Ukunyibilika kweLaser ekhethiweyo (I-SLM), ekwabizwa ngokuba yi-laser fusion welding, iteknoloji yokuvelisa ezongezelelweyo ezithembisayo zesinyithi ezisebenzisa ukukhanya kwelaser yamandla aphezulu ukuntywila kunye nokunyibilikisa ngokupheleleyo umgubo wesinyithi ukwenza iimilo ze-3D.
Izinto zetsimbi ezisetyenziswe kwi-SLM ngumxube wentsimbi ephathwayo kunye nesezantsi enyibilikayo okanye i-molecular material, ngexesha lokucutshungulwa kwezinto ezisezantsi zokunyibilika 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.
Yonke inkqubo yeUshicilelo lwe-SLMiqala 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-3DCAD 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%.I-SLM isebenza ngokulawula i-vibrator ukufezekisa i-laser irradiation yomgubo wokuthayela, ukufudumeza isinyithi de inyibilike ngokupheleleyo, inqanaba ngalinye letafile yomsebenzi we-irradiation yehla, indlela yokufaka ithayile iphinda iqhutywe, kwaye emva koko i-laser igqibezela iradiation yomaleko olandelayo. , ukwenzela ukuba uluhlu olutsha lwepowder luncibilike kwaye luhlanganiswe kunye noluhlu lwangaphambili, ukuphinda umjikelezo 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 ziphawulwa 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.
JSAAd 3D abashicileli bentsimbi babonelelwa ngabavelisi abaziwayo basekhaya, kunye neIinkonzo zoshicilelo lwesinyithi ze-3Dziye zanda kwiimarike zaphesheya kwihlabathi liphela, apho umgangatho kunye namaxesha okuhanjiswa abonwa kakuhle ngabathengi baphesheya, ngakumbi eYurophu, eMelika, eJapan, eItali, eSpain nakumazantsi mpuma eAsia.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.
Ukuba ufuna ukwazi ulwazi oluninzi kwaye ufuna ukwenza imodeli yoshicilelo ye-3d, nceda uqhagamshelaneJSADD 3D Manufacturerngalo lonke ixesha.
