Ngokombiko we-McKinsey, ukukhiqiza okungeziwe kukleliswe endaweni yesishiyagalolunye phakathi kobuchwepheshe obuyi-12 obunomthelela ophazamisayo empilweni yomuntu, ngaphambi kwezinto ezintsha negesi ye-shale, futhi kubikezelwa ukuthi ngo-2030 ukukhiqiza okungeziwe kuzofinyelela kusayizi wemakethe olinganiselwa ku-$1 trillion. Ngo-2015, umbiko uqhubekisele phambili le nqubo, uthi ngo-2020, okungukuthi, eminyakeni emithathu kamuva, usayizi wemakethe yokukhiqiza okungeziwe ungafinyelela kunzuzo ye-550 yezigidigidi zamadola aseMelika. Umbiko kaMcKinsey awukhiqizi.

U-Lu Bingheng, isifundiswa se-Chinese Academy of Engineering kanye nomqondisi we-National Additive Manufacturing Innovation Center, usebenzise "okune nesigamu" ukuze afingqe amathemba emakethe esikhathi esizayo okukhiqiza okungeziwe.

Ingxenye engaphezu kwengxenye yenani lomkhiqizo esikhathini esizayo iklanyelwe;

Ngaphezu kwesigamu sokukhiqizwa komkhiqizo kwenziwa ngezifiso;

Ngaphezu kwengxenye yamamodeli okukhiqiza agcwele abantu;

Ngaphezu kwesigamu sezinto ezintsha zenziwa abenzi.

Ukukhiqiza okungeziwe kuwubuchwepheshe obuphazamisayo obuholela ekuthuthukisweni kwemboni yokukhiqiza. Kuwubuchwepheshe obufanele ukusekela ukusungulwa kokuqamba, ukukhiqizwa okwenziwe ngokwezifiso, ukuqamba okusha komenzi kanye nokukhiqizwa kwe-crowdsourcing. "Okubaluleke nakakhulu, ukukhiqiza okungeziwe kuwubuchwepheshe obungavamile obuvumelaniswa nezwe ezweni lami. Njengamanje, ucwaningo lwaseChina mayelana nokunyathelisa kwe-3D luhamba phambili emhlabeni."

U-Lu Bingheng uthe njengamanje, ngokwethembela emshinini omkhulu we-3D wokunyathelisa wensimbi kanye nemishini yokugaya eyakhiwe izwe lami ngokwalo, i-China isesimweni somhlaba wonke ekusetshenzisweni kwezingxenye zezindiza ezinkulu ezithwala imithwalo, futhi isebenza njengenhlangano ithimba losizo lokuqala ocwaningweni nasekuthuthukisweni kwezindiza zezempi nezindiza ezinkulu. Ngaphezu kwalokho, izingxenye ezinkulu zesakhiwo se-titanium alloy ziye zasetshenziswa ocwaningweni nasekuthuthukisweni kwegiya lokuhlalisa izindiza kanye ne-C919.

Mayelana nokusetshenziswa, umthamo wezwe lami ofakiwe wemishini yezinga lezimboni ukleliswe endaweni yesine emhlabeni, kodwa imishini edayiswayo yokunyathelisa insimbi isebuthakathaka, futhi incike kakhulu ekuthengisweni kwamanye amazwe. Kodwa-ke, ngokusho kuka-Academician Lu Bingheng, umgomo jikelele wokukhiqiza okungeziwe kwe-China ukufeza umthamo wesibili omkhulu ofakiwe emhlabeni kanye nokukhiqizwa nokuthengiswa kwemishini enkulu kunazo zonke emhlabeni phakathi neminyaka engu-5; kanye nomthamo wesibili omkhulu ofakiwe emhlabeni, amadivayisi abalulekile nobuchwepheshe bangempela, nokuthengiswa kwemishini phakathi neminyaka eyi-10. Zuza "Made in China 2025" ngo-2035.

Ukuthuthukiswa kwezimboni kuyashesha

Idatha ibonisa ukuthi isilinganiso sokukhula esimaphakathi sosayizi wemakethe wokukhiqiza okungeziwe eminyakeni emithathu edlule. Izinga lentuthuko yale mboni eShayina liphezulu kunesilinganiso somhlaba.

