Amashanyarazi ya elegitoronike(EBM)
Gukoresha amashanyarazi ya elegitoronike (EBSM) Ihame
Bisa na laser guhitamo icyaha noGuhitamo Laser Gushongainzira, tekinoroji ya elegitoronike yatoranijwe yo gushonga (EBSM) nubuhanga bwihuse bwo gukora bukoresha ingufu za elegitoronike zifite ingufu nyinshi kandi zihuta kugirango bahitemo ifu yicyuma, bityo gushonga no gukora ibikoresho byifu.
Inzira ya EBSM tekinoroji niyi ikurikira ： ubanza, gukwirakwiza urwego rwifu yifu ikwirakwiza indege;hanyuma, mugenzuzi wa mudasobwa, urumuri rwa elegitoronike rushobora gushonga ukurikije amakuru yumwirondoro wambukiranya ibice, hanyuma ifu yicyuma igashonga hamwe, igahuzwa nigice cyashizweho hepfo, hanyuma ikarundarunda kumurongo kugeza igice cyose cyuzuye. gushonga;Hanyuma, ifu irenzeho ikurwaho kugirango itange ibicuruzwa byifuzwa-bitatu.Ikimenyetso nyacyo cyo gusikana cya mudasobwa yo hejuru cyoherezwa ku ngogo ya deflection nyuma ya digitale-igereranya no guhinduranya ingufu, kandi urumuri rwa elegitoronike ruyobowe nigikorwa cyumurima wa rukuruzi rwakozwe na voltage ihindagurika kugirango ugere kumashanyarazi. .Nyuma yimyaka irenga icumi yubushakashatsi, usanga ibipimo bimwe na bimwe nkibikorwa bya elegitoroniki yumuriro, byibanda kumyanya, igihe cyibikorwa, ubunini bwifu, kwihuta kwumuvuduko, hamwe nuburyo bwo gusikana bikorwa mubushakashatsi bwa orthogonal.Igihe cyibikorwa gifite uruhare runini mugushinga.
Ibyizaya EBSM
Ikoreshwa rya elegitoroniki ikora ibyuma bikoresha tekinoroji ikoresha ingufu za elegitoronike nkisoko yo gutunganya ubushyuhe.Gukora scan birashobora gukorwa nta inertie yubukanishi ukoresheje coil ya magnetique deflection, kandi ibidukikije bya vacuum byumuriro wa electron birashobora kandi kubuza ifu yicyuma kuba okiside mugihe cyamazi yo gucumura cyangwa gushonga.Ugereranije na lazeri, urumuri rwa elegitoronike rufite ibyiza byo gukoresha ingufu nyinshi, ubujyakuzimu bunini bwibikorwa, igipimo kinini cyo kwinjiza ibintu, gutuza no gukora bike hamwe nigiciro cyo kubungabunga.Inyungu zikoranabuhanga rya EBM zirimo gukora neza cyane, guhindura igice gito, ntagikeneye inkunga yicyuma mugihe cyo gukora, microstructure ya denser, nibindi.Gutandukanya ibyuma bya elegitoronike no kugenzura byihuta kandi byoroshye.Gutandukana kwa lazeri bisaba gukoresha indorerwamo yinyeganyeza, kandi umuvuduko windorerwamo uhindagurika byihuta cyane iyo laser isikana kumuvuduko mwinshi.Iyo imbaraga za laser ziyongereye, galvanometero isaba sisitemu yo gukonjesha igoye, kandi uburemere bwayo bwiyongera cyane.Nkigisubizo, mugihe ukoresheje imbaraga zo gusikana hejuru, umuvuduko wo gusikana laser uzaba muke.Iyo gusikana urwego runini, guhindura uburebure bwa laser nabyo biragoye.Gutandukana no kwibanda kumurongo wa electron bikorwa numurima wa magneti.Gutandukana no kwibanda ku burebure bwa electron irashobora kugenzurwa vuba kandi byoroshye muguhindura ubukana nicyerekezo cyikimenyetso cyamashanyarazi.Sisitemu yibanda kuri electron ntabwo izahungabanywa no guhumeka ibyuma.Iyo gushonga ibyuma hamwe na laseri hamwe nibiti bya elegitoronike, imyuka yicyuma izakwirakwira ahantu hose hagaragara kandi igatwikira hejuru yikintu icyo aricyo cyose gihuye na firime yicyuma.Gutandukana no kwibanda kumirasire ya electron byose bikorwa mumashanyarazi, ntabwo rero bizagira ingaruka kumyuka yicyuma;ibikoresho bya optique nka laser galvanometero byanduzwa byoroshye no guhumeka.
Laser Metal Kubitsa(LMD)
Laser Metal Deposition (LMD) yatanzwe bwa mbere na Laboratoire y'igihugu ya Sandia muri Amerika mu myaka ya za 90, hanyuma itera imbere mu bice byinshi by'isi.Kubera ko kaminuza n'ibigo byinshi bikora ubushakashatsi mu bwigenge, iri koranabuhanga Hariho amazina menshi, nubwo amazina atari amwe, ariko amahame yabo ni amwe.Mugihe cyo kubumba, ifu ikusanyirizwa mu ndege ikora ikoresheje nozzle, kandi urumuri rwa lazeri narwo rukusanyirizwa aho bigeze, kandi ifu n’ibikorwa by’urumuri birahurirana, kandi ikintu cyambitswe ibintu kiboneka binyuze mu kazi. cyangwa nozzle.
