Ukuveliswa kwezinto ezikhaphukhaphu ezidibeneyo zineemfuno eziphezulu kwiinkalo ze-aerospace, i-automotive, kunye nokukhusela.Kule mimandla, ukunciphisa ubunzima kunye nokuqinisekisa amandla kunye nokuqina zizinto eziphambili ekugqibeni umsebenzi.Nangona kunjalo, le yinkqubo echitha ixesha kwaye ibiza kakhulu.
I-ExOne yinkampani yase-US esekwe kwi-additive production esebenza ngokukodwa kwi-3D yoshicilelo lwentsimbi kunye ne-santi binder jetting.I-ExOne ngoku iphuhlise enye indlela eyenza ukuba kwenzeke ukwenza izinto ezintsonkothileyocarbon fiber or ifayibha yeglasiiindawo eziqinisiweyo, ngaloo ndlela kuthintelwa ukusetyenziswa kwezixhobo ezixabisa kakhulu ukwakha iijiyometri ezintsonkothileyo.Oku kuthetha ukuba akukho ndlela zincedisayo ezifana nezinyibilikisi, izixhobo zokukhupha umoya, okanye iitshizili ezifunekayo.
Itekhnoloji yinkqubo yokukhuhla esebenzisa i-silica eprintiweyo ye-3D eqinileyo kodwa enyibilikayo okanye i-ceramic sand cores.Ngokweemfuno ezithile zamandla, i-3D iprinte i-arhente yokutshiza enyibilikayo emanzini okanye iTe ngaphambi kokuba i-ply composite ishiye umphezulu ngaphandle kweepores, kwaye emva koko wongeze izinto ezidibeneyo kumphezulu ngelaphu okanye i-superposition.Emva kokunyanga, izinto ezixhasayo ezinyibilikayo zihlanjululwa ngokulula ngamanzi ompompo, zishiya indawo edibeneyo edibeneyo.Kwaye imidiya enyibilikisiweyo inokuphinda isetyenziswe kwaye isetyenziswe kwakhona kushicilelo lwe-3D lwexesha elizayo.
URick Lucas, iGosa eliPhezulu lobuChwephesha be-ExOne, uthe: “Le yinto ebesisebenza ngayo ixesha elide.Le yimarike esifuna ukuyijolisa kwaye siyilandele.Sinoonjineli abasebenze kwishishini le-composites kwaye bayabaqonda abantu.Kukho imfuno enzulu yemo yemveliso edibeneyo. ”
Ukusukela ngo-2013, iinjineli ze-ExOne zifumanise okokuqala ukuba zinokubophelela isilica okanye igrit yeceramic kwisinyibilikisi esinyibilikayo emanzini kwi-180°C.Ubunzima bugxininise kwisinyathelo sokugquma kunye nokusetyenziswa kwe-adhesive jet 3D yoshicilelo ukuze kulungiswe izinto eziphathekayo.ULucas wathi: “Intlabathi yodongwe esidla ngokuyisebenzisa inemingxuma.Ngoko ukuba usasaza izinto ezidibeneyo kuyo, i-autoclave phantsi koxinzelelo kunye nobushushu, uze uyiqinise;ke i-resin iya kungena Kwizinto ezidibeneyo, ayisahlanjwa.Ngoko ke, kufuneka sisebenzise umaleko wokugquma kuwo ukuze kuthintelwe oku kungenzeki.Kulo nyaka uphelileyo, besichitha ixesha elininzi siphucula iiNdlela zokugquma kunye neenkqubo, kunye nokuqinisekisa ukuba abathengi babonelelwa ngeendlela ezifanelekileyo zokugquma.
Iindawo zokugqibela zombhobho ezenziwe ngezinto ezidibeneyo ezenziwe ngeteknoloji enyibilikayo emanzini
Namhlanje,le ndlela isetyenziselwa ukuvelisa i-carbon fiber kunye neglasi ifayibha eqinisiweyo imathiriyeli ehlanganisiweyo, kubandakanywa nemibhobho yomoya yenqwelomoya, iitanki zoxinzelelo, amakhaka, iintsika, kunye ne-mandrels, ngakumbi kuyilo olwalungafanelekanga ukuveliswa ngobugcisa bendabuko.Ngokomzekelo, i-REC, inkampani ebonelela ngemigudu yomoya yeehelikopta ezinzima, isebenzise isixhobo sokugungxulwa kwe-ExOne ukwenza i-mandrels yee-air ducts kwii-helicopter ezimbini ze-CH-35K, kwaye yazisa ngempumelelo ezi nqwelo-moya kwi-US Marine Corps ukuze zibonise.

I-ExOne iphinda izame ukujongana nomnye umngeni oqhelekileyo ekuhlangatyezwane nawo kwiinkqubo ze-autoclaving zemveli-ukwandiswa kwe-thermal kunye nefuthe layo kwinxalenye yejometri.Ngenkqubo yokugungxulwa, umgubo unokutshintshwa ukuze ulawule ukwanda kunye nokunciphisa ukuguqulwa.Ngokomzekelo, i-coefficient yokwandiswa kwe-thermal ephezulu yesanti ye-silica inokufaneleka kwezinye izinto, kodwa kwezinye iimeko apho kufuneka i-coefficient yokwandisa i-thermal ephantsi, isanti ye-ceramic ingaba yinto efanelekileyo kakhulu.
Okwangoku, obu buchwepheshe bubonelelwa ikakhulu ngokwemfuno ngeziko le-ExOne lokuthatha abantwana elise-United States.Kodwa inkampani ithe inethemba lokwandisa le misebenzi eYurophu kungekudala, kwaye inokusebenzisana namaqabane njengoko imfuno ikhula.I-ExOne ikwasebenza nzima ukuqhubela phambili nokuphucula isisombululo sokuncamathelisa ngenguqulelo yesizukulwana esilandelayo, esiya kubonelela ngamandla aphezulu, isisombululo esihle kunye nokusebenza okuphezulu kobushushu.(Umthombo: Zhongguancun Online)
