Izinsiza-kuzwa, izivikelo zomlomo, izifakelo zamazinyo, nezinye izakhiwo ezilungiselelwe kahle ngokuvamile ziyimikhiqizo yokunyathelisa kwe-3D. Lezi zakhiwo zivame ukwenziwa nge-vat photopolymerization—uhlobo lokuphrinta lwe-3D olusebenzisa amaphethini okukhanya ukuze lubumbe futhi luqinise i-resin, ungqimba olulodwa ngesikhathi.
Le nqubo ihilela nokuphrinta izisekelo zesakhiwo ezivela ezintweni ezifanayo ukuze kugcinwe umkhiqizo endaweni yawo njengoba unjalo.'s iphrintiwe. Uma umkhiqizo usuqediwe ngokuphelele, izisekelo ziyasuswa ngesandla futhi ngokuvamile ziphonswe ngaphandle njengemfucuza engasetshenziswa.
Onjiniyela be-MIT bathole indlela yokudlula lesi sinyathelo sokugcina sokuqeda, ngendlela engasheshisa kakhulu inqubo yokunyathelisa nge-3D. Bathuthukise i-resin ephenduka izinhlobo ezimbili ezahlukene zezinto eziqinile, kuye ngohlobo lokukhanya okukhanya kuyo: Ukukhanya kwe-Ultraviolet kwelapha i-resin ibe yinto eqinile kakhulu, kuyilapho ukukhanya okubonakalayo kuguqula i-resin efanayo ibe yinto eqinile encibilika kalula kwezinye izinto ezinyibilikayo.
Ithimba liveze i-resin entsha ngesikhathi esisodwa kumaphethini okukhanya kwe-UV ukuze kwakheke isakhiwo esiqinile, kanye namaphethini okukhanya okubonakalayo ukuze kwakheke isakhiwo.'izisekelo. Esikhundleni sokuphula ngokucophelela izisekelo, bamane bacwilisa izinto ezinyathelisiwe esixazululweni esasincibilikisa izisekelo, kwembulwe ingxenye eqinile, ephrintiwe nge-UV.
Izisekelo zingancibilika ezixazululweni ezahlukahlukene eziphephile ekudleni, kufaka phakathi uwoyela wezingane. Ngokuthakazelisayo, izisekelo zingancibilika ngisho nasesithakweni esiyinhloko soketshezi se-resin yokuqala, njengekhiyubhu yeqhwa emanzini. Lokhu kusho ukuthi izinto ezisetshenziselwa ukuphrinta izisekelo zesakhiwo zingaphinde zisetshenziswe: Uma isakhiwo sesiphrintiwe'Uma izinto ezisekelayo zincibilika, leyo ngxube ingahlanganiswa ngqo ibe yi-resin entsha bese isetshenziselwa ukuphrinta isethi elandelayo yezingxenye—kanye nezisekelo zazo ezincibilikayo.
Abacwaningi basebenzise le ndlela entsha ukuphrinta izakhiwo eziyinkimbinkimbi, okuhlanganisa izitimela zegiya ezisebenzayo kanye nama-lattice ayinkimbinkimbi.
