Metal 3D bugu fasahar fodagyare-gyaren tsari taƙaitawa, zafi bayanai, a matsayin mafi muhimmanci na karfe sassa 3D bugu masana'antu sarkar, shi ne kuma mafi girma darajar. A taron masana'antar bugu na 3D na duniya na 2013, manyan masana a masana'antar bugu na 3D ta duniya sun ba da cikakkiyar ma'anar 3D bugu na foda, wato, girman kasa da 1mm na barbashi na karfe. Ya haɗa da foda na ƙarfe ɗaya, foda foda da wasu foda mai ƙima tare da kayan ƙarfe. A halin yanzu, 3D bugu karfe foda kayan sun hada da cobalt-chromium gami, bakin karfe, masana'antu karfe, tagulla gami, titanium gami da nickel-aluminum gami. Amma 3D buga karfe foda dole ne ba kawai mallaki kyau plasticity, amma kuma hadu da bukatun lafiya barbashi size, kunkuntar barbashi size rarraba, high sphericity, mai kyau fluidity da high sako-sako da yawa. Saboda buƙatun daban-daban na aikace-aikacen da tsarin gyare-gyare na gaba, hanyoyin shirye-shiryen na foda na karfe kuma sun bambanta. Dangane da tsarin shirye-shiryen, galibi ya haɗa da hanyar sinadarai ta jiki da hanyar injina. A cikin masana'antar ƙarfe na Foda, ana amfani da hanyoyin kamar electrolysis, raguwa da atomization. Duk da haka, ya kamata a lura cewa duka hanyoyin suna da iyakokin su, ba dace da shirye-shiryen foda foda ba. A halin yanzu, karfe foda don ƙari masana'antu ne yafi mayar da hankali a titanium gami, high zafin jiki gami, cobalt-chromium gami, high ƙarfi karfe da mutu karfe. Domin saduwa da buƙatun ƙari masana'antu kayan aiki da kuma tsari, da karfe foda dole ne a sami halaye na low abun ciki na oxygen da nitrogen, mai kyau mai siffar zobe digiri, kunkuntar barbashi size rarraba kewayon da high sako-sako da yawa. A halin yanzu, manyan hanyoyin da ake shirya foda na karfe don masana'antar ƙari sune plasma rotating electrode (PREP) , plasma atomization (PA) , gas atomization (GA) da plasma spheroidization (PS) , duk ana iya amfani da su don shirya spherical ko kusa. -karafa foda
