Kusindikiza kwa 3D ndi ukadaulo wabwino komanso wosinthasintha womwe umagwiritsidwa ntchito mosiyanasiyana. Komabe, mpaka pano, wakhala ndi chinthu chimodzi chokha - kukula kwa chosindikizira cha 3D.
Izi zitha kusintha posachedwa. Gulu la UC San Diego lapanga thovu lomwe limatha kukula mpaka kuwirikiza nthawi 40 kukula kwake koyambirira.
"Mu kupanga kwamakono, choletsa chovomerezeka ndichakuti zida zopangidwa pogwiritsa ntchito njira zowonjezera kapena zochotsera (monga ma lathe, mphero, kapena makina osindikizira a 3D) ziyenera kukhala zazing'ono kuposa makina omwe amapanga makinawo. Ziyenera kukhala zocheperako kuposa makina omwe amazipanga. Zomangiriridwa, Zolungidwa kapena Zomatidwa kuti zipange nyumba zazikulu."
"Tapanga utomoni wa prepolymer wopangidwa ndi thovu wopangira zowonjezera za lithographic zomwe zimatha kukula pambuyo posindikiza kuti zipange zigawo mpaka kuwirikiza nthawi 40 kuposa voliyumu yoyambirira. Kapangidwe kangapo kamene kamazipanga."
Choyamba, gululo linasankha monomer yomwe ingakhale maziko a utomoni wa polymer: 2-hydroxyethyl methacrylate. Kenako anayenera kupeza kuchuluka kwabwino kwa photoinitiator komanso chopangira mpweya choyenera kuphatikiza ndi 2-hydroxyethyl methacrylate. Pambuyo poyesa kambiri, gululo linasankha chopangira mpweya chomwe sichinali chachikhalidwe chomwe chimagwiritsidwa ntchito kwambiri ndi ma polima okhala ndi polystyrene.
Atamaliza kupeza utomoni womaliza wa photopolymer, gulu la 3D linasindikiza mapangidwe osavuta a CAD ndikuwotcha mpaka 200°C kwa mphindi 10. Zotsatira zomaliza zinasonyeza kuti kapangidwe kake kanakula ndi 4000%.
Ofufuzawo akukhulupirira kuti ukadaulowu tsopano ungagwiritsidwe ntchito pazinthu zopepuka monga ma airfoil kapena zothandizira kuyenda, komanso ntchito zoyendera ndege, mphamvu, zomangamanga ndi zamankhwala. Kafukufukuyu adasindikizidwa mu ACS Applied Materials & Interface.
