Me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana a me ka hoʻolaha ʻana i ka noi noi, ʻo ka hoʻohana ʻana i ka prototyping wikiwiki e hana pololei i nā ʻāpana hana metala ua lilo i alakaʻi hoʻomohala nui o ka prototyping wikiwiki.I kēia manawa, ka metala nuiPaʻi 3D ʻO nā kaʻina hana i hiki ke hoʻohana ʻia no ka hana pololei ʻana i nā ʻāpana hana metala: Selective Laser Sintering(SLS) ʻenehana, Hoʻopaʻa ʻia ʻo Direct Metal Laser Sintering(DMLS)ʻenehana, Selective Laser Melting (SLM)ʻenehana, Laser Engineered Net Shaping(LENS)ʻenehana a me ka Electron Beam Selective Melting(EBSM)ʻenehana, etc.
ʻO ka hoʻopaʻa ʻana i ka laser koho(SLS)
ʻO ka sintering laser koho, e like me ka inoa e hōʻike nei, e hoʻohana i kahi mīkini hana hoʻoheheʻe wai.I ka wā o ke kaʻina hana, ua hoʻoheheʻe ʻia ka mea pauda, a mālama nā ʻāpana pauka i ko lākou mau cores paʻa, a laila hoʻonohonoho hou ʻia ma o nā ʻāpana paʻa hope a me ka paʻa wai.Loaʻa i ka hoʻopaʻa ʻana i ka pauka densification.
ʻenehana SLSkumu a me nā hiʻohiʻona:
Hoʻokumu ʻia ka mīkini hana holoʻokoʻa me ka pauka pauka a me ka cylinder hana.Ke piʻi aʻe nei ka piston hoʻoheheʻe pauda (piston hānai pauda), a hoʻolaha like ka huila hoʻomoe i ka pauda ma luna o ka piston hana (piston hana).Mālama ka lolouila i ka ʻaoʻao scanning ʻelua ʻāpana o ka kukuna laser e like me ke kumu hoʻohālike ʻāpana o ka prototype, a me ke koho ʻana i ka mea pauka paʻa e hana i kahi papa o ka ʻāpana.Ma hope o ka pau ʻana o kahi papa, hoʻohaʻahaʻa ʻia ka piston hana i hoʻokahi papa mānoanoa, waiho ʻia ka ʻōnaehana waiho ʻana i ka pauka me ka pauka hou, a mālama ʻia ka kukuna laser e nānā a hoʻopaʻa i ka papa hou.Ke hoʻomau nei kēia pōʻaiapuni, papa ma ka papa, a hiki i ka hana ʻana o nā ʻāpana ʻekolu.