Ikoranabuhanga rya LENS ikoresha kilowatt-urwego rwa laseri.Bitewe na lazeri nini yibandaho, mubisanzwe birenga 1mm, nubwo ibyuma bifatanye byuma byuma bishobora kuboneka, uburinganire bwabyo hamwe no kurangiza neza ntabwo ari byiza cyane, kandi nibindi bisabwa birakenewe mbere yo kubikoresha.Kwambika lazeri ni ibintu bigoye byumubiri na chimique metallurgjique, kandi ibipimo byuburyo bwo kwambara bigira uruhare runini kumiterere yibice byambaye.Ibipimo byerekana muburyo bwa lazeri harimo ingufu za laser, diameter yibibara, umubare wa defocusing, umuvuduko wo kugaburira ifu, umuvuduko wo gusikana, ubushyuhe bwa pisine yashongeshejwe, nibindi, bigira ingaruka zikomeye kumuvuduko wa dilution, kumeneka, gukomera hejuru no guhuza ibice byambaye. .Igihe kimwe, buri kintu nacyo kigira ingaruka kuri buriwese, ninzira igoye cyane.Uburyo bukwiye bwo kugenzura bugomba gukoreshwa kugirango hagenzurwe ibintu bitandukanye bigira ingaruka muburyo bwemewe bwo kwambara.
BitaziguyeIcyuma Cyuma S.intering(DMLS)
Hariho uburyo bubiri kuriSLSgukora ibice byicyuma, bumwe nuburyo butaziguye, ni ukuvuga, SLS yifu ya polymer yometseho ifu;ubundi ni uburyo butaziguye, ni ukuvuga, Direct Metal Laser Sintering (DMLS) .Kubera ko ubushakashatsi bwerekeranye no gucana lazeri itaziguye ifu yicyuma bwakorewe muri kaminuza ya Chatofci i Leuvne mu 1991, gucumura mu buryo butaziguye ifu yicyuma kugirango ibe ibice bitatu. na SLS inzira nimwe mumigambi yanyuma yo kwihuta prototyping.Ugereranije na tekinoroji ya SLS itaziguye, inyungu nyamukuru yuburyo bwa DMLS ni ugukuraho ibintu bihenze kandi bitwara igihe mbere yo kuvurwa na nyuma yubuvuzi.
Ibiranga ya DMLS
Nishami ryikoranabuhanga rya SLS, tekinoroji ya DMLS ifite ihame rimwe.Ariko, biragoye gukora neza ibice byicyuma bifite imiterere igoye hakoreshejwe ikoranabuhanga rya DMLS.Mu isesengura rya nyuma, biterwa ahanini ningaruka za "spheroidisation" hamwe no guhindura imikorere yifu yicyuma muri DMLS.Spheroidisation ni ibintu byerekana uburyo ubuso bwamazi yicyuma gishongeshejwe buhinduka mubuso bwa serefegitura munsi yimiterere yimiterere hagati yicyuma cyamazi nuburyo bukikije kugirango hagire sisitemu igizwe nubuso bwamazi yashongeshejwe hamwe nubuso bwa ikigereranyo gikikije ingufu nkeya.Spheroidisation izatuma ifu yicyuma idashobora gukomera nyuma yo gushonga kugirango ikore ikidendezi gikomeza kandi cyoroshye, bityo ibice byakozwe birarekuye kandi byoroshye, bikaviramo kunanirwa kubumba.Bitewe nubusumbane bukabije bwifu yicyuma kimwe cyicyuma mugice cyamazi yo gucumura, ingaruka ya "spheroidisation" irakomeye cyane, kandi diameter ya serefegitire iba nini cyane kuruta diameter yibice by'ifu, biganisha ku mubare munini wa imyenge mu bice byacumuye.Kubwibyo, DMLS yifu yicyuma kimwe gusa ifite inenge igaragara, kandi akenshi bisaba kuvurwa nyuma, ntabwo ari imyumvire nyayo yo "gucumura neza".
Kugirango tuneshe ibintu bya "spheroidisation" ya pompe yicyuma kimwe DMLS hamwe nibisubizo byavuyemo nko guhinduranya sinteri hamwe nubucucike bworoshye, birashobora kugerwaho mubisanzwe ukoresheje ifu yibice byinshi byibyuma bifite aho bishonga cyangwa ukoresheje ifu ibanziriza. .Sisitemu yibice byinshi byifu ya sisitemu igizwe nibisanzwe byo gushonga hejuru, ibyuma byo gushonga hasi hamwe nibintu bimwe byongeweho.Ifu yo hejuru yo gushonga icyuma nkicyuma cya skeleton gishobora kugumana intangiriro yacyo muri DMLS.Ifu yicyuma gike-ifu ikoreshwa nkicyuma gihuza, gishongeshwa muri DMLS kugirango kibe icyiciro cyamazi, hamwe namakoti yicyiciro cyamazi yatose, atose kandi ahuza ibice bikomeye byicyuma kugirango agere kubucucike.
Nka sosiyete iyoboye UbushinwaSerivisi yo gucapa 3Dinganda,JSADD3D ntazibagirwa umugambi wacyo wambere, kongera ishoramari, guhanga no guteza imbere ikoranabuhanga ryinshi, kandi bizera ko bizazana uburambe bushya bwo gucapa 3D.
