Upfu hwetekinoroji yekudhinda yesimbi ye3DMuchidimbu, ruzivo rwakanyanya, sechikamu chakakosha chezvikamu zvesimbi cheni yeindasitiri yekudhinda ye3D, ndicho chinhu chinonyanya kukosha. Pamusangano weindasitiri yekudhinda ye3D weWorld 3D wa2013, nyanzvi dzinotungamira muindasitiri yekudhinda yeWorld 3D dzakapa tsananguro yakajeka yeupfu hwesimbi hwakadhindwa hwe3D, kureva kuti, saizi isingasviki 1mm yezvidimbu zvesimbi. Inosanganisira upfu hwesimbi imwe chete, upfu hwealloy uye humwe upfu hwecompound husina kusimba hune hunhu hwesimbi. Parizvino, zvinhu zveupfu hwesimbi zvekudhinda zve3D zvinosanganisira cobalt-chromium alloy, simbi isingasvibi, simbi yeindasitiri, bronze alloy, titanium alloy uye nickel-aluminium alloy. Asi upfu hwesimbi hwakadhindwa hwe3D hahufanirwe kungova nepurasitiki yakanaka chete, asiwo hunosangana nezvinodiwa zvehukuru hwezvidimbu zvidiki, kugoverwa kwehukuru hwezvidimbu zvidiki, sphericity yakakwira, fluidity yakanaka uye high loose density. Nekuda kwezvinodiwa zvakasiyana zvekushandisa uye maitiro anotevera ekuumba, nzira dzekugadzirira upfu hwesimbi dzakasiyanawo. Zvichienderana nemaitiro ekugadzirira, zvinonyanya kusanganisira nzira yemakemikari emuviri uye nzira yemakanika. Muindasitiri yesimbi yePowder, nzira dzakadai se electrolysis, reduction uye atomization dzinoshandiswa zvakanyanya. Zvisinei, zvinofanira kucherechedzwa kuti nzira dzese dziri mbiri dzine miganhu yadzo, hadzina kukodzera kugadzirwa kwehupfu hwe alloy. Parizvino, hupfu hwesimbi hwekugadzira zvinhu zvinowedzera hunonyanya kusanganiswa ne titanium alloy, high temperature alloy, cobalt-chromium alloy, high strength steel uye die steel. Kuti zvizadzise zvinodiwa zvemidziyo yekugadzira zvinhu zvinowedzera uye maitiro, hupfu hwesimbi hunofanirwa kunge huine hunhu hwe oxygen ne nitrogen shoma, denderedzwa rakanaka, diki particle size distribution range uye high loose density. Parizvino, nzira huru dzekugadzirira hupfu hwesimbi hwekugadzira zvinhu zvinowedzera ndi plasma rotating electrode (PREP), plasma atomization (PA), gas atomization (GA) uye plasma spheroidization (PS), dzese dzinogona kushandiswa kugadzira hupfu hwesimbi hwakaita sedenderedzwa kana kuti hwakaita sedenderedzwa.
