Cov khoom tsim cov khoom siv polymer xav tau ntau yam zoo raws li lawv lub hom phiaj, qee qhov tuaj yeem muab los ntawm kev siv cov khoom siv polymer uas muaj ntau yam ntawm ntau yam ntaub ntawv.
Ib ceg ntawm kev tsim khoom ntxiv (AM), hu ua 3D luam ntawv, yog cov cuab yeej siv thev naus laus zis uas sib xyaw cov ntaub ntawv los tsim cov khoom raws li 3D qauv cov ntaub ntawv.
Yog li ntawd, cov pov tseg uas tsim los ntawm cov txheej txheem no kuj yog me me.3D tshuab luam ntawv yog tam sim no siv ntau yam kev siv, suav nrog kev tsim khoom loj ntawm ntau yam khoom, thiab qhov kev siv tsuas yog nce ntxiv.
Lub tshuab no tam sim no tuaj yeem siv los tsim cov khoom siv nrog cov txheej txheem nyuaj, cov khoom siv hnyav, thiab cov qauv tsim kho tau.Tsis tas li ntawd, 3D luam ntawv muaj qhov zoo ntawm kev ua tau zoo, kev ruaj khov, ntau yam thiab kev pheej hmoo tsawg.
Ib qho tseem ceeb tshaj plaws ntawm cov thev naus laus zis no suav nrog kev xaiv qhov tsis zoo vim tias lawv muaj kev cuam tshuam zoo rau cov khoom, xws li nws cov duab, qhov loj me, qhov cua txias, thiab thermal gradient.Cov qualities ces cuam tshuam rau evolution ntawm lub microstructure, nws cov yam ntxwv thiab tsis xws luag.
Kev kawm tshuab tuaj yeem siv los tsim kom muaj kev sib raug zoo ntawm cov txheej txheem txheej txheem, microstructure, cov khoom zoo, muaj pes tsawg leeg, qhov tsis xws luag, thiab kev siv tshuab zoo ntawm cov khoom luam tawm tshwj xeeb.Cov kev sib txuas no tuaj yeem pab txo qis cov kev sim siab uas yuav tsum tau ua los tsim cov khoom lag luam zoo.
High-density polyethylene (HDPE) thiab polylactic acid (PLA) yog ob feem ntau siv polymers hauv AM.PLA yog siv los ua cov khoom tseem ceeb rau ntau daim ntawv thov vim nws muaj kev ruaj ntseg, kev lag luam, biodegradable thiab muaj cov khoom zoo heev.
Cov yas rov ua dua tshiab yog qhov teeb meem loj uas tau ntsib lub ntiaj teb;Yog li ntawd, nws yuav muaj txiaj ntsig zoo los koom nrog cov yas rov ua dua tshiab rau hauv 3D luam ntawv txheej txheem.
Raws li cov ntaub ntawv luam tawm txuas ntxiv mus rau hauv lub liquefier, qhov kub thiab txias yog tswj ntawm qhov sib xws thaum lub sij hawm fused filament manufacturing (FFF) deposition (ib hom 3D luam ntawv).
Yog li ntawd, lub molten polymer yog ejected los ntawm lub nozzle los ntawm lub siab txo.Surface morphology, yield, geometric raug, mechanical zog, thiab nqi yog tag nrho cov cuam tshuam los ntawm FFF variables.
Tensile, compressive cuam tshuam los yog dabtsi yog khoov lub zog thiab luam ntawv kev taw qhia yog suav hais tias yog cov txheej txheem tseem ceeb tshaj plaws uas cuam tshuam rau cov qauv FFF.Hauv txoj kev tshawb no, FFF txoj kev tau siv los npaj cov qauv;rau qhov sib txawv filaments tau siv los tsim cov qauv txheej.
a: ML kev kwv yees parameter optimization qauv ntawm 3D tshuab luam ntawv hauv cov qauv 1 thiab 2, b: ML twv ua ntej parameter optimization qauv ntawm 3D tshuab luam ntawv hauv cov qauv 3, c: ML twv ntsuas parameter optimization qauv ntawm 3D tshuab luam ntawv hauv cov qauv 4 thiab 5. Duab qhov chaw: Hossain , MI, thiab lwm yam.
3D tshuab luam ntawv tuaj yeem muab cov khoom lag luam zoo tshaj plaws uas tsis tuaj yeem ua tiav los ntawm cov txheej txheem ntau lawm.Vim yog txoj kev tsim khoom tshwj xeeb ntawm 3D luam ntawv, qhov zoo ntawm cov khoom tsim tau cuam tshuam zoo heev los ntawm kev tsim thiab txheej txheem sib txawv.
Kev kawm tshuab (ML) tau siv ntau txoj hauv kev hauv kev tsim khoom ntxiv los txhim kho tag nrho txoj kev loj hlob thiab kev tsim khoom.Cov ntaub ntawv-raws li kev tsim qauv zoo tshaj plaws rau FFF thiab lub moj khaum rau kev txhim kho FFF tivthaiv tsim tau tsim.
Cov kws tshawb fawb tau kwv yees qhov kub ntawm lub nozzle nrog kev pab ntawm cov lus qhia txog kev kawm tshuab.ML thev naus laus zis kuj tseem siv los laij cov tshuab luam ntawv kub thiab luam ntawv ceev;tib qhov loj yog teem rau tag nrho cov qauv.
Cov txiaj ntsig tau pom tias qhov fluidity ntawm cov khoom ncaj qha cuam tshuam rau qhov zoo ntawm 3D luam tawm.Tsuas yog qhov zoo ntawm nozzle qhov kub thiab txias tuaj yeem ua kom muaj qhov xav tau fluidity ntawm cov khoom.
Hauv kev ua haujlwm no, PLA, HDPE thiab cov khoom siv rov ua dua tshiab yog sib xyaw nrog TiO2 nanoparticles thiab siv los tsim cov khoom lag luam uas tsis muaj nqi 3D los ntawm kev lag luam melted filament manufacturing 3D printers thiab filament extruders.
Cov yam ntxwv filaments yog cov tshiab thiab siv graphene los tsim cov txheej txheem dej tsis zoo, uas tuaj yeem txo qhov kev hloov pauv hauv cov khoom siv kho tshuab ntawm cov khoom tiav.Sab nraud ntawm 3D luam tawm tivthaiv kuj tuaj yeem ua tiav.
Lub hom phiaj tseem ceeb ntawm txoj haujlwm no yog txhawm rau nrhiav txoj hauv kev kom ua tiav cov khoom lag luam txhim khu kev qha thiab muaj txiaj ntsig zoo thiab lub cev zoo hauv 3D cov khoom luam tawm piv rau cov khoom luam 3D uas feem ntau tsim.Cov txiaj ntsig thiab kev siv ntawm qhov kev tshawb fawb no tuaj yeem ua rau txoj hauv kev rau kev txhim kho ntau yam kev lag luam ntsig txog kev lag luam.
Nco ntsoov nyeem: Cov nanoparticles twg yog qhov zoo tshaj plaws rau kev tsim khoom thiab 3D luam ntawv?
