yokuhlobisa.Abanye abakhiqizi abakhulu be-fiber fiber bahlanganisa i-Polymaker, i-Filamentum, i-Colorfabb noma i-FormFutura.
Ukusetshenziswa kokhuni ohlelweni lwe-powder bed
Ukuze kukhiqizwe izingxenye zokhuni, ubuchwepheshe be-powder bed bungasetshenziswa.Kulezi zimo, kusetshenziswa impushana enhle kakhulu ensundu eyakhiwe nge-sawdust, futhi indawo engaphezulu ifana nesihlabathi.Obunye bobuchwepheshe obufaneleka kakhulu kulo mkhakha ukufutha ngokunamathelayo, okudume kakhulu ngeDesktop Metal (DM).I-DM ivule umnyango omusha emhlabeni wokukhiqiza izithasiselo ngemuva kokubambisana neForust.Isistimu yokuphrinta ye-"Shop System Forest Edition" eyakhiwe ngokuhlanganyela yilaba ababili ivumela izethameli ezibanzi ukuthi zisebenzise i-Binder Jetting ekuphrinteni kwe-3D yokhuni.
Lolu hlelo lokuphrinta lungaphrinta nge-3D izingxenye ezisebenzayo zokhuni ezenziwe ngokhuni olugaywe kabusha.Ubuchwepheshe bangempela bokukhiqiza busebenzisa izinhlayiya ze-sawdust kanye nama-adhesives ohlelweni lokulawula ikhompyutha.Ukusebenzisa uhlelo lokukhiqiza ungqimba nge-layer, kungenzeka ukudala izingxenye zokhuni okunzima ukuzifeza ngezindlela zendabuko zokususa futhi ezingenamsebenzi.Ngokusobala, intengo yalobu buchwepheshe izoba phezulu kakhulu kunendlela ye-filament extrusion.Kodwa-ke, lokhu kufanele kucatshangelwe ngoba umphumela wokugcina uzoba nekhwalithi ephezulu ephezulu kunengxenye ephrintiwe ye-FFF.
Ngaphezu kokubhekwa njengemodi yokukhiqiza izinkuni esimeme, ukuphrinta kwezinkuni ze-3D nakho kungaxazulula izinkinga eziningi.Lokhu kuhlanganisa kusukela ekubuyiselweni komlando ekudalweni kwezimpahla zokunethezeka, ukusetshenziswa kwalezi zinto zemvelo azikacabangi imikhiqizo emisha.Ngenxa yokuthi kuyinqubo yedijithali, abasebenzisi abangenawo amakhono okubaza bangajabulela izinzuzo zokhuniUkuphrinta kwe-3D.