Izimpawu: ngokuvamile zibhekisela kulokho okwenziwayo ukulawula izinhlelo ezithile ezivamile ngaphakathi kwekhampasi

Izimpawu, ezifana nalezi: izimpawu zembali notshani, azikho izimpawu zokukhuphuka, njll. Ukwehla, kodwa emkhakheni wesevisi, izinga lokukhula lishesha kakhulu ngenxa yokuthuthukiswa kokuqashelwa kwamakhasimende. "Ikakhulukazi ekucutshungulweni komkhiqizo nasekukhiqizeni, umthamo wethu woku-oda uphindwe kabili." I-Weinan 3D Printing Industry Cultivation Base esiFundazweni sase-Shaanxi, ngokwesekwa uhulumeni wasekhaya, iguqule izinzuzo zobuchwepheshe bokuphrinta be-3D yaba izinzuzo zezimboni futhi yakhuthaza ukuthuthukiswa nokuguqulwa kwezimboni zendabuko. Isimo esijwayelekile sokubona ukuthuthukiswa kweqoqo.

Ukugxila kumqondo wokufukamela wezimboni we-"3D printing +", akukhona nje ukuthuthukisa imboni yokunyathelisa ye-3D, kodwa ukugxila ekukhiqizeni imishini yokunyathelisa ye-3D, ucwaningo nokuthuthukiswa kanye nokukhiqizwa kwezinto zensimbi zokunyathelisa ze-3D, nokuqeqeshwa. yamathalenta agxile ekusetshenzisweni kokuphrinta kwe-3D. Igxilile ezimbonini ezihamba phambili zasendaweni, ezigxile ekusetshenzisweni kwezicelo zokubonisa imboni yokuphrinta ye-3D, ukusheshisa ukuhlanganiswa kokuphrinta kwe-3D nezimboni zendabuko, nokusebenzisa uchungechunge lwamamodeli e-3D wokuphrinta + wezimboni ezifana nokuphrinta kwe-3D + ukuhamba kwezindiza, imoto, amasiko nokudala, ukusakaza, imfundo, njll., ngosizo lokuphrinta kwe-3D Izinzuzo zobuchwepheshe bokuphrinta, ukuxazulula ubunzima bezobuchwepheshe kanye nezindawo zobuhlungu zezimboni zendabuko, ukuguqula nokuthuthukisa izimboni zendabuko, futhi wethule futhi ufukamele izinhlobo ezahlukene zamabhizinisi amancane naphakathi nendawo. .

Ngokwezibalo, kusukela ngoMeyi 2017, inani lamabhizinisi selifinyelele ku-61, futhi amaphrojekthi angaphezu kuka-50 afana nesikhunta se-3D, i-3D, imishini yezimboni ye-3D, izinto ze-3D, kanye namaphrojekthi we-3D amasiko nokudala agcinwe, okulindeleke ukuthi kwenziwe. Kulindeleke ukuthi ekupheleni konyaka, isibalo samabhizinisi sidlule ku-100.

Ukwenza kusebenze uchungechunge olusha kanye nochungechunge lwezimboni

Naphezu kokuthuthuka okusheshayo kwemboni yezwe lami yokukhiqiza izithasiselo, imboni isesigabeni sokuqala sokuthuthuka futhi isenezici zesikali esiphansi. Kodwa-ke, ukuntuleka kokuvuthwa kwezobuchwepheshe, izindleko eziphezulu zokufaka isicelo, kanye nobubanzi bezicelo obuncane kubangele ukuthi imboni iyonke ibe sesimweni "sokuncane, esihlakazekile futhi esibuthakathaka". Nakuba izinkampani eziningi seziqalile ukubeka unyawo emkhakheni wokukhiqiza okungeziwe, kukhona ukuntuleka kwezinkampani ezihamba phambili I-Driven, isikali semboni sincane. Isazi uLu Bingheng uthe ngokungananaziyo njengobunye bobuchwepheshe obubalulekile benguquko yezimboni yesikhathi esizayo, ukuthuthukiswa kokukhiqiza okungeziwe kufanele kusheshiswe, ngoba ubuchwepheshe bokuphrinta be-3D busesikhathini sokuqhunyiswa kobuchwepheshe, isikhathi sokuqala kwemboni, kanye isikhathi "sokubamba" kwezinkampani. Isidingo esikhulu semakethe singaqhuba ukuthuthukiswa kobuchwepheshe kanye nenkundla yemishini, okufanele ivikelwe futhi isetshenziswe ngokugcwele ukuqondisa nokweseka ukukhiqizwa kwemishini yethu.

Manje imishini evela kwamanye amazwe "ihlasela" imakethe yaseShayina. Ngemishini yokunyathelisa yensimbi, amazwe angaphandle asebenzisa ukuthengiswa okuhlanganisiwe kwezinto, isofthiwe, okokusebenza, nezinqubo. Izinkampani zaseShayina kumele zithuthukise ubuchwepheshe obuyisisekelo kanye nobuchwepheshe bokuqala ukuze zenze ezazo ezintsha kanye namaketanga ezimboni.

