Thaum peb tham txog kev tsim khoom thiab cov khoom siv ntxiv, peb feem ntau xav txog cov yas lossis hlau.Txawm li cas los xij,3D luam ntawvCov khoom sib xws tau loj hlob ntau xyoo dhau los.Tam sim no peb tuaj yeem siv ntau yam khoom siv los tsim cov khoom, los ntawm ceramics mus rau zaub mov mus rau hydrogels uas muaj cov qia hlwb.Ntoo kuj yog ib qho ntawm cov khoom siv nthuav dav.
Tam sim no, cov ntaub ntawv ntoo tuaj yeem ua tau zoo nrog filament extrusion thiab txawm tias hmoov txaj tshuab, thiab ntoo 3D luam ntawv tau dhau los ua neeg nyiam.
Raws li tsab ntawv tshaj tawm los ntawm Nature magazine, tib neeg tau poob 54% ntawm tag nrho cov ntoo hauv ntiaj teb.Deforestation yog ib qho kev hem thawj tiag tiag niaj hnub no.Nws yog ib qho tseem ceeb uas yuav tau rov xav txog txoj kev uas peb haus ntoo.Kev tsim khoom ntxiv tuaj yeem yog tus yuam sij rau kev siv ntoo kom ruaj khov, vim tias nws yog cov cuab yeej tsim khoom siv uas tsuas yog siv cov khoom tsim nyog, thiab tuaj yeem siv cov khoom siv rov ua dua tshiab los tsim cov khoom.Yog li ntawd, peb tuaj yeem 3D luam tawm qhov chaw.Yog tias lawv tsis muaj txiaj ntsig ntxiv lawm, peb tuaj yeem hloov lawv rov qab rau cov ntaub ntawv raw los pib lub voj voog tsim khoom tshiab.

Extruded ntoo3D luam ntawv txheej txheem
Ib txoj hauv kev los luam ntoo hauv 3D yog extrude filaments.Nws yuav tsum raug sau tseg tias cov ntaub ntawv no tsis yog 100% ua los ntawm ntoo.Lawv yeej muaj 30-40% ntoo fiber ntau thiab 60-70% polymer (siv raws li nplaum).Ntoo 3D luam ntawv txheej txheem nws tus kheej kuj tseem nthuav heev.Piv txwv li, koj tuaj yeem kuaj qhov sib txawv ntawm cov xov hlau no los tsim cov xim sib txawv thiab ua tiav.Hauv lwm lo lus, yog tias lub extruder nce mus txog qhov kub siab, cov ntoo fiber ntau yuav hlawv, ua rau lub suab tsaus dua hauv cov khib nyiab.Tab sis nco ntsoov, cov khoom no yog heev flammable.Yog hais tias lub nozzle kub dhau heev lawm thiab cov hlau extrusion ceev tsis ceev txaus, cov ntawv luam tawm yuav puas los yog txawm ntes hluav taws.
Lub ntsiab kom zoo dua ntawm ntoo txhob lo lo ntxhuav yog tias nws zoo nkaus li, hnov ​​thiab tsw zoo li cov khoom ntoo.Tsis tas li ntawd, cov ntawv luam tawm tuaj yeem yooj yim pleev xim, txiav thiab polished kom lawv qhov chaw zoo dua.Txawm li cas los xij, ib qho ntawm qhov tsis zoo tshaj plaws yog tias nws yog cov khoom tawg yooj yim dua li cov qauv thermoplastic.Yog li ntawd, lawv yooj yim dua tawg.
Feem ntau hais lus, cov khoom siv no yuav tsis siv rau hauv kev lag luam ib puag ncig, tab sis rau lub ntiaj teb tsim, qhov twg nws yog siv los ua ib qho kev nyiam los yog cov khoom zoo nkauj.Qee cov tuam txhab ntoo fiber ntau suav nrog Polymaker, Filamentum, Colorfabb lossis FormFutura.
Kev siv ntoo hauv cov txheej txheem hmoov txaj
Rau kev tsim cov khoom ntoo, hmoov txaj tshuab kuj siv tau.Nyob rau hauv cov ntaub ntawv no, ib tug zoo heev xim av hmoov muaj li ntawm sawdust, thiab nto yog xuab zeb zoo li.Ib qho ntawm cov thev naus laus zis tseem ceeb tshaj plaws hauv daim teb no yog cov nplaum nplaum, uas yog nto moo tshaj plaws rau Desktop Hlau (DM).DM tau qhib lub qhov rooj tshiab hauv lub ntiaj teb kev tsim khoom ntxiv tom qab koom tes nrog Forust.Lub "Shop System Forest Edition" luam ntawv sib koom ua ke tsim los ntawm ob qho tib si tso cai rau cov neeg tuaj saib dav siv Binder Jetting rau ntoo 3D luam ntawv.
Lub tshuab luam ntawv no tuaj yeem 3D luam ntawv ua haujlwm kawg-siv cov khoom siv ntoo ua los ntawm cov ntoo siv dua tshiab.Lub tshuab tsim tiag tiag siv cov sawdust hais thiab cov nplaum hauv cov txheej txheem ntawm kev tswj xyuas lub computer.Siv cov txheej txheem tsim los ntawm txheej txheej, nws muaj peev xwm tsim cov khoom ntoo uas nyuaj rau kev ua tiav los ntawm cov txheej txheem rho tawm ib txwm thiab tsis muaj khib nyiab.Obviously, tus nqi ntawm cov tshuab no yuav ntau dua li cov txheej txheem filament extrusion.Txawm li cas los xij, qhov no tsim nyog xav txog vim tias qhov kawg tshwm sim yuav muaj qhov zoo ntawm qhov zoo tshaj qhov FFF luam tawm.
Ntxiv rau qhov raug suav tias yog hom kev tsim ntoo ntau dua, ntoo 3D luam ntawv kuj tuaj yeem daws tau ntau yam teeb meem.Qhov no suav nrog los ntawm kev kho dua tshiab ntawm keeb kwm mus rau kev tsim cov khoom kim heev, mus rau kev siv cov khoom siv ntuj no tseem tsis tau xav txog cov khoom tshiab.Vim tias nws yog cov txheej txheem digital, cov neeg siv tsis muaj kev txawj ntoo ntoo tuaj yeem txaus siab rau cov txiaj ntsig ntawm ntoo3D luam ntawv.
