3D-‧ yomshicileli metal. Nokuveliswa amanqaku metal

3D-ucofe ithathwa impumelelo zeteknoloji ephambili kunye kwindawo ebalulekileyo additive mveliso. Ngenxa ngabashicileli-ntathu amathuba amatsha kuwo onke amacandelo ezoqoqosho. Kukholelwa ukuba kwixesha elizayo, ukuze nokuba ithandwe iindlela yemveli kwimveliso (elibenze, bephosa, njalo njalo). Kweli nqaku siza kujonga oko iintsimbi 3D-ucofe kunye nobugcisa yayo engundoqo.

Yintoni 3D-umshicileli metal

Ezi oomatshini ezikhethekileyo ezivumela izinto yesinyithi, okanye idyasi iimveliso igqityiwe. Loo umshicileli "ukhula" into ebonakalayo ngokwemaleko. Oko kukuthi, kuqala kwi computer kwinkqubo zobunjineli kudala imodeli virtual imilinganiso emithathu, lize ke lahlulwe zikhabane digital. Emva kokuqalisa-up le into entloko 3D-yoshicilelo lwe umshicileli uqalisa buthi intsimbi engamanzi , okanye umgubo awunanto kuwo phakathi iqonga ushicilelo, zakha umaleko wokuqala. Lo matshini ke kusebenza inxalenye yesibini intsimbi kunye njalo njalo.

3D-‧ yomshicileli metal ikuvumela ukuba ukudala uluhlu elikhulu iimveliso kunye, ngenxa yobuchwepheshe, ingaba kufuneka ukhuphiswano iindlela classical yemveliso metal.

Ukuba uyakwazi uprinte of 3D-abashicileli?

Olu qambo yi umshicileli jikelele apho Ungasebenzisa zombini iingcali kunye abathandi eziqhelekileyo. Metalloprintery ukuze isetyenziswe ukuvelisa izibonelelo non-esezantsi, iinxalenye zoomatshini, izacholo. Baya kuvumela ukuba ukudala iimveliso zesinyithi, bexelisa isandla-zahlukane. Yaye ayifuni izixhobo ezongezelelweyo kunye neendlela.

Industrial 3D-‧ yomshicileli metal Unokude uprinte injini rocket. Ngaloo ndlela uya kuba phantse ezahlukeneyo akukho kwimveliso eyenziwe indlela yemveli. Ngenxa yoko, metalloprinter yenza umntu mihla ukwenza nayiphi na into.

3D-ishicilela ubuchwepheshe for metal

Ukuza kuthi ga ngoku, imveliso iimveliso metal kwiteknoloji ezimbini: laser kunye noshicilelo inki-jet. Zibandakanya lamination ngcembe nangokuchanekileyo etyhidiweyo, ukuba apho ukuze wamitha nani. Kwangaxeshanye, iinjineli ziye iindlela eziliqela zokuvuna.

yoshicilelo inkjet entlandlo-ntathu

Nokuveliswa kwe metal izihloko jet yenye yeendlela zindala additive mveliso. Ivumela ukusetyenziswa kakuhle zesinyithi njengoko consumables. Kodwa lo bugcisa kusebenza kuphela xa imodeli zizonke. Isibakala sokuba umshicileli 3D-inkjet ikuvumela ukuba ukushicilela izinto nayiphi na impahla enakho hlulwa ibe ngumgubo. Ngexesha yoshicilelo, zinqunqwe izinto ekrwada inxulumene neeplastikhi. Ngenxa kule iimpawu zeteknoloji kweemveliso ezigqityiweyo ayikwazi engamelanga ithathwe njenge metal ngokupheleleyo.

Ukongeza, kuyenzeka ukuba ukuguqula imifuziselo ezihlolwayo-metal ezifunyenweyo. Ukuze usebenzise le ndawo itshileyo thermal okanye kunyibilika of Polymer kunye sintering le metal olungumgubo. iimveliso metal enjalo engenamandla, ekubeni babe isakhiwo amazwe. Yongeza amandla aokusetyenziswa yi ukumitha enye ngentsimbi. Ngokomzekelo, into sentsimbi iza kuba komelela ukuba bathele yobhedu.

