Uma sikhuluma ngemboni yamanje, akunakwenzeka ingasaphathwa eyokuthi ukukhiqizwa okungeziwe kwama-polymer Sekushintshe ekubeni yisifiso sokwenza izithombe kwaba yisona sizathu soguquko lwezobuchwepheshe lwangempela. Akusekho nje ukwengeza ungqimba ngengqimba, kodwa kumayelana namandla anonya okwenza thuthukisa izinqubo zokukhiqiza kanye nokuklama izingxenye ezazingenakwenzeka ngaphambilini ukukhiqiza ngezindlela zendabuko.
Iqiniso liwukuthi sisesimeni esimnandi lapho kuhlangana khona ne- Imboni 4.0Ubuhlakani bokwenziwa kanye ne-Big Data kwenza izinkampani zikwazi ukuthatha isinyathelo sokufinyelela ekusetshenzisweni kwedijithali okuphelele. Akukhona nje ukuphrinta kwe-3D; kumayelana nokushintsha indlela yokucabanga yokuklama ukuze kufezwe ukusebenza kahle okungakaze kubonwe ngaphambili ochungechungeni lokuhlinzeka kanye nasekudalweni kwemikhiqizo yokugcina.
Ubuchwepheshe Obusezingeni Eliphezulu Ekushiseni Nama-Resins
Ngaphakathi kwe-ecosystem ye-laser sintering, lokho okubizwa ngokuthi Ubuchwepheshe Bokundizaokuyisizukulwane esisha sama-laser asheshayo. Ngokungafani nezinhlelo ezindala ezazisebenzisa ama-laser e-COâ‚‚, lawa asebenzisa ama-laser efayibha enamandla kakhulu, okungagcini nje ngokusheshisa inqubo kodwa futhi kuthuthukisa imbuyiselo yokutshalwa kwezimali ngoba i-laser ihlala isikhathi eside kakhulu. Njengoba ijubane lokuskena lidlula ama-20 m/s, umkhiqizo wokukhiqiza ikhuphukela emazingeni e-stratosphere.
Ngakolunye uhlangothi, sinezinhlelo zezimboni ezifana nalezo ezivela ku-EOS, ezivumelana nobukhulu bebhizinisi. Kusukela emishinini emincane kuya izixazululo ze-laser ezimbili ezisheshayo kakhulu ukuze kukhiqizwe ngobuningi. Iphuzu elibalulekile lapha ukuthi ubuchwepheshe obufana ne-SLS (Selective Laser Sintering) kanye ne-FDR abudingi ama-binding agents, okuqinisekisa ukuthi ukuhambisana kwezinto eziphilayo kanye nokuqina kwazo ukuthi izingcezu aziphazamiseki ngamakhemikhali angaphandle.
Emkhakheni wama-resin, I-EstereolitographÃa (SLA) Futhi i-Digital Light Projection (DLP) yizona eziyinhloko. Nakuba i-SLA isebenzisa i-laser enembile ukwelapha i- I-resin yoketshezi kuye ngohlobo lwezintoI-DLP iveza isithombe esiphelele sesendlalelo, esisheshisa umsebenzi. Lawa masu alungele ukufeza ukuqedwa okunencazelo ephezulu kanye nemininingwane ecishe ibe mincane kakhulu, into ebalulekile ekwakhiweni kwezakhiwo noma kwezokwelapha.
Izinto Ezithuthukisiwe kanye Nomlingo Wezinhlanganisela
Asisaneliseki ngepulasitiki eyisisekelo. Manje umdlalo useku- izinto ezihlanganisiweUkusetshenziswa kwama-polymer aqiniswe nge-carbon fiber kubalulekile emkhakheni wezindiza kanye nezimoto, njengoba evumela ukudalwa kwezingxenye ezikhona ilula kakhulu kodwa inamandla kakhuluukunciphisa isisindo semoto iyonke ngaphandle kokulahla ukuphepha.
Izinto zokwakha nazo ziyavela inkumbulo yomumo kanye nama-resin asebenzayo aklanywe ngokwenziwa kwawo kwamakhemikhali. Futhi uma sikhuluma ngamandla, ukwengeza i-graphene esebenzayo Kuma-resin, kuvumela ukuthuthuka okukhulu kwezakhiwo zomzimba nezamakhemikhali, okuholela ezingxenyeni ezingamelana nokucindezeleka okukhulu kakhulu kwemishini.
