Kev luam tawm ntawm lub tshuab luam ntawv 3D niaj hnub yog ua los ntawm cov xov yas tau los ntawm ntau yam ntaub ntawv. High-zoo filament rau lub tshuab luam ntawv 3D yog tsim los ntawm cov khoom siv xws li ABS, PLA, HIPS. Kev siv cov ntaub ntawv zoo raw khoom tso cai rau cov tuam txhab tsim cov khoom siv tshwj xeeb hauv kev ua haujlwm thiab kev ua haujlwm, raws li ntau yam tuaj yeem ua.
Main Materials
Kev tsim cov filament rau lub tshuab luam ntawv 3d feem ntau yog raws li ob yam khoom - ABS yas thiab PLA (polylactide). Ob qho khoom ua tau raws li qhov yuav tsum tau ua ntawm biodegradability, biocompatibility, thermoplasticity thiab yog raws li cov peev txheej txuas mus ntxiv, xws li pob kws thiab qab zib. Cov khoom siv raw yog qhov zoo tagnrho rau ntau yam khoom siv hauv kev kho mob, zaub mov thiab lwm yam lag luam.
Cov filament rau luam ntawv ntawm lub tshuab luam ntawv 3D yuav tsum yog cov khoom zoo nyob rau hauv thiaj li yuav tau txais cov khoom kawg kom txaus siab rau cov khoom ua tau zoo. Yas filament rau lub tshuab luam ntawv 3d yog ib hom khoom siv yooj yim dua rau cov khoom siv. Piv rau granules, vim nws yooj yim los hloov, nws tuaj yeem luam tawm ntau xim ib zaug, thiab cov khoom siv tau qis dua.
Production Features
3D luam ntawv yog kim heev, vim tus nqi siab ntawm cov khoom siv lawv tus kheej. Txhawm rau txo tus nqi luam ntawv, cov kws tsim khoom tsim cov khoom siv portable rau kev siv hauv tsev.
Yog li, koj tuaj yeem tsim cov xov rau 3d tshuab luam ntawv nrog koj tus kheej tes pheej yig dua. Technologically, cov txheej txheem no tsis yog qhov nyuaj heev, qhov tseem ceeb tshaj plaws yog saib xyuas qhov kub thiab txias thiab qee qhov sib npaug ntawm qhov sib tov. Nyob rau hauv tus qauv version, zus tau tej cov xov yog nqa tawm nyob rau hauv ob peb theem:
- Ua ntej, thawj qhov sib xyaw yog npaj. Txhawm rau kom tau txais cov khoom siv nrog qhov xav tau, nws yog ib qho tseem ceeb uas yuav tsum sib xyaw cov khoom tseem ceeb hauv qhov tsim nyog. Cov xov tau txais ib qho ntxoov ntxoo vim qhov sib ntxiv ntawm cov tshuaj pleev xim xim pigments. Qhov tseeb ntawm kev faib ua feem yog qhov lav tias cov xim ntawm cov xov thiab, yav tom ntej, ntawm cov polymer nws tus kheej yuav ruaj khov.
- Loading rau hauv bunker. Tom qab kev npaj, cov sib tov nkag mus rau hauv lub tank dispensing, thiab ces pub rau hauv lub extruder.
- Npaj ib homogeneous pawg. Tag nrho cov khoom uas muab tso rau hauv lub extruder yog tov kom txog thaum ib tug yas loj tsim.
- Tshuaj yas filament rau 3d tshuab luam ntawv. Ib homogeneous loj yog nias los ntawm ib tug tshwj xeeb nozzle nrog ib tug ntsia hlau. Nws muaj ib txoj kab uas hla, uas yog sib npaug rau lub thickness ntawm yav tom ntej xov.
- Cov xov yog txias thiab qhuav. viscous yas twb nyob rau hauv daim ntawv ntawm threads nkag mus rau hauv da dejnrog dej kom txias lawv. Lawv kuj tau yooj yim. Los ntawm lub txias txias, cov xov tiav yog pub los ntawm cov menyuam tshwj xeeb rau lub tshuab ziab khaub ncaws, qhov chaw nws qhuav nyob rau hauv cov cua kub.
