Ufa waukadaulo wosindikiza wa zitsulo wa 3DChidule cha njira yopangira umba, chidziwitso chotentha, monga gawo lofunika kwambiri la magawo achitsulo unyolo wa makampani osindikizira a 3D, ndichonso chofunika kwambiri. Pamsonkhano wa makampani osindikiza a 3D World 3D wa 2013, akatswiri otsogola mumakampani osindikiza a 3D World adapereka tanthauzo lomveka bwino la ufa wachitsulo wosindikizidwa wa 3D, kutanthauza, kukula kwa tinthu tachitsulo tosakwana 1mm. Uwu umaphatikizapo ufa wachitsulo chimodzi, ufa wa aloyi ndi ufa wina wosakanikirana ndi chitsulo. Pakadali pano, zipangizo za ufa wachitsulo wosindikizidwa wa 3D zikuphatikizapo cobalt-chromium alloy, chitsulo chosapanga dzimbiri, chitsulo cha mafakitale, aloyi wamkuwa, aloyi wa titaniyamu ndi aloyi wa nickel-aluminium. Koma ufa wachitsulo wosindikizidwa wa 3D suyenera kukhala ndi pulasitiki wabwino kokha, komanso kukwaniritsa zofunikira za kukula kwa tinthu tating'onoting'ono, kufalikira kwa tinthu tating'onoting'ono tochepa, sphericity yayikulu, kusinthasintha kwabwino komanso kuchuluka kwakukulu kosasunthika. Chifukwa cha zofunikira zosiyanasiyana zogwiritsira ntchito ndi njira yotsatira yopangira umba, njira zokonzekera ufa wachitsulo ndizosiyana. Malinga ndi njira yokonzekera, makamaka imaphatikizapo njira ya physical chemistry ndi njira yamakina. Mumakampani opanga zitsulo za Powder, njira monga electrolysis, kuchepetsa ndi atomization zimagwiritsidwa ntchito kwambiri. Komabe, ziyenera kudziwika kuti njira zonse ziwirizi zili ndi zofooka zake, sizoyenera kukonzekera ufa wa aloyi. Pakadali pano, ufa wachitsulo wopangira zowonjezera umakhala wochuluka kwambiri mu titanium alloy, aloyi wotentha kwambiri, aloyi wa cobalt-chromium, chitsulo champhamvu kwambiri ndi chitsulo chofewa. Kuti akwaniritse zofunikira pazida zopangira zowonjezera ndi njira, ufa wachitsulo uyenera kukhala ndi mawonekedwe a mpweya ndi nayitrogeni wochepa, digiri yabwino yozungulira, kukula kwa tinthu tating'onoting'ono komanso kusasunthika kwakukulu. Pakadali pano, njira zazikulu zokonzekera ufa wachitsulo wopangira zowonjezera ndi plasma rotating electrode (PREP), plasma atomization (PA), gas atomization (GA) ndi plasma spheroidization (PS), zonsezi zingagwiritsidwe ntchito kukonzekera ufa wachitsulo wozungulira kapena wozungulira.
