ILaser ekhethiweyoMelting (SLM), ekwabizwa ngokuba yi-laser fusion welding, iteknoloji yokuvelisa ezongezelelweyo ezithembisayo zesinyithi ezisebenzisa ukukhanya kwelaser yamandla aphezulu ukuze kukhanye kwaye kunyibilike ngokupheleleyo umgubo wesinyithi ukwenza iimilo ze-3D, kwaye ihlala ithathwa njengeseti esezantsi yetekhnoloji ye-Selective Laser Sintering (SLS).
Isinyithi -njengeMizixhobo
Izinto zetsimbi ezisetyenziswa kwi-SLS ngumxube wentsimbi ephathwayo kunye nesezantsi yokunyibilika kwentsimbi okanye izinto zemolekyuli, ngexesha lokusetyenzwa kwezinto ezincibilikayo ezisezantsi ziyanyibilika kodwa indawo ephezulu yokunyibilika yentsimbi ayifuni.Isixhobo esinyibilikisiweyo sisetyenziselwa ukudibanisa, ngoko ke izinto eziqinileyo zibubuvuvu kwaye zineempawu ezimbi zomatshini, kwaye kufuneka ziphinde zinyibilike kumaqondo aphezulu ngaphambi kokuba zisetyenziswe.
Yonkeinkqubo yeI-SLMpukurentaiqala ngokusika idatha ye-3D ye-CAD, ukuguqula idatha ye-3D kwinani ledatha ye-2D yedatha, ngokuqhelekileyo phakathi kwe-20m kunye ne-100pm ngobukhulu.Idatha ye-3D CAD idla ngokufomathwa njengeefayile ze-STL, eziqhele ukusetyenziswa kobunye ubuchwephesha boshicilelo be-3D.Idatha ye-CAD ingeniswa kwisoftware yokusika kwaye iiparamitha ezahlukeneyo zepropathi zisetiwe, kunye nezinye iiparamitha zolawulo lokushicilela.I-SLM iqalisa inkqubo yoshicilelo ngokushicilela umaleko obhityileyo, ofanayo kwi-substrate, ethi emva koko ihanjiswe nge-Z-axis ukuprinta imilo ye-3D.
Yonke inkqubo yokushicilela iqhutyelwa kwisitya esivaliweyo esigcwele igesi ye-inert, i-argon okanye i-nitrogen, ukunciphisa umxholo we-oxygen kwi-0.05%.Iindlela zeI-SLM ngokulawula i-vibrator ukufezekisa i-laser irradiation ye-tileng powder, ukufudumeza isinyithi de inyibilike ngokupheleleyo, inqanaba ngalinye letafile yomsebenzi we-irradiation yehla, i-tileing mechanism iqhutywe kwakhona, kwaye emva koko i-laser igqibezela ukulayishwa koluhlu olulandelayo, ngoko ke. ukuba umaleko omtsha we powder uyanyibilika kwaye udibaniswe kunye nomgangatho wangaphambili, uphinda umjikelo ukugqiba ijometri ye-3D.Indawo yokusebenza idla ngokuzaliswa ngerhasi engasebenziyo ukuthintela i-oxidation yomgubo wesinyithi kwaye abanye baneenkqubo zokujikeleza komoya ukuphelisa iintlantsi kwi-laser.
Amacandelo ashicilelweyo e-SLM abonakaliswe ngoxinzelelo oluphezulu kunye namandla aphezulu.Inkqubo yokushicilela ye-SLM inamandla kakhulu, kwaye uluhlu ngalunye lwe-powder yensimbi kufuneka lutshiswe kwindawo yokunyibilika kwesinyithi.Ubushushu obuphezulu bubangela uxinzelelo olushiyekileyo ngaphakathi kwe-SLM yokugqibela eprintiweyo, enokuchaphazela iipropathi zomatshini zenxalenye.
Iiprinta zentsimbi ze-JS Additive zibonelelwa ngabavelisi abaziwayo basekhaya, kwaye iinkonzo zayo zoshicilelo zesinyithi ze-3D ziye zanda kwiimarike zaphesheya emhlabeni jikelele, apho umgangatho kunye namaxesha okuhanjiswa abonwa kakuhle ngabathengi baphesheya, ngakumbi eYurophu, eMelika, eJapan, eItali, eSpain. kunye noMzantsi Mpuma Asia.Iinkonzo zoshicilelo lwesinyithi ze-3D zisetyenziselwa kakhulu ukunceda amashishini emveli atshintshe indlela avelisa ngayo, ukonga ixesha kunye neendleko zemveliso ngokwayo, ngakumbi kwimekobume erhabaxa yangoku yobhubhani.
