I-Metal 3D yobuchwepheshe bokuphrinta impushanaukubumba inqubo isifinyezo, ukwaziswa okushisayo, njengoba ingxenye ebaluleke kakhulu izingxenye zensimbi 3D umkhakha wokunyathelisa chain, futhi inani elikhulu kunawo wonke. Engqungqutheleni ye-World 3D yemboni yokunyathelisa ka-2013, ochwepheshe abahamba phambili embonini yokunyathelisa ye-3D World banikeze incazelo ecacile ye-3d ephrintiwe yensimbi powder, okungukuthi, ubukhulu obungaphansi kwe-1mm yezinhlayiya zensimbi. Kuhlanganisa impushana yensimbi eyodwa, i-alloy powder kanye ne-refractory compound powder enempahla yensimbi. Njengamanje, izinto ze-3D zensimbi zokuphrinta zifaka ingxubevange ye-cobalt-chromium, insimbi engagqwali, insimbi yezimboni, ingxubevange yethusi, ingxubevange ye-titanium ne-nickel-aluminium alloy. Kodwa impushana yensimbi ephrintiwe ye-3D akumele ibe ne-plasticity enhle kuphela, kodwa futhi ihlangabezane nezidingo zosayizi wezinhlayiyana ezincane, ukusatshalaliswa kosayizi wezinhlayiyana ezincane, ukujula okuphezulu, uketshezi oluhle kanye nokuminyana okuphezulu okuxekethile. Ngenxa yezidingo ezahlukene zesicelo kanye nenqubo yokubumba elandelayo, izindlela zokulungiselela ze-metal powder nazo zihlukile. Ngokusho kwenqubo yokulungiselela, ikakhulukazi ihlanganisa indlela ye-chemistry yomzimba kanye nendlela yemishini. Embonini ye-Powder metallurgy, izindlela ezifana ne-electrolysis, ukunciphisa kanye ne-atomization zisetshenziswa kabanzi. Kodwa-ke, kufanele kuqashelwe ukuthi zombili izindlela zinemikhawulo yazo, azifanelekile ukulungiswa kwe-alloy powder. Njengamanje, i-metal powder yokukhiqiza okungeziwe igxile kakhulu ku-titanium alloy, izinga lokushisa eliphezulu ingxubevange, ingxubevange ye-cobalt-chromium, insimbi enamandla amakhulu kanye nensimbi yokufa. Ukuze kuhlangatshezwane nezidingo zemishini yokukhiqiza okungeziwe kanye nenqubo, impushana yensimbi kufanele ibe nezici zokuqukethwe okuphansi kwe-oksijeni ne-nitrogen, i-spherical degree enhle, ububanzi bokusabalalisa usayizi wezinhlayiyana ezincane kanye nokuminyana okuphezulu okuxekethile. Njengamanje, izindlela eziyinhloko zokulungiselela izimpushana zensimbi zokukhiqiza okungeziwe yi-electrode ejikelezayo ye-plasma (PREP) , i-plasma atomization (PA) , i-atomization yegesi (GA) kanye ne-plasma spheroidization (PS) , zonke zingasetshenziswa ukulungisa i-spherical noma eduze. -i-spherical metal powde
