Laser YatoranijweMelting (SLM), bizwi kandi nka laser fusion welding, ni tekinoroji itanga inyongera yinganda zikoreshwa mubyuma bifashisha urumuri rwinshi rwa laser kugirango rumurikire kandi rushonga burundu ifu yicyuma kugirango ibe ishusho ya 3D, kandi akenshi ifatwa nkigice cya tekinoroji ya Selective Laser Sintering (SLS).
Ibyuma-bisaMaterial
Ibikoresho by'icyuma bikoreshwa muri SLS ni uruvange rw'ibikoresho bivangwa kandi bishonga bike cyangwa ibyuma bya molekile, mugihe cyo gutunganya ibikoresho byo hasi byo gushonga bishonga ariko ifu yicyuma kinini ntigikora.Ibikoresho bishongeshejwe bikoreshwa muguhuza, bityo ibinini birakomeye kandi bifite imiterere yubukanishi, kandi bigomba gusubirwamo ubushyuhe bwinshi mbere yuko bikoreshwa.
Byoseinzira yaSLMprintingitangirana no gukata amakuru ya 3D CAD, ihindura amakuru ya 3D mubice byinshi bya 2D, mubisanzwe hagati ya 20m na 100pm mubugari.3D CAD data isanzwe ikorwa nka dosiye ya STL, nayo ikoreshwa mubindi bikoresho bya tekinoroji ya 3D.Amakuru ya CAD yinjizwa muri software ikata kandi ibipimo bitandukanye byumutungo byashyizweho, kimwe nibintu bimwe na bimwe byo kugenzura gucapa.SLM itangira icapiro mugucapisha urwego ruto, rumwe kuri substrate, hanyuma ikanyuzwa muri Z-axis kugirango icapishe imiterere ya 3D.
Igikorwa cyose cyo gucapa gikorerwa mubintu bifunze byuzuye gaze ya inert, argon cyangwa azote, kugirango ogisijeni igere kuri 0.05%.Uburyo bwaSLM mugucunga vibrateri kugirango ugere kuri lazeri yumuriro wifu, gushyushya ibyuma kugeza bishonge burundu, buri rwego rwimirimo yumurimo wa irrasiyo rumanuka, uburyo bwa tiling bwongeye gukorwa, hanyuma laser ikarangiza irrasiyo yikurikiranya, bityo ko igipande gishya cya poro cyashongeshejwe kandi kigahuzwa hamwe nicyiciro kibanza, gisubiramo uruziga kugirango rwuzuze 3D geometrie.Umwanya ukoreramo wuzuyemo gaze ya inert kugirango wirinde okiside yifu yicyuma kandi bamwe bafite uburyo bwo kuzenguruka ikirere kugirango bakureho urumuri muri lazeri.
SLM ibice byacapwe birangwa nubucucike bwinshi nimbaraga nyinshi.Uburyo bwa SLM bwo gucapa ni imbaraga nyinshi cyane, kandi buri gice cyifu yicyuma kigomba gushyuha kugeza aho icyuma gishonga.Ubushyuhe bwo hejuru butera impungenge zisigaye imbere muri SLM ibikoresho byanyuma byanditse, bishobora kugira ingaruka kumiterere yigice.
Icapa ryicyuma cya JS Additive ritangwa nabakora ibicuruzwa bizwi cyane mu gihugu, kandi serivisi zayo zo gucapa ibyuma bya 3D zagutse kugera ku masoko yo hanze ku isi, aho ubwiza n’ibitangwa bizwi neza n’abakiriya bo mu mahanga, cyane cyane mu Burayi, Amerika, Ubuyapani, Ubutaliyani, Espanye na Aziya y'Amajyepfo.Serivisi zo gucapa ibyuma bya 3D zikoreshwa cyane cyane mu gufasha inganda gakondo guhindura uburyo zitanga umusaruro, kuzigama igihe nigiciro cyibicuruzwa ubwabyo, cyane cyane mubihe bibi by’icyorezo.
