Metal 3D teknoloji yosindikiza ufaakamaumba ndondomeko mwachidule, zambiri otentha, monga gawo lofunika kwambiri mbali zitsulo 3D unyolo osindikizira makampani, ndi mtengo kwambiri. Pa World 3D makampani osindikizira msonkhano 2013, kutsogolera akatswiri mu World 3D makampani osindikizira anapereka tanthauzo lomveka bwino 3d kusindikizidwa zitsulo ufa, ndiko kuti, kukula kwa zosakwana 1mm particles zitsulo. Zimaphatikizapo ufa wachitsulo umodzi, ufa wa aloyi ndi ufa wina wotsutsana ndi chitsulo. Pakali pano, 3D zosindikizira zitsulo ufa zipangizo monga cobalt-chromium aloyi, zitsulo zosapanga dzimbiri, mafakitale zitsulo, aloyi mkuwa, aloyi titaniyamu ndi faifi tambala-zotayidwa aloyi. Koma 3D kusindikizidwa zitsulo ufa sayenera kukhala ndi plasticity wabwino, komanso kukwaniritsa zofunika za kukula tinthu, yopapatiza tinthu kukula kugawa, mkulu sphericity, fluidity wabwino ndi kachulukidwe mkulu lotayirira. Chifukwa cha zofunikira zosiyanasiyana zogwiritsira ntchito ndi ndondomeko yowumba yotsatila, njira zokonzekera ufa wachitsulo ndizosiyana. Malingana ndi ndondomeko yokonzekera, makamaka imaphatikizapo njira ya chemistry ya thupi ndi njira yamakina. M'makampani a Powder metallurgy, njira monga electrolysis, kuchepetsa ndi atomization zimagwiritsidwa ntchito kwambiri. Komabe, ziyenera kudziwidwa kuti njira zonsezi zili ndi zofooka, siziyenera kukonzekera ufa wa alloy. Pakali pano, ufa wachitsulo wopangira zowonjezera umakhazikika mu titaniyamu aloyi, kutentha kwa aloyi, cobalt-chromium alloy, chitsulo champhamvu kwambiri ndi chitsulo chakufa. Pofuna kukwaniritsa zofunikira za zipangizo zowonjezera kupanga ndi ndondomeko, ufa zitsulo ayenera kukhala ndi makhalidwe otsika okhutira mpweya ndi nayitrogeni, wabwino ozungulira digiri, yopapatiza tinthu kukula kugawa osiyanasiyana ndi mkulu lotayirira kachulukidwe. Pakalipano, njira zazikulu zokonzekera ufa wachitsulo kuti mupange zowonjezera zowonjezera ndi plasma roting electrode (PREP) , plasma atomization (PA) , gas atomization (GA) ndi plasma spheroidization (PS) , zonsezi zingagwiritsidwe ntchito pokonzekera zozungulira kapena pafupi. -ufa wachitsulo wozungulira
