I-Metal 3D yoshicilelo lwetekhnoloji umguboinkqubo yokubumba isishwankathelo, ulwazi eshushu, njengeyona nxalenye ibalulekileyo yamacandelo metal 3D umxokelelwane ishishini loshicilelo, kwakhona ixabiso elikhulu. Kwi-World 3D inkomfa yoshicilelo yoshicilelo lwe-2013, iingcali ezikhokelayo kwi-World 3D imboni yoshicilelo yanika inkcazo ecacileyo ye-3d eprintiweyo ye-metal powder, oko kukuthi, ubukhulu obungaphantsi kwe-1mm yeengqungquthela zetsimbi. Ibandakanya umgubo wentsimbi enye, umgubo wealloyi kunye nomgubo owenziwe ngerefractory onepropathi yentsimbi. Okwangoku, i-3D yoshicilelo lwezixhobo zentsimbi yomgubo ibandakanya i-cobalt-chromium ingxubevange, insimbi engenasici, intsimbi yoshishino, ialloy yobhedu, i-titanium alloy kunye ne-nickel-aluminium alloy. Kodwa umgubo wesinyithi oprintiweyo we-3D akufuneki ube neplastiki elungileyo kuphela, kodwa ukwahlangabezana neemfuno zobungakanani besuntswana elicolekileyo, ukuhanjiswa kobungakanani besuntswana elimxinwa, ubunzulu obuphezulu, ubumanzi obulungileyo kunye noxinaniso olukhulu. Ngenxa yeemfuno ezahlukeneyo zesicelo kunye nenkqubo yokubumba elandelayo, iindlela zokulungiselela umgubo wesinyithi nazo zihluke. Ngokwenkqubo yokulungiselela, ikakhulu ibandakanya indlela yekhemistri yomzimba kunye nendlela yomatshini. Kwishishini leMetallurgy yePowder, iindlela ezinje nge-electrolysis, ukunciphisa kunye ne-atomization zisetyenziswa kakhulu. Nangona kunjalo, kufuneka kuqatshelwe ukuba zombini iindlela zinemida yazo, ayifanelekanga ukulungiswa kwe-alloy powder. Okwangoku, umgubo wesinyithi wokwenza okongeziweyo ugxile kakhulu kwi-titanium alloy, i-alloy yobushushu obuphezulu, ingxubevange ye-cobalt-chromium, intsimbi ephezulu kunye nentsimbi yokufa. Ukuze kuhlangatyezwane neemfuno zezixhobo zokuvelisa ezongezelelweyo kunye nenkqubo, umgubo wesinyithi kufuneka ube neempawu zomxholo ophantsi we-oksijini kunye ne-nitrogen, idigri elungileyo ye-spherical, uluhlu oluncinci lokusabalalisa ubungakanani be-particle kunye nokuxinana okuphezulu. Okwangoku, iindlela eziphambili zokulungiselela i-powders yensimbi yokwenziwa kokongeza i-electrode ejikelezayo ye-plasma (PREP) , i-plasma atomization (PA) , i-atomization yegesi (GA) kunye ne-plasma spheroidization (PS) , zonke zingasetyenziselwa ukulungiselela i-spherical okanye kufuphi. -powde yentsimbi engqukuva