Abangaphakathi embonini bathi embonini yamanje yokunyathelisa ye-3D yasekhaya, izinga lokucwaninga nokuthuthukiswa kobuchwepheshe lisetshenziswe ngokuphelele embonini, futhi impumelelo eminingi yezobuchwepheshe isesigabeni selabhorethri kuphela. Izizathu eziyinhloko zale nkinga yilezi: okokuqala, ngenxa yamazinga ahlukahlukene, ukufinyelela Iziqu aziphelele, futhi kunezithiyo ezingabonakali zokungena; okwesibili, izikhungo zocwaningo lwesayensi kanye namabhizinisi abanayo imiphumela esikalini, basesimweni sokulwa wodwa, abanalo ilungelo lokukhuluma ezingxoxweni zezimboni, futhi basesimweni esingesihle; Imboni entsha ayiqondwa kahle, futhi kukhona izindida noma ukungaqondi kahle, okuholela ekuhambeni kancane kokusetshenziswa kobuchwepheshe.

Ithrendi Yokuthuthukiswa Kwezisetshenziswa Ze-Atomization Pulverizing Esikhathini Esizayo

Kusenezingqinamba eziningi ekuqondeni ubuchwepheshe bokuphrinta be-3D kuzo zonke izici zomkhakha wokukhiqiza waseShayina. Uma sibheka isimo sangempela sokuthuthukiswa, kuze kube manje ukuphrinta kwe-3D akukafinyeleli ekuthuthukisweni kwezimboni ezivuthiwe, kusukela kumishini kuya emikhiqizweni kuya ezinsizeni ezisesigabeni "sethoyizi elithuthukisiwe". Nokho, kusukela kuhulumeni kuya kumabhizinisi e-China, amathemba okuthuthukiswa kobuchwepheshe bokunyathelisa be-3D ngokuvamile aqashelwa, futhi uhulumeni kanye nomphakathi ngokuvamile banaka umthelela wesikhathi esizayo we-3D yokunyathelisa yensimbi ye-atomization ye-pulverizing imishini yobuchwepheshe ekukhiqizeni okukhona kwezwe lami, umnotho, namamodeli wokukhiqiza.

Ngokusho kwedatha yocwaningo, okwamanje, isidingo sezwe lami sobuchwepheshe bokuphrinta be-3D asigxiliwe kumishini, kodwa sibonakala ezinhlobonhlobo zezinto ezisetshenziswayo zokuphrinta ze-3D kanye nesidingo sezinsizakalo zokucubungula i-ejensi. Amakhasimende ezimboni angamandla amakhulu ekuthengeni imishini yokuphrinta ye-3D ezweni lami. Imishini abayithengayo isetshenziswa kakhulu kwezokundiza, i-aerospace, imikhiqizo ye-elekthronikhi, ezokuthutha, ukuklama, ukusungula amasiko nezinye izimboni. Njengamanje, umthamo ofakiwe wamaphrinta we-3D emabhizinisini aseShayina cishe u-500, futhi izinga lokukhula lonyaka lingaba ngu-60%. Noma kunjalo, usayizi wemakethe wamanje ungama-yuan ayizigidi eziyi-100 kuphela ngonyaka. Isidingo esingaba khona se-R&D kanye nokukhiqizwa kwezinto zokuphrinta ze-3D sesifinyelele cishe kumayuan ayizigidi eziyizinkulungwane eziyi-1 ngonyaka. Ngokuthandwa nokuthuthuka kobuchwepheshe bemishini, isikali sizokhula ngokushesha. Ngasikhathi sinye, izinsiza zokucubungula eziphathelene nokuphrinta ze-3D zithandwa kakhulu, futhi ama-ejenti amaningi aphrinta i-3D Inkampani yezisetshenziswa ivuthwe kakhulu enqubeni ye-laser sintering kanye nokusetshenziswa kwemishini, futhi ingahlinzeka ngezinsizakalo zokucubungula zangaphandle. Njengoba intengo yesisetshenziswa esisodwa ngokuvamile ingaphezu kwama-yuan ayizigidi ezingu-5, ukwamukelwa kwemakethe akuphakeme, kodwa insizakalo yokucubungula i-ejensi ithandwa kakhulu.

