Ukuphrinta kwensimbi 3D

Muva nje, senze umboniso wensimbiUkuphrinta 3d, futhi sayiqeda ngempumelelo kakhulu, ngakho-ke yini insimbiUkuphrinta 3d? Yini izinzuzo zayo nokubi kwayo?

Ukuphrinta kwensimbi 3D kungubuchwepheshe bokukhiqiza ongezansi olwakha izinto ezinobukhulu obuthathu ngokungeza i-metal izinto ungqimba ngesendlalelo. Nasi isingeniso esinemininingwane yokuphrinta kwe-Metal 3D:

Umgomo wobuchwepheshe
Ukukhetha i-laser isono (SLS): Ukusetshenziswa kwemigqa yamandla e-Loser Energy ukuncibilika okukhethiwe kanye ne-winter metal powders, ukuze izibopho ze-metallurgical phakathi kwezinhlayiya ze-powder zakhiwe, ngaleyo ndlela zakha ungqimba lwento ngesendlalelo. Enqubweni yokuphrinta, ungqimba olufana lomfaniswano we-powder wensimbi luqale ukufakwa endaweni yokuphrinta, bese kuba novalo lwe-laser luskena i-powder ngokuya ngesigaba sesigaba sento, ukuze i-powder eskena inyuke futhi ihlanganise ndawonye, ​​ngemuva kwe Ukuqedwa kwengqimba yokuphrinta, ipulatifomu yehla ibanga elithile, bese isakaza ungqimba olusha lwe-powder, phinda inqubo engenhla kuze kube yilapho yonke into iphrintiwe.
Ukuqothuka kwe-laser ekhethiwe (SLM): okufana ne-SLS, kepha ngamandla we-laser aphezulu, i-wetal powder ingancibilika ngokuphelele ukwakha isakhiwo se-denser, ukuqina okuphezulu kanye namandla angcono wezingxenye zensimbi ziphakeme, zisondele noma zidlula izingxenye ezikhiqizwa yinqubo yendabuko yokukhiqiza. Ilungele ukukhiqiza izingxenye e-aerospace, imishini yezokwelapha kanye nezinye izinkambu ezidinga ukunemba okuphezulu nokusebenza.
I-Electron beam incibilika (EBM): Ukusetshenziswa kwemishayo ye-elektroni njengomthombo wamandla wokuncibilika kwensimbi powders. Ugongolo lwe-elektroni lunezici zobunzima obuphakeme wamandla kanye nesivinini esikhulu sokuskena, esingancibilika ngokushesha i-wetal powder futhi sithuthukise ukusebenza kahle kokuphrinta. Ukuphrinta endaweni ye-vacuum kungakugwema ukusabela kwezinto zensimbi nge-oxygen ngesikhathi senqubo yokuphrinta, efanelekile ukuphrinta i-titanium alloy, okuvame ukuzwela e-aerospe, imishini yezokwelapha nokunye okuphezulu - Izinkambu.
Ukukhishwa Kwezinto Ezisetshenziswayo Zensimbi (Me): Indlela yokukhiqiza esekwe ezibonakalayo, ngekhanda lokukhishwa ukuze lehlise impahla yensimbi ngesililika noma unamathisele, futhi ngasikhathi sinye ukushisa nokuphulukisa, ukuze ufinyelele ungqimba ngokubumba okuqongelelwa kwesendlalelo. Uma kuqhathaniswa nobuchwepheshe be-laser ukuncibilika, izindleko zokutshala imali ziphansi, zivumelana nezimo futhi zilula, zilungele kakhulu ukuthuthukiswa kwangaphambi kwendawo yehhovisi kanye nemvelo yezimboni.
Izinto ezijwayelekile
I-Titanium Alloy: Inezinzuzo zamandla aphezulu, ukumelana okuphansi, ukumelana kahle nokugqwala okuhle, okusetshenziswa kabanzi e-aerospace, imishini yezokwelapha, izimoto kanye nezinye izinkambu, ezinamalungu endiza kanye nezinye izingxenye zokukhiqiza.
Insimbi Engagqwali: Inokumelana kahle nokugqwayiza, izakhiwo zemishini kanye nokucubungula izakhiwo, izindleko eziphansi, kungenye yezinto ezisetshenziswayo ezisetshenziselwa izingxenye zensimbi, zingasetshenziswa ukwenza izingxenye ezahlukahlukene zemishini, amathuluzi, amadivaysi ezokwelapha nokunye.
I-Aluminium Alloy: Ubuningi obuphansi, amandla aphezulu, ukuqhutshwa okuhle okushisayo, okulungele izingxenye zokukhiqiza ngezidingo eziphakeme zesisindo, njenge-cylinder yesilinda sezimoto, izingxenye zesakhiwo se-aerospace, njll.
I-Allel-based Alloy: Ngamandla amakhulu okushisa aphezulu, ukumelana nokugqwala kanye nokumelana no-oxidation, kuvame ukusetshenziselwa ukwenziwa kwezinto zokushisa eziphakeme njengezinjini zezindiza kanye ne-turbines yegesi.
imbuyiselo