Le ndlela yokudala iimveliso kakhulu asetyenziswe kundikhumbuza kunye nobucwebe shishino.

indlela lamination

inkqubo lamination 3D-print kubandakanya isicelo eqongeni sheets zesinyithi ezicekethekileyo, ukusekwa laser okanye ukusika mechanical, kwaye kuncanyatheliswe ukuba bafumane imodeli-ntathu. Le ndlela ikuvumela ukuba usebenzise njenge izinto ezisetyenziswayo, nokuba metal alumuniyam eliqinileyo. izinto elaminethiweyo abanayo amandla ngesinyithi, ekubeni ingqibelelo yabo ngokusekelwe kuncanyatheliswe amaphepha connectability.

Abaxhamla kule bugcisa kucingwa ukuba iindleko aphantsi kunesiqhelo kwaye ukukwazi ukwenza iintlobo lwezinto efanayo imveliso bonke-metal. Le yoshicilelo lamination eqhelekileyo isetyenziselwa ukwenza yeziyilo.

ekuhlanganiseni sekhombuya

Le ndlela 3D-ushicilelo isekelwe ukusetyenziswa izinto ingxubevange. Extruders ziyafumaneka kwi umshicileli ayikho nako ukumelana amaqondo aphezulu. Ngoko ke, ukuba ukwenza izinto zesinyithi esulungekileyo aluminiyamu nzima. Ngenxa yoko, developers izinto baqalisa ukuvelisa izixhobo ezikhethekileyo edityanisiweyo. Umzekelo izisombululo ezinjalo kuyinto material equlathe ngumgubo thermoplastic nobhedu.

Umshicileli yale hlobo kushicilelwa izinto metal, nto leyo imbonakalo yinto enzima i iimveliso-metal yonke. Kodwa iimpawu ezibonakalayo bezinto zimbi kakhulu. Ngoko ke, Ukufikisa, Bhubane isetyenziswa kuphela nokudalwa imifuziselo, njengezikhumbuzo, izinto ingaphakathi. Ngoku iinjineli bafuna kwiindawo zoshishino apho kuvumelekileyo ukusebenzisa obu bugcisa ukuvelisa. Ngaloo ndlela, a thermoplastic kunye lokufaka sisinyithi zingasetyenziswa ukushicilela iibhodi zesokethe yombane.

Uyakhetha laser sintering kanye ngqo

Uyakhetha laser sintering ngentsimbi unako ukusebenza nje kuphela izinto ixesha elide, kodwa thermoplastic. Kukho kwenzeka ukudalwa bezinto ezintathu-ntathu ngokusebenzisa izixhobo laser ngokuthi sintering powder yesinyithi. Lidla ukunciphisa amandla laser emitters kwi izinto ebuntsimbi fusible lisetyenziswa phezu ukutyabeka. Kwiimeko ezinjalo, ngokuba nokwandisa amandla lwemveliso ogqityiweyo kufuna extra sintering kunye ukumitha zabo zesinyithi.

Umahluko le ndlela echazwe yi ngqo metal laser sintering. Lo bugcisa swi ukusebenza uhlobo nomgubo metal ecocekileyo. Ukuze kufikelelwe kule njongo, kukho amagumbi eyodwa evaliweyo ezaliswe 3D-abashicileli kunye yegesi egalelwe. Kwakhona, umatshini wokushicilela usebenzisa consumables ukufudumeza ukuya lobushushu apho linyibilike, kodwa noko ngokupheleleyo. Oku kunciphisa ixesha zokuprinta ugcine kwiinkqubo amandla laser.

Yoshicilelo laser sintering lenzeka zikhabane. Kwiqonga umsebenzi Umatshini ubangela umaleko obhityileyo ngumgubo osuke ogama amasuntswana abo sintered phakathi kwabo kunye nwebu yangaphambili. I-laser umqadi esoloko itshintsha kwawo ngokusebenzisa inkqubo yezibuko.