Iningi lezinto ezisetshenziswa emishinini yezwe yami yokuphrinta ye-3D yensimbi yokunyathelisa i-atomization ihlinzekwa ngokuqondile ngabakhiqizi be-prototyping abasheshayo, futhi ukunikezwa okuvela eceleni kwezinto ezijwayelekile akukakaqaliswa, okuholela ezindlekweni zezinto ezibonakalayo eziphakeme kakhulu. Ngesikhathi esifanayo, alukho ucwaningo mayelana nokulungiswa kwempushana okunikezelwe ekunyatheliseni kwe-3D e-China, futhi kunezidingo eziqinile mayelana nokusabalalisa usayizi wezinhlayiyana kanye nokuqukethwe komoya-mpilo. Amanye amayunithi asebenzisa impushana yesifutho evamile esikhundleni salokho, enokungasebenzi okuningi.

Ukuthuthukiswa nokukhiqizwa kwezinto ezisebenza ngezindlela eziningi kuyisihluthulelo sentuthuko yezobuchwepheshe. Ukuxazulula izinkinga zokusebenza nezindleko zezinto zokwakha kuzothuthukisa kangcono ukuthuthukiswa kobuchwepheshe bokwenza ama-prototyping ngokushesha e-China. Njengamanje, izinto eziningi ezisetshenziswa kubuchwepheshe bezwe lami bokuphrinta be-3D bokuphrinta ngokushesha zidinga ukungeniswa zivela phesheya, noma abakhiqizi bemishini batshale amandla amaningi kanye nezimali zokuzithuthukisa, ezibizayo, okuholela ekwenyukeni kwezindleko zokukhiqiza, ngenkathi izinto zasekhaya ezisetshenziswa kulo mshini zinamandla aphansi nokunemba. . Ukwenziwa kwasendaweni kwezinto zokuphrinta ze-3D kubalulekile.

I-Titanium ne-titanium alloy powders noma izimpushana ze-nickel-based superalloy ezisekelwe ku-cobalt ezinokuqukethwe okuphansi kwe-oxygen, usayizi wezinhlayiya ezinhle kanye ne-sphericity ephezulu kuyadingeka. Usayizi wezinhlayiyana ze-powder ngokuyinhloko -500 mesh, okuqukethwe kwe-oxygen kufanele kube ngaphansi kuka-0.1%, futhi usayizi wezinhlayiyana ufana Njengamanje, i-high-end alloy powder kanye nemishini yokukhiqiza isathembele kakhulu ekuthengeni kwamanye amazwe. Emazweni angaphandle, izinto zokusetshenziswa kanye nemishini ngokuvamile kuyahlanganiswa futhi kudayiswe ukuze bathole inzuzo eningi. Uma sithatha njengesibonelo impushana esekelwe ku-nickel, izindleko zezinto ezingavuthiwe zingamayuan angu-200/kg, intengo yemikhiqizo yasekhaya ngokuvamile iwu-300-400 yuan/kg, kanti intengo yempushana ethengwa kwamanye amazwe ivamise ukuba ngaphezu kuka-800 yuan/kg.

Isibonelo, umthelela nokuvumelana nezimo kokwakheka kwempushana, okufakiwe kanye nezakhiwo ezibonakalayo kubuchwepheshe obuhlobene bemishini yokugaya i-3D yensimbi yokunyathelisa i-atomization powder. Ngakho-ke, ngenxa yezidingo zokusetshenziswa kokuqukethwe komoyampilo ophansi kanye nosayizi wezinhlayiyana ezincane eziyimpushana, kusadingeka ukwenza umsebenzi wocwaningo njengokwakheka kwe-titanium ne-titanium alloy powder, ubuchwepheshe bokugaya i-atomization powder ye-particle size powder powder, kanye umthelela wezimpawu zempushana ekusebenzeni komkhiqizo. Ngenxa yokulinganiselwa kobuchwepheshe bokugaya e-China, kunzima ukulungisa i-powder-grained powder okwamanje, isivuno se-powder siphansi, futhi okuqukethwe kwe-oxygen nokunye ukungcola kuphezulu. Ngesikhathi senqubo yokusetshenziswa, isimo sokuncibilika kwe-powder sijwayele ukungalingani, okuholela ekuquketheni okuphezulu kwe-oxide inclusions kanye nemikhiqizo ye-denser emkhiqizweni. Izinkinga eziyinhloko zezimpushana ze-alloy zasekhaya zisezingeni lomkhiqizo nokuzinza kweqoqo, okuhlanganisa: ① ukuzinza kwezingxenye zempushana (inombolo yokufaka, ukufana kwezingxenye); ② impushana ngokomzimba Ukuzinza kokusebenza (ukusabalalisa usayizi wezinhlayiyana, i-powder morphology, i-fluidity, isilinganiso esixekethile, njll.); ③ inkinga yesivuno (isivuno esincane sempushana engxenyeni yosayizi wezinhlayiyana ezincane), njll.
