Metala ʻenehana paʻi 3D paudaʻO ka hōʻuluʻulu kaʻina hana hoʻoheheʻe, ʻike wela, ʻo ia ka mea nui o nā ʻāpana metala 3D paʻi ʻoihana kaulahao, ʻo ia ka waiwai nui loa. Ma ka World 3D printing industry conference 2013, alakaʻi i ka poʻe akamai i ka World 3D paʻi ʻoihana i hāʻawi i kahi wehewehe maopopo o 3d paʻi metala pauka, ʻo ia hoʻi, ka nui o ka liʻiliʻi ma mua o 1mm o nā mea metala. Loaʻa iā ia ka pauka metala hoʻokahi, ka pauka alloy a me ka pauka hui refractory me ka waiwai metala. I kēia manawa, ʻo nā mea paʻi metala paʻi 3D e komo pū me ka cobalt-chromium alloy, ke kila kila, ke kila ʻoihana, ke keleawe keleawe, ka titanium alloy a me ka nickel-aluminum alloy. Akā ʻo ka pauka metala paʻi 3D ʻaʻole pono e loaʻa i ka plasticity maikaʻi wale nō, akā e hoʻokō pū i nā koi o ka nui o ka ʻāpana liʻiliʻi, ka hāʻawi ʻana i ka nui o ka ʻāpana, ka sphericity kiʻekiʻe, ka wai maikaʻi a me ke kiʻekiʻe kiʻekiʻe. Ma muli o nā koi like ʻole o ka noi a me ke kaʻina hana hoʻoheheʻe ʻana, ʻokoʻa nā ʻano hoʻomākaukau o ka pauka metala. Wahi a ke kaʻina hana hoʻomākaukau, ʻo ia ka mea nui e pili ana i ke ʻano kemika kino a me ke ʻano mechanical. I ka ʻoihana Metallurgy Powder, hoʻohana nui ʻia nā ʻano e like me ka electrolysis, hōʻemi a me ka atomization. Eia naʻe, pono e hoʻomaopopo ʻia he mau palena ko nā ʻano ʻelua, ʻaʻole kūpono no ka hoʻomākaukau ʻana i ka pauka alloy. I kēia manawa, ʻoi aku ka nui o ka pauka metala no ka hana hoʻohui ʻana i ka titanium alloy, kiʻekiʻe kiʻekiʻe wela alloy, cobalt-chromium alloy, kiʻekiʻe ikaika kila a me ke kila make. I mea e hoʻokō ai i nā koi o nā mea hana hoʻohui a me nā kaʻina hana, pono e loaʻa i ka pauka metala nā hiʻohiʻona o ka haʻahaʻa haʻahaʻa o ka oxygen a me ka nitrogen, maikaʻi spherical degere, haiki liʻiliʻi ka nui o ka hāʻawi ʻana a me ke kiʻekiʻe haʻahaʻa. I kēia manawa, ʻo nā ala nui o ka hoʻomākaukau ʻana i nā pauka metala no ka hana hoʻohui ʻana he plasma rotating electrode (PREP), plasma atomization (PA), gas atomization (GA) a me plasma spheroidization (PS), hiki ke hoʻohana ʻia ia mau mea āpau e hoʻomākaukau ai i ka spherical a kokoke paha. -powde metala poʻe
