Izixhobo zokuva, izithinteli zomlomo, izixhobo zokufakelwa kwamazinyo, kunye nezinye izakhiwo ezenzelwe wena kakhulu zihlala ziyimveliso yoshicilelo lwe-3D. Ezi zakhiwo zihlala zenziwe nge-vat photopolymerization—uhlobo loshicilelo lwe-3D olusebenzisa iipatheni zokukhanya ukuze lubumbe kwaye luqinise i-resin, umaleko omnye ngexesha.
Le nkqubo ikwabandakanya ukuprinta izixhaso zesakhiwo ezivela kwinto efanayo ukuze zibambe imveliso endaweni yayo'iprintiwe. Nje ukuba imveliso yenziwe ngokupheleleyo, izixhasi ziyasuswa ngesandla kwaye zihlala zilahlwa njengenkunkuma engasetyenziswayo.
Iinjineli zeMIT zifumene indlela yokudlula eli nyathelo lokugqibela lokugqiba, ngendlela enokukhawulezisa kakhulu inkqubo yokuprinta i-3D. Baphuhlise i-resin eguquka ibe ziintlobo ezimbini ezahlukeneyo zezinto eziqinileyo, kuxhomekeke kuhlobo lokukhanya olukhanyisa kuyo: Ukukhanya kwe-Ultraviolet kuyayiphilisa i-resin ibe yinto eqinileyo kakhulu, ngelixa ukukhanya okubonakalayo kuguqula i-resin efanayo ibe yinto eqinileyo enokunyibilika lula kwizinyibilikisi ezithile.
Iqela lityhile i-resin entsha ngaxeshanye kwiipateni zokukhanya kwe-UV ukuze zenze isakhiwo esomeleleyo, kunye neepateni zokukhanya okubonakalayo ukuze zenze isakhiwo.'izixhaso. Endaweni yokuba baqhawule ngononophelo izixhaso, bafaka nje izinto eziprintiweyo kwisicombululo esasinyibilikisa izixhaso, nto leyo eyatyhila inxalenye eqinileyo, eprintiweyo nge-UV.
Ezi zixhaso zinokunyibilika kwiintlobo ngeentlobo zezisombululo ezikhuselekileyo ekutyeni, kuquka neoyile yosana. Okubangela umdla kukuba, ezi zixhaso zinokunyibilika nakwisithako esiphambili solwelo se-resin yokuqala, njengeqhekeza lomkhenkce emanzini. Oku kuthetha ukuba izinto ezisetyenziselwa ukuprinta izixhaso zesakhiwo zinokuphinda zisetyenziswe: Nje ukuba isakhiwo siprintiwe'Xa izinto ezixhasayo zinyibilika, loo mxube ungaxutywa ngqo ube yi-resin entsha uze usetyenziswe ukuprinta iseti elandelayo yamalungu—kunye neenkxaso zazo ezinyibilikayo.
Abaphandi basebenzise le ndlela intsha ukuprinta izakhiwo ezintsonkothileyo, kuquka oololiwe bezixhobo ezisebenzayo kunye neelattices ezintsonkothileyo.
