Sarudza Laser kunyunguduka (SLM), inozivikanwawo selaser fusion welding, inovimbisa zvikuru yekuwedzera yekugadzira tekinoroji yesimbi inoshandisa yakakwira simba laser mwenje kuburitsa uye kunyungudutsa zvachose simbi hupfu kugadzira 3D zvimiro.
Iyo simbi inoshandiswa muSLM musanganiswa weyakagadziriswa uye yakaderera kunyungudika simbi kana mamorekuru zvinhu, panguva yekugadzira iyo yakaderera inonyungudika zvinhu zvinonyunguduka asi iyo yakakwira yekunyungudika simbi poda haina.Iyo yakanyungudutswa inoshandiswa pakubatanidza, saka iyo yakaoma ine porous uye ine urombo mechanical properties, uye inofanira kunyungudutswa pakupisa kwepamusoro isati yashandiswa.
Nzira yose yeSLM kudhindainotanga nekucheka 3D CAD data, kushandura iyo 3D data kuita nhamba ye2D data layer, kazhinji pakati pe20m ne100pm mukukora.3DCAD data inowanzo kurongeka seSTL mafaera, ayo anowanzo shandiswa mune mamwe akaturikidzana 3D tekinoroji ekudhinda.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%.SLM inoshanda nekudzora vibrator kuti iwane laser irradiation yetiling poda, ichidziya simbi kusvika yanyunguduka, imwe neimwe nhanho yetafura yebasa rekuvhenekesa inodzika pasi, nzira yekuisa matairi inoitwa zvakare, uyezve laser inopedzisa kuvhenekera kweiyo inotevera layer. , kuitira kuti hutsva hutsva hwehupfu hunyunguduke uye hunobatanidzwa pamwe chete nechekare, kudzokorora kutenderera kupedzisa 3D geometry.Nzvimbo yekushandira inowanzozadzwa neinert gasi kudzivirira oxidation yehupfu hwesimbi uye vamwe vane mhepo yekutenderera masisitimu ekubvisa spark kubva kune laser.
SLM yakadhindwa zvikamu zvinoratidzirwa nehupamhi hwepamusoro uye simba guru.Kudhinda kweSLM kwakanyanyisa-simba, uye imwe neimwe yehupfu yesimbi inofanira kupiswa kusvika pakunyunguduka kwesimbi.Iyo tembiricha yepamusoro inokonzeresa kushushikana mukati me SLM yekupedzisira yakadhindwa zvinhu, izvo zvinogona kukanganisa ma mechanika echikamu.
JSAdd 3D 's simbi anodhinda anopihwa nevanozivikanwa vagadziri vepamba, uye yayo3D simbi yekudhinda masevhisiyakawedzera kumisika yemhiri kwemakungwa pasi rese, uko mhando uye nguva dzekutumira dzinonyatsozivikanwa nevatengi vekunze, kunyanya muEurope, America, Japan, Italy, Spain neSouth 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.
Kana iwe uchida kuziva rumwe ruzivo uye uchida kugadzira 3d printing modhi, ndapota tauraJSADD 3D Mugadziringuva dzese.
