Foda fasahar buga ƙarfe ta 3DTakaitaccen bayani game da tsarin ƙira, bayanai masu zafi, a matsayin mafi mahimmancin ɓangaren masana'antar buga takardu ta ƙarfe 3D, shi ma shine mafi girman ƙima. A taron masana'antar buga takardu ta duniya na 2013, manyan ƙwararru a masana'antar buga takardu ta 3D ta duniya sun ba da ma'anar foda na ƙarfe mai bugawa na 3D, wato, girman ƙasa da 1mm na ƙwayoyin ƙarfe. Ya haɗa da foda na ƙarfe ɗaya, foda na ƙarfe da wasu foda mai hana ruwa tare da kadarar ƙarfe. A halin yanzu, kayan foda na ƙarfe mai bugawa na 3D sun haɗa da ƙarfe na cobalt-chromium, bakin ƙarfe, ƙarfe na masana'antu, ƙarfe na tagulla, ƙarfe na titanium da ƙarfe na nickel-aluminum. Amma foda na ƙarfe mai bugawa na 3D ba wai kawai dole ne ya sami kyakkyawan filastik ba, har ma ya cika buƙatun girman ƙananan ƙwayoyin, rarraba girman ƙananan ƙwayoyin, babban sphericity, kyakkyawan ruwa da yawan sako-sako. Saboda buƙatun aikace-aikace daban-daban da tsarin ƙera kayayyaki na gaba, hanyoyin shirya foda na ƙarfe suma sun bambanta. Dangane da tsarin shiryawa, ya haɗa da hanyar sunadarai ta zahiri da hanyar injiniya. A cikin masana'antar ƙarfe na foda, ana amfani da hanyoyi kamar electrolysis, raguwa da atomization sosai. Duk da haka, ya kamata a lura cewa dukkan hanyoyin suna da iyakokinsu, ba su dace da shirya foda na alloy ba. A halin yanzu, foda na ƙarfe don ƙera ƙari galibi yana cikin ƙarfe na titanium, ƙarfe mai zafi, ƙarfe na cobalt-chromium, ƙarfe mai ƙarfi da ƙarfe mai mutuwa. Domin biyan buƙatun kayan aiki da sarrafawa na ƙera ƙari, foda na ƙarfe dole ne ya kasance yana da halayen ƙarancin iskar oxygen da nitrogen, kyakkyawan matakin ƙwallo, kewayon rarrabawar ƙananan barbashi da kuma yawan sako-sako. A halin yanzu, manyan hanyoyin shirya foda na ƙarfe don ƙera ƙari sune electrode mai juyawa na plasma (PREP), atomization na plasma (PA), gas atomization (GA) da plasma spheroidization (PS), duk ana iya amfani da su don shirya foda na ƙarfe mai zagaye ko kusa da ƙwallo
