Ngophuhliso lwenzululwazi kunye nobuchwepheshe kunye nokukhuthazwa kokusetyenziswa kwemfuno, ukusetyenziswa kweprototyping ekhawulezayo ukwenza ngokuthe ngqo iinxalenye ezisebenzayo zentsimbi iye yaba lolona khokelo luphambili lophuhliso lweprototyping ekhawulezayo. Okwangoku, isinyithi esiphambiliUshicilelo lwe-3D iinkqubo ezinokuthi zisetyenziswe ukwenza ngokuthe ngqo iinxalenye ezisebenzayo zentsimbi ziquka: I-Laser Sintering ekhethiweyo(SLS) iteknoloji, Ngqo Metal Laser Sintering(DMLS)itekhnoloji, Ukunyibilika kweLaser ekhethiweyo (SLM)iteknoloji, Laser Ubunjineli Net Shaping(LENS)iteknoloji kunye ne-Electron Beam Selective Melting(EBSM)iteknoloji, njl.
Ukukhetha i-laser sintering(SLS)
Ukukhetha i-laser sintering, njengoko negama lisitsho, yamkela inkqubo yolwelo ye-sintering metallurgical mechanism. Ngexesha lenkqubo yokuqulunqa, i-powder material iyancibilika ngokuyinxenye, kwaye amasuntswana omgubo agcina ii-cores zesigaba esiqinileyo, ezithi ziphinde zihlengahlengiswe ngamasuntswana esigaba esiqinileyo kunye nokuqina kwesigaba solwelo. Ukudibanisa kufeza ukuxinana komgubo.
Itekhnoloji ye-SLSumgaqo kunye neempawu:
Isixhobo esipheleleyo senkqubo siqulunqwe ngepowder cylinder kunye ne-cylinder yokwenza. I-powder cylinder piston (i-powder feeding piston) iyenyuka, kwaye i-powder ebeka i-roller ngokulinganayo isasaza umgubo kwi-cylinder piston (ipiston yokusebenza). Ikhompyuter ilawula i-trajectory ye-scan ye-two-dimensional ye-laser beam ngokwemodeli yesilayi yeprototype, kwaye ngokukhethayo i-sinters into eyomeleleyo yomgubo ukwenza umaleko wenxalenye. Emva kokugqiba umaleko, i-piston esebenzayo ithotywa umaleko omnye obunzima, inkqubo yokubeka umgubo ibekwe ngomgubo omtsha, kwaye i-laser beam ilawulwa ukuskena kunye nokutshiza umaleko omtsha. Lo mjikelo uqhubeka kwaye uqhube, umaleko ngokomaleko, de abe ngamalungu amathathu-dimensional enziwe.
