Kudhinda kwe3D tekinoroji inotonhorera uye inoshanda zvakasiyana-siyana ine mashandisirwo akawanda. Zvisinei, kusvika pari zvino, kwave kuchingogumira pachinhu chimwe chete - saizi yeprinta ye3D.
Izvi zvinogona kuchinja munguva pfupi iri kutevera. Chikwata cheUC San Diego chakagadzira furo rinogona kukura kusvika pa40 pane raive repakutanga.
"Mukugadzirwa kwemazuva ano, chirambidzo chinogamuchirwa ndechekuti zvikamu zvinogadzirwa uchishandisa maitiro ekuwedzera kana ekubvisa (senge machira, zvigayo, kana maprinta e3D) zvinofanirwa kunge zvidiki pane michina pachayo inoagadzira. Zvinofanira kunge zviri zvidiki pane michina inoagadzira. Zvinofanira kunge zvakasungirirwa, zvakasungirirwa, zvakasungirirwa kana kunamirwa kuti zvigadzire zvivakwa zvakakura."
"Takagadzira resin yakagadzirwa nefuro yekugadzirwa kwekuwedzera kwe lithographic iyo inogona kuwedzera mushure mekudhinda kuti igadzire zvikamu zvinosvika ka40 kupfuura huwandu hwepakutanga. Zvivakwa zvakasiyana-siyana zvinozvigadzira."
Kutanga, timu yakasarudza monomer yaizova chivako chepolymer resin: 2-hydroxyethyl methacrylate. Vakazofanira kutsvaga huwandu hwakakwana hwephotoinitiator pamwe chete nechinhu chakakodzera chekuputira kuti chisanganiswe ne2-hydroxyethyl methacrylate. Mushure mekuyedza kwakawanda, timu yakasarudza chinhu chisiri chetsika chekuputira chinowanzo shandiswa nemapolymers ane polystyrene.
Mushure mekunge vawana resin yekupedzisira ye photopolymer, timu ye3D yakadhinda madhizaini akareruka eCAD ndokuadziisa kusvika ku200°C kwemaminitsi gumi. Mhedzisiro yekupedzisira yakaratidza kuti chivakwa chacho chakawedzera ne4000%.
Vaongorori vanotenda kuti tekinoroji iyi inogona kushandiswa muzvinhu zvakareruka zvakaita sema airfoils kana zvinhu zvinobatsira pakubhururuka, pamwe nekushandisa zvinhu zvakaita semuchadenga, simba, kuvaka uye zvekurapa. Chidzidzo ichi chakaburitswa muACS Applied Materials & Interface.
