Sarudza LaserMkusimudza (SLM), inozivikanwawo selaser fusion welding, inovimbisa zvikuru yekuwedzera yekugadzira tekinoroji yesimbi inoshandisa yakakwira simba laser mwenje kuburitsa uye kunyungudutsa zvachose simbi hupfu kuita 3D zvimiro, uye inowanzoonekwa sechikamu cheSelective Laser Sintering (SLS) tekinoroji.
Metal-yakafananaMzvinhu
Iyo simbi inoshandiswa muSLS musanganiswa weyakagadziriswa uye yakaderera kunyungudika simbi kana mamorekuru zvinhu, panguva yekugadzira iyo yakaderera nzvimbo yekunyungudika inonyungudika asi iyo yakakwira yekunyungudika simbi poda haidaro.Iyo yakanyungudutswa inoshandiswa pakubatanidza, saka iyo yakaoma ine porous uye ine urombo mechanical properties, uye inofanira kunyungudutswa pakupisa kwepamusoro isati yashandiswa.
The wholeprocess yeSLMprintinginotanga nekucheka 3D CAD data, kushandura iyo 3D data kuita nhamba ye2D data layer, kazhinji pakati pe20m ne100pm mukukora.3D CAD data inowanzo kurongeka seSTL mafaera, ayo anowanzo shandiswa mune mamwe akaturikidzana 3D kudhinda matekinoroji.Iyo data yeCAD inounzwa kunze kweiyo slicing software uye akasiyana ezvivakwa paramita akaiswa, pamwe nemamwe maparamita ekudzora ekudhinda.SLM inotanga kudhinda nekudhinda chidimbu chakatetepa, chakafanana pane substrate, iyo inozofambiswa kuburikidza neZ-axis kudhinda chimiro che3D.
Kudhinda kwese kunoitwa mumudziyo wakavharwa wakazadzwa neinert gasi, argon kana nitrogen, kuderedza okisijeni kusvika ku0.05%.Nzira dzeSLM nekudzora vibrator kuti iwane laser irradiation yetiling poda, kupisa simbi kusvika yanyunguduka, imwe neimwe nhanho yetafura yebasa reirradiation inodzika pasi, nzira yekuisa matairi inoitwa zvakare, uyezve laser inopedzisa kuvhenekera kweiyo inotevera layer, saka. kuti hutsva hutsva hwehupfu hunonyungudutswa uye hunobatanidzwa pamwe chete nechekare, kudzokorora kutenderera kupedzisa 3D geometry.Nzvimbo yekushandira inowanzozadzwa neinert gasi kudzivirira oxidation yehupfu hwesimbi uye vamwe vane mweya wekutenderera masisitimu ekubvisa sparks kubva kune laser.
SLM yakadhindwa zvikamu zvinoratidzwa nehupamhi hwepamusoro uye simba rakawanda.Kudhinda kweSLM kwakanyanyisa-simba, uye imwe neimwe yehupfu hwesimbi inofanira kupiswa kusvika pakunyunguduka kwesimbi.Iyo tembiricha yepamusoro inokonzeresa kushushikana mukati me SLM yekupedzisira yakadhindwa zvinhu, izvo zvinogona kukanganisa ma mechanika echikamu.
JS Additive's simbi inodhinda inopihwa nevanozivikanwa vagadziri vepamba, uye yayo 3D simbi yekudhinda masevhisi akawedzera kusvika kumisika yekunze pasirese, uko mhando uye nguva dzekutumira dzinonyatso zivikanwa nevatengi vekunze, kunyanya muEurope, America, Japan, Italy, Spain. uye South East Asia.3D simbi yekudhinda masevhisi anonyanya kushandiswa kubatsira mabhizinesi echinyakare kushandura nzira yaanogadzira, kuchengetedza nguva uye mutengo wechigadzirwa chacho, kunyanya munzvimbo yazvino yakaoma yedenda.