Asikwazi ukukhohlwa ukuphrinta kwezinto eziningiCabanga ngokukhiqiza ingxenye eyodwa enendawo eqinile yokuthwala imithwalo kanye nendawo eguquguqukayo yokumunca imithelela, konke kumjikelezo ofanayo wokuphrinta. Lokhu kuqeda isidingo sokuhlanganisa izingxenye ezahlukene futhi kuvumela ukudalwa amadivayisi aguquguqukayo, ikakhulukazi ezisetshenziswayo zezokwelapha okumele zilingise ukuziphatha komzimba womuntu.
Izicelo Zomhlaba Wangempela: Kusukela Emkhakheni Wezimoto Kuya Elabhorethri
Embonini yezokuthutha, ukukhiqizwa kwezinto ezengeziwe sekuyindlela evelele yokuzithuthukisa. Ithuluzi ElisebenzayoEsikhundleni sokulinda amasonto ukuthi umhlinzeki wangaphandle akhiqize isikhunta noma amathuluzi, izinkampani ziyakwenza lokho. Endlini usebenzisa i- Ukuphrinta kwe-3D kwezimotoLokhu kunciphisa izingozi futhi kuvumela noma yimaphi amaphutha okuklama ukuthi alungiswe zingakapheli amahora.
Indlela yokwamukelwa ivame ukulandela amazinga amahlanu: kuqala ngo prototyping okusheshayo, okuhlanganisa usizo lokukhiqiza, ukushintshwa kwezingxenye ezisebenzayo, ukulungiswa kwe-topological (ukunciphisa isisindo) kanye nokugcina ngezingxenye imisebenzi eminingiIsibonelo esicacile yiTesla, esebenzisa lo mqondo ukuhlanganisa imisebenzi eminingi engxenyeni eyodwa yeshasi.
Ezindaweni zocwaningo, njenge-3DLab, imingcele emangalisayo iyahlolwa. Kusukela ku- ukuphrinta nge-bio-inki ukudala izinto ezimunca izinto eziphilayo ezihlanza umoya namanzi, kuze kube yilapho kusetshenziswa amaphrinta e-liquid aqinile (i-DIW) ukuthuthukisa i-photocatalytic ceramics. Isihluthulelo lapha yikhono lokwenza yakha ama-resin akho ngezidingo ezikhethekile kakhulu.
Ukusimama, Ukuvuselela kanye Nefomethi Enkulu
Ukuzinza akuseyona inketho, kuyisidingo. Umsebenzi omningi uyenziwa e- ukuvuselelwa kwe-thermoplastics njenge-ABS noma i-PLA. Ngisho namapulasitiki okupakisha ezimboni asetshenziswa njengezinto zokusetshenziswa ezishibhile zezinqubo zokukhipha. Ukukhiqiza okungeziwe, ngokwemvelo, kunobungani nemvelo kunokukhiqiza okuncishisiwe, njengoba kunciphisa imfucuza yezinto ezibonakalayo kufika ku-30%.
Ezingxenyeni ezidinga ubukhulu bezimboni, i-pellet extrusion yokuphrinta kwe-3D Lesi yisisombululo. Esikhundleni sokusebenzisa i-filament, ebiza kakhulu, le mishini isebenzisa ama-pellet epulasitiki (impahla), okunciphisa kakhulu izindleko. Lokhu kuvumela ukuphrinta izibunjwa zefomethi enkulu kuma-bumper emoto noma kuma-dashboard, okufinyelela umthamo wokufaka ofinyelela kumakhilogremu angu-13 ezinto ngehora.
Ukuphathwa kwempahla yobuhlakani nakho sekuthuthukile. Manje sekukhona amamodeli e-3D abethelwe lapho ilayisensi ilawula ukuthi zingaki izingxenye ezingaphrintwa. Lokhu kuvumela izinkampani ezifana neDaimler ukuthi zisakaze izingxenye zazo ezisele ngendlela ehlukaniswe ngaphandle kokwesaba ukuthi imiklamo yazo izophazamiseka. okuphangiwe noma okuguquliwe ngaphandle kwemvume.
Ukuhlanganiswa kwalezi zobuchwepheshe, kanye nekhono lokudala izinqolobane zedijithali, kwenza kube lula ukukhiqizwa okuguquguqukayo nokusebenza kahle. Ekugcineni, inani langempela alikho nje kuphela ezindleko zengxenye, kodwa futhi nasezindleko ukonga isikhathi kanye nokuthuthaukuqeda ukuncika ezimpahleni ezibizayo kanye nezikhathi zokulinda ezinde ezishiya imishini ekhiqizayo ingasebenzi.