Laser sintering yenza kube lula ukwenza izakhiwo olunzima isekela ezongezelelweyo. Ngoko ke, lo bugcisa lisetyenziswa ukudala iindawo ngqo wayengalindelanga machining elandelayo, kwakunye ukuba nokuveliswa imifuziselo esiluqilima zintsonkothe yokuba akunakwenzeka ukwenza eyahlulayo oluqhelekileyo.

Laser sintering ivumela ukusebenza ngensimbi, aluminiyamu nickel, titanium, amatye anqabileyo kunye like. D.

laser ukukhetha kunye nomqadi electron iintsimbi nawokunyibilika

Nangona ipateni afunyenwe metal laser-sintering, zibubunjani ophezulu, kufuneka isicelo umda. Isakhiwo misindo izinto ezigqityiweyo kunciphisa amandla abo. izinto ezinjalo ukuba angakulungeli ukusetyenziswa kwimizi-mveliso, yaye ezininzi zisetyenziswa ukwenza mockups kunye AMAGQABAZA ▸. Kuba kwimveliso ixesha elide kwaye ziyamelana wayifanisa uxinzelelo, iinjineli ziye baguqula netheknoloji laser sintering indlela laser yokunyibilikisa ngqo. Oku kusekelwe unyango olomeleleyo ubushushu umgubo wentsimbi ukuze afumane into eyohlobo olulodwa. Izinto eshicilelweyo le ndlela ayilungelelani bahluka iipropati mechanical kunye yesitalato analogue eziveliswa ngendlela yesintu.

Ngaxeshanye kunye nale iteknoloji isetyenziswa electron-beam yokunyibilikisa. It ikuvumela ukuba ukwenza izinto kunye nokuchaneka efanayo nesigqibo, kodwa kuneengenelo ezithile. Ngenxa yoko, 3D-umshicileli le hlobo ngentsimbi endaweni iinkqubo esibuko electromechanical zixhotyiswe ngemipu electron. Oku kuvumela kamatshini ukusebenza ngesantya eliphezulu, nto leyo eyandisa imveliso yenkqubo ngaphandle iingxaki ezibalulekileyo. technology olunjalo okunye elihle ukuya kwimveliso yemveli mveliso ezisebenzisa izixhobo ezongezelelweyo (liziko lezonka, nokuba iimilo wabumba).

Printer laser kunye electron umqadi yokunyibilika esisetyenziselwa ukuvelisa iinxalenye iinjini jet ze turbines negesi, zitho wamathambo.

ukwakhiwa additive laser Direct

3D-‧ yomshicileli laser ngqo metal kokuyilwayo isetyenziselwa ukuze kuhlaziywe kweemveliso ezigqityiweyo. Ithekhinoloji umatshini loo kumthetho yokulahlwa kwe-amasuntswana powder ezintsimbini izabelo ezonakeleyo yenjongosenzi kunye laser yazo zavuleka. Le ndlela luphawulwa ezikhethiweyo mxinwa kwaye isetyenziswa kuphela iinjongo zoshishino.

Eziprintiweyo intloko umshicileli yale hlobo ehamba moya ezintathu ezijikelezayo malunga iasi eme nkqo. Ngenxa yoko, ukuba usebenza na engile.

oomatshini ezinjalo asetyenziswa ukuba kutywinwe iintanda koomatshini ezimbaxa kunye neemveliso ezinkulu-ubungakanani. Umzekelo, ukuba bayilungise iinjini moya.

Ixabiso 3D-yokugaya metal

Namhlanje, imarike kuyinto uluhlu olubanzi koomatshini, ukuvumela ukwenza izinto metal-ntathu. ixabiso lazo ixhomekeke uphawu nokuprinta nobuchwepheshe. Ngenxa yoko, industrial 3D-umshicileli ukusebenza zesinyithi, apho unako uprinte injini, amashumi ezixabisa amawaka eerandi. koomatshini ukuzithengela zingathengwa sitshiphu, kodwa umgangatho mveliso kuya kuba kubi. Ukusombulula le ngxaki, iinjineli abaphuhlisa 3D-umshicileli ngenxa metal, ixabiso apho liya kuba ngaphantsi kakhulu xa sikulungele ngokupheleleyo ukusetyenziswa.
