Xa sithetha malunga nokuveliswa okongeziweyo kunye nezinto eziphathekayo, sihlala sicinga ngeplastiki okanye isinyithi.Nangona kunjalo,Ushicilelo lwe-3Diimveliso ezihambelanayo zikhule kakhulu kwiminyaka.Ngoku sinokusebenzisa imathiriyeli ekrwada eyohlukeneyo ukuvelisa iinxalenye, ukusuka kwi-ceramics ukuya ekutyeni ukuya kwii-hydrogels eziqulethe iiseli ze-stem.Ukhuni lukwayenye yezi nkqubo zemathiriyeli ezandisiweyo.
Ngoku, izixhobo zokhuni zinokuhambelana ne-filament extrusion kunye neteknoloji yebhedi engumgubo, kunye noshicilelo lwe-3D lwamaplanga luya luthandwa ngakumbi.
Ngokwengxelo epapashwe liphephancwadi iNature, abantu baphulukene ne-54% yenani lilonke lemithi emhlabeni.Ukutshatyalaliswa kwamahlathi kusisisongelo sokwenene namhlanje.Kubalulekile ukuba siphinde sicinge ngendlela esizisebenzisa ngayo iinkuni.Imveliso eyongeziweyo ingaba ngundoqo wokusetyenziswa kokhuni oluzinzileyo, kuba iteknoloji yokuvelisa esebenzisa kuphela izinto eziyimfuneko, kwaye inokusebenzisa izinto ezihlaziyiweyo ukuyila izinto.Ngoko ke, sinokuprinta iinxalenye ze-3D.Ukuba azisenamsebenzi, sinokuziguqula sizibuyisele kwimathiriyeli ekrwada ukuqala umjikelo omtsha wemveliso.

Umthi ogqithisiweyoUshicilelo lwe-3D inkqubo
Enye indlela yokushicilela iinkuni kwi-3D kukukhupha imicu.Kufuneka kuqatshelwe ukuba ezi zixhobo azikho i-100% eyenziwe ngamaplanga.Ngokwenene ziqulethe i-30-40% ye-fiber yomthi kunye ne-60-70% ye-polymer (esetyenziswa njenge-adhesive).Inkqubo yokuvelisa yoshicilelo lwe-3D ngokwayo nayo inomdla kakhulu.Umzekelo, unokuvavanya amaqondo obushushu ahlukeneyo ezi ngcingo ukuvelisa imibala eyahlukeneyo kunye nokugqiba.Ngamanye amazwi, ukuba i-extruder ifikelela kwiqondo lokushisa eliphezulu, i-fiber yomthi iya kutshisa, ibangele ithoni emnyama kwi-debris.Kodwa khumbula, le mathiriyeli inokutsha kakhulu.Ukuba umlomo wombhobho ushushu kakhulu kwaye isantya sokukhupha ucingo asikhawulezi ngokwaneleyo, indawo eprintiweyo inokonakala okanye ibambe umlilo.
Inzuzo ephambili yesilika yomthi kukuba ibonakala, ivakalelwa kwaye ivumba njengemithi eqinile.Ukongeza, iiprinta zinokupeyintwa ngokulula, zisikwe kwaye zipolishwe ukwenza umphezulu wazo ube yinyani ngakumbi.Nangona kunjalo, enye yezona zinto zingabonakali kakuhle kukuba yinto ebuthathaka ngakumbi kune-thermoplastic eqhelekileyo.Ngoko ke, kulula ukuwaphula.
Ngokuqhelekileyo, ezi zinto aziyi kusetyenziswa kwindawo yoshishino, kodwa kwihlabathi lomenzi, apho lisetyenziswe njengento yokuzonwabisa okanye into yokuhlobisa.Abanye abavelisi abakhulu befayibha zomthi baquka iPolymaker, iFilamentum, iColorfabb okanye iFormFutura.
Ukusetyenziswa komthi kwinkqubo yebhedi yomgubo
Ukuveliswa kweengxenye zokhuni, iteknoloji yebhedi ye powder ingasetyenziswa.Kwezi meko, kusetyenziswa umgubo omdaka kakhulu omdaka owenziwe ngesawdust, kwaye umphezulu ufana nesanti.Enye yezona teknoloji zifanelekileyo kule ntsimi kukutshiza nge-adhesive, eyona idume kakhulu kwi-Desktop Metal (DM).I-DM ivule umnyango omtsha kwilizwe lemveliso elongezelelweyo emva kokusebenzisana neForust.Inkqubo yoshicilelo ye "Shop System Forest Edition" iphuhliswe ngokudibeneyo ngamabini ivumela abaphulaphuli ababanzi ukuba basebenzise i-Binder Jetting yoshicilelo lwe-3D yomthi.
Le nkqubo yoshicilelo inoshicilelo lwe-3D olusebenzayo lwezixhobo zomthi ezenziwe ngamaplanga asetyenzisiweyo.Iteknoloji yokuvelisa ngokwenene isebenzisa amasuntswana e-sawdust kunye ne-adhesives kwinkqubo yokulawula ikhompyutha.Ukusebenzisa inkqubo yokuvelisa i-layer-by-layer, kunokwenzeka ukwenza amacandelo enkuni okunzima ukufezekisa ngeendlela zendabuko zokuthabatha kwaye azilahleki.Ngokucacileyo, ixabiso le teknoloji liya kuba liphezulu kakhulu kunendlela ye-filament extrusion.Nangona kunjalo, oku kufanelekile ukuqwalaselwa kuba isiphumo sokugqibela siya kuba nomgangatho ophezulu womphezulu kunenxalenye eprintiweyo ye-FFF.
Ukongeza kokuqwalaselwa njengemowudi yokwenziwa kweenkuni ezizinzileyo, ushicilelo lwamaplanga lwe-3D lunokusombulula iingxaki ezininzi.Oku kubandakanya ukusuka ekubuyiselweni kwembali ukuya ekudalweni kwezinto zodidi oluphezulu, ukuya kusetyenziso lwezi zinto zendalo azikayicingi imveliso emitsha.Ngenxa yokuba yinkqubo yedijithali, abasebenzisi abangenazo izakhono zokuchwela banokunandipha iingenelo zomthiUshicilelo lwe-3D.
