Ukuncibilika kwe-Laser okukhethiwe (I-SLM) , eyaziwa nangokuthi i-laser fusion welding, iwubuchwepheshe obuthembisayo bokukhiqiza okuyisengezo bensimbi obusebenzisa ukukhanya kwelaser yamandla aphezulu ukuze kucwebezeliswe futhi kuncibilike ngokuphelele izimpushana zensimbi ukuze zakhe izimo ze-3D.
Impahla yensimbi esetshenziswa ku-SLM iyingxube yensimbi ephekiwe nephansi encibilika noma i-molecular material, ngesikhathi sokucubungula indawo encibilikayo ephansi iyancibilika kodwa indawo ephezulu yokuncibilika yensimbi ayishintshi.Izinto ezincibilikisiwe zisetshenziselwa ukubopha, ngakho izinto eziqinile zinezimbotshana futhi zinezimo ezingezinhle zemishini, futhi kufanele zincibilikiswe emazingeni okushisa aphezulu ngaphambi kokuba zisetshenziswe.
Yonke inqubo yeUkuphrinta kwe-SLMkuqala ngokusika idatha ye-3D CAD, ukuguqula idatha ye-3D ibe inombolo yezendlalelo zedatha ye-2D, ngokuvamile phakathi kuka-20m no-100pm ngogqinsi.Idatha ye-3DCAD ijwayele ukufomethwa njengamafayela e-STL, aphinde asetshenziswe ngokujwayelekile kobunye ubuchwepheshe bokuphrinta be-3D obugqinsi.Idatha ye-CAD ingeniswa ku-software yokusika futhi imingcele yendawo ehlukahlukene isethiwe, kanye neminye imingcele yokulawula yokuphrinta.I-SLM iqala inqubo yokuphrinta ngokuphrinta ungqimba oluncane olufana noluncane ku-substrate, bese luhanjiswa ku-axis engu-Z ukuze kuphrintwe umumo we-3D.
Yonke inqubo yokunyathelisa yenziwa esitsheni esivaliwe esigcwele igesi ye-inert, i-argon noma i-nitrogen, ukunciphisa okuqukethwe kwe-oxygen ku-0.05%.I-SLM isebenza ngokulawula isidlidlizi ukuze kuzuzwe i-laser irradiation ye-thayela powder, ukushisisa insimbi ize incibilike ngokuphelele, izinga ngalinye letafula lomsebenzi we-irradiation liyehla, indlela yokufaka amathayela iyenziwa futhi, bese i-laser iqeda ukushiswa kwesendlalelo esilandelayo. , ukuze ungqimba olusha lwempushana luncibilike futhi luhlanganiswe kanye nongqimba lwangaphambilini, kuphinda umjikelezo ukuze kuqedelwe ijometri ye-3D.Indawo yokusebenza ivamise ukugcwaliswa ngegesi engasebenzi ukuze kugwenywe ukugcotshwa kwempushana yensimbi kanti abanye banezinhlelo zokuzungeza komoya ukuze kuqedwe izinhlansi ku-laser.
Izingxenye eziphrintiwe ze-SLM zibonakala ngokuminyana okuphezulu namandla aphezulu.Inqubo yokunyathelisa ye-SLM inamandla amakhulu kakhulu, futhi ungqimba ngalunye lwe-powder yensimbi kufanele lushiswe endaweni yokuncibilika kwensimbi.Ukushisa okuphezulu kubangela ukucindezeleka okusele ngaphakathi kwezinto eziphrintiwe zokugcina ze-SLM, ezingathinta izakhiwo zemishini zengxenye.
I-JSAAd 3D Amaphrinta ensimbi ahlinzekwa ngabakhiqizi basekhaya abaziwayo, futhi yayoIzinsizakalo zokuphrinta zensimbi ze-3Dziye zanda ezimakethe zaphesheya kwezilwandle emhlabeni jikelele, lapho izinga nezikhathi zokulethwa ziqashelwa kahle ngamakhasimende aphesheya kwezilwandle, ikakhulukazi eYurophu, eMelika, eJapan, e-Italy, eSpain naseNingizimu East Asia.Izinsizakalo zokuphrinta zensimbi ze-3D zisetshenziswa kakhulu ukusiza amabhizinisi endabuko ukuthi aguqule indlela akhiqiza ngayo, ukonga isikhathi kanye nezindleko zomkhiqizo ngokwawo, ikakhulukazi endaweni yamanje enokhahlo yalolu bhubhane.
Uma ufuna ukwazi ulwazi olwengeziwe futhi udinga ukwenza imodeli yokuphrinta ye-3d, sicela uxhumaneI-JSADD 3D Manufacturerzikhathi zonke.
