Hauv kev lag luam hlau3D luam ntawv, cov txheej txheem raws li cov hmoov sib sau, xws li SLM, SLS, EBM, thiab lwm yam, feem ntau paub, tab sis kev tshawb fawb ntawm hlau paste luam ntawv hauv kev lag luam yog me me. Nws kuj tseem yog raws li kev tshawb fawb hauv cov tsev kawm qib siab, thiab cov ntawv thov ntawm cov txheej txheem luam ntawv hauv kev ua lag luam tsis muaj ntau.
Mantle, lub tuam txhab kev lag luam 3D luam tawm txawv teb chaws, xaiv cov ntawv luam tawm hlau luam tawm raws li lawv cov kev tshawb fawb, uas zoo ib yam li FDM thev naus laus zis, tsuas yog cov khoom hloov pauv ntawm cov khoom siv hlau / cov khoom rau hlau muab tshuaj. Lub tuam txhab co-founder thiab tus thawj saib xyuas kev tshawb fawb, Dr. Steve Connor, tau piav qhia meej txog cov laj thawj vim li cas nws lub tuam txhab siv slurry ua cov khoom siv hauv nws lub tshuab luam ntawv hlau 3D, tsis yog filaments, hmoov lossis kua li yuav luag tag nrho lwm cov hlau 3D tshuab luam ntawv manufacturers. siv.
Technical txoj cai
Mantle's TrueShape thev naus laus zis luam tawm, duab thiab sinters precision hlau qhov chaw los ntawm CAD cov ntaub ntawv ntawm ib feem ntawm lub sijhawm thiab tus nqi ntawm kev tsim khoom ib txwm muaj.
Cov txheej txheem kev muab faib ua peb kauj ruam: luam ntawv, txiav thiab sintering. Ua ntej, cov khoom siv Flowable hlau Paste yog luam tawm rau hauv cov duab ntawm ib feem uas siv qhov kev tso tawm qhov tseeb thiab lub taub hau extrudation-based printhead. Nyob rau tib lub sijhawm, ib lub cuab yeej siv los txiav cov txheej txheem ntawm kev kub ceev, txhim kho qhov chaw tiav thiab nthuav dav ntawm ib feem. Thaum kawg, nyob rau hauv lub qhov cub kub kub, ib feem yog rhuab mus rau ib tug kub me ntsis hauv qab nws melting point, melting mus rau hauv ib tug ntom khoom hlau ib feem.
Mantle, raws li ib tug tshiab startup nyob rau hauv lub tshav pob ntawm 3D luam ntawv, tau maj mam los rau hauv lub qhov muag rau pej xeem tsis ntev los no, uas yog muaj feem xyuam rau lub fact tias lawv lub tuam txhab tsis tau ua ntau yam ntawm cov khoom exhibitions. Mantle txoj kev lag luam kev lag luam yog cov cuab yeej siv hlau, thiab lawv tag nrho cov txheej txheem, nrog rau cov txheej txheem hlau 3D luam tawm, kuj tau tsim nyob ib ncig ntawm lub khw no.
Nyob rau hauv luv luv, tus txheej txheem yam ntxwv ntawm Mantle yog siv ib tug slurry extruder rau precisely deposit hlau slurry, thiaj li mus cuag cov nyhuv ntawm billet. Cov ntawv tso nyiaj ntsuab tau muab tso rau hauv qhov cub kom sov kom tshem tawm cov binder thiab cov khoom hlau sintered ua ke ua ntej CNC milling txiav txim ua kom du nto. Qhov no rov ua txheej txheej los ntawm txheej kom txog thaum cov khoom tsim.
Mantle, tsis zoo li feem ntau 3D tshuab luam ntawv tsim, tsis ua raws li cov qauv ntawm kev pib nrog cov thev naus laus zis thiab tom qab ntawd nrhiav kev lag luam. Hloov chaw, lawv xaiv lub khw ua ntej thiab tsuas yog tom qab ntawd tsom rau qhov teeb meem thev naus laus zis.
Hlau 3D luam ntawv yog tam sim no siv dav siv tshuab, nrog ntau tus neeg muag khoom muab cov khoom lag luam. Feem ntau cov tuam ntxhab xaiv siv cov txheej txheem hmoov txaj melting (PBF), qhov twg cov hmoov yog xaiv yaj txheej los ntawm txheej los ntawm kev txav lub zog hluav taws xob. Lwm cov txheej txheem hlau tsim muaj xws li luam tawm los ntawm cov kua hlau nanoparticles (xws li XJet) thiab cov hlau purity siab (xws li coaxial hlau pub laser vuam).