I-High Digree of Design Freedom: Ikhono lokufeza ukwenziwa kwezimo eziyinkimbinkimbi, njengezakhiwo ze-lattice, izakhiwo ezenziwe ngezobuchwepheshe, njll. futhi ingakhiqiza izingxenye ezilula, eziphakeme zokusebenza.
Yehlisa inani lezingxenye: Izingxenye eziningi zingahlanganiswa zizonke, zinciphisa ukuxhumana nenqubo yomhlangano phakathi kwezingxenye, zithuthukise ukusebenza kwezingxenye, zinciphise izindleko, kepha zithuthukisa ukuthembeka nokuqina komkhiqizo.
I-PrototyPhing esheshayo: Ingakhiqiza i-prototype yomkhiqizo ngesikhathi esifushane, isheshise umjikelezo wokuthuthukiswa komkhiqizo, ukunciphisa izindleko zokucwaninga nezindleko zokuthuthukisa, kanye namabhizinisi okusiza ukuletha imikhiqizo ezimakethe ngokushesha.
Ukukhiqizwa okwenziwe ngokwezifiso: Ngokusho kwezidingo ngazinye zamakhasimende, imikhiqizo eyingqayizivele ingenziwa ukuze ihlangabezane nezidingo ezikhethekile zamakhasimende ahlukene, alungele izimila zezokwelapha, ubucwebe kanye nezinye izinkambu ezenziwe.
Ukukhawulelwa
Ikhwalithi ephezulu yendawo empofu
Iziphambeko Zangaphakathi: Kungaba neziphambeko zangaphakathi ezinjenge-pores, izinhlayiya ezingafakwanga, kanye ne-fusion engaphelele ngesikhathi senqubo yokuphrinta, ikakhulukazi ekusetshenzisweni komthwalo ophakeme kanye nomthwalo we-cyclic, kuyadingeka ukunciphisa ukwenzeka Okwehluleka kwangaphakathi ngokwandisa amapharamitha wokuphrinta nokwamukela izindlela ezifanele zokucubungula.
Ukulinganiselwa Kwezinto Ezibonakalayo: Yize izinhlobo zezinto zokuphrinta zensimbi zensimbi ezitholakalayo ziyanda, kusekhona ukulinganiselwa okuthile okubonakalayo okuqhathaniswa nezindlela zokukhiqiza zendabuko, futhi ezinye izinto zensimbi eziphakeme zinzima ukuphrinta nezindleko ziphakeme.
Izinkinga zezindleko: Izindleko zemishini yokuphrinta yensimbi ye-Metal 3D nezinto zokwakha ziphezulu futhi ijubane lokuphrinta lihamba kancane, elingeyona eyabiza kakhulu njengezindlela zokukhiqiza zendabuko zokukhiqiza okukhulu, futhi okwamanje zilungele i-batch encane, ukukhiqizwa okwenziwe ngezifiso kanye nezindawo ezinokusebenza okuphezulu komkhiqizo kanye nezidingo zekhwalithi.
Ubuchwepheshe Bokubukwa: Ukuphrinta kwensimbi 3D kufaka phakathi amapharamitha ayinkimbinkimbi kanye nokulawulwa kwenqubo, okudinga abahlinzeki bobuchwepheshe kanye nokusekelwa kwezobuchwepheshe, futhi kudinga izinga eliphakeme lobuchwepheshe kanye nesipiliyoni sabasebenza.
Inkambu yesicelo
I-Aerospace: Isetshenziselwa ukukhiqiza ama-blade e-Aero-Injini, ama-turbine disc, izakhiwo zephiko, izingxenye ze-satellite, njll., Ezinganciphisa isisindo sezingxenye, zithuthukise ukusebenza okuphezulu, futhi ziqinisekise ukusebenza okuphezulu kanye nokwethenjwa kwezingxenye.
I-AutoMobile: Ukukhiqiza izimoto isilinda se-cylinder cylinder, amagobolondo okuhambisa, izingxenye ezingasindi zesakhiwo, njll., Ukufinyelela ukwakheka okungasindi kwezimoto, ngcono ezomnotho kanye nokusebenza kophethiloli.
Ezokwelapha: Ukukhiqizwa kwamadivayisi wezokwelapha, amalunga okufakelwa, amazinyo ama-orthotic, amadivaysi ezokwelapha angenakufinyeleleka, njll.
Ukukhiqiza isikhunta: Izikhunta zokuthengisa ezikhiqizayo, isikhunta sokudla, njll., Shintsha izindleko zokukhiqiza, ukunciphisa izindleko, ukuthuthukisa ukunemba okubumba.
Ama-elekthronikhi: ama-radiator ekhiqize, amagobolondo, amabhodi wesekethe e-elekthronikhi, njll., Ukuthola ukukhiqizwa okuhlangene kwezakhiwo eziyinkimbinkimbi, kuthuthukisa ukusebenza kanye nomphumela wokudicilela phansi kwemishini kagesi.
Ubucwebe: Ngokuya ngobuhlakani bomqambi kanye nezidingo zamakhasimende, ubucwebe obuhlukile obuhlukile bungakhiwa ukuze kuthuthukiswe ukusebenza kahle kokukhiqiza kanye nokwenza okuthandwa nguwe komkhiqizo.