Tom qab ziab, cov hlua rau lub tshuab luam ntawv 3D tau raug mob rau ntawm lub spool. Vim nws qhov yooj, lub zog, plasticity, nws yog qhov zoo tagnrho rau siv rau txhua hom tshuab luam ntawv. Txoj kab uas hla ntawm cov xov yog txawv - 1.75 hli los yog 3 hli, uas txawv nyob ntawm seb lub nozzles siv nyob rau hauv cov khoom. Kev siv ntau yam xim ua rau nws muaj peev xwm ua tiav ntau yam xim rau cov xov yas.
Filabot Original
Nws muaj peev xwm ua cov filaments los ntawm yas rau lub tshuab luam ntawv 3D, tab sis rau qhov no koj yuav tsum tsim koj tus kheej extruder. Yuav ua li cas rau qhov no, peb yuav qhia me ntsis tom qab. Tsis tas li ntawd, txoj hauv kev yooj yim tshaj plaws yog mus yuav cov khoom lag luam npaj txhij thiab cov khoom siv txawb, piv txwv li, Filabot Original. Cov khoom siv 3D tshuab luam ntawv filament no tuaj yeem tsim cov yas filament nrog txoj kab uas hla ntawm 1mm, 75mm lossis 3mm. Cov khoom siv ua haujlwm nrog ntau yam yas - ABS, PLA thiab HIPS.
Cov cuab yeej ua haujlwm nrog cov yas granules, tso cai rau koj tswj qhov kub thiab txias. Nws muaj lub lim kom tiv thaiv kom tsis txhob muaj cov kab mob sib kis. Universal hwj chim txaus siv lub cuab yeej hauv tsev. Dyes yog siv los muab cov xim sib txawv. Hauv kev pom zoo ntawm kev xaiv cov cuab yeej no hais txog nws cov khoom lag luam siab: nws yuav siv sijhawm li 5 teev kom tau txais ib kilogram xov.
FilabotWee
Niaj hnub nimno 3d tshuab luam ntawv filament ntau lawm kab yog sawv cev los ntawm Filabot hom. Cov khoom siv nrog cov ntaub ntawv ntoo yog qhov pheej yig dua, thiab koj tuaj yeem yuav nws ob qho tib si npaj thiab ua cov khoom siv rau kev sib sau ua ke ntawm koj tus kheej. Ib yam li cov cuab yeej tau piav qhia saum toj no, qhov no ua haujlwm raws li hom nrov ntawm cov yas. Ib tug dav xim palette yog tiav siv granular dyes. Koj tuaj yeem ntxiv granulated carbon fiber rau qhov sib tov, uas yuav ua rau kom lub zog ntawm cov pas nrig tiav. Tus qauv yog nruab nrog ob lub nozzles sib hloov, yog li koj tuaj yeem tsim cov hlua rau lub tshuab luam ntawv 3D nrog txoj kab uas hla ntawm 1.075 lossis 3 hli.
Filastruder
Nyob hauv kev lag luam 3D, Filastruder extruder paub txog nws ntau yam sib dhos, ua rau txhua tus tuaj yeem ua cov yas filament hauv tsev. Kev xav tau tsim thiab siv tau yooj yim, tus qauv no zoo tagnrho rau kev siv extrusion.
Muaj cov cuab yeej zoo li no hauv tsev, koj tuaj yeem teeb tsa kev tsim cov xov rau 3d tshuab luam ntawv nrog koj tus kheej tes. Qhov tsuas yog caveat yog kom raug xaiv cov proportions ntawm cov khoom siv, dyes. Nyob rau hauv tsuas yog 12 teev ntawm kev ua haujlwm, cov cuab yeej muaj peev xwm ua tau 1 kg ntawm filament, thaum kawg cov khoom tsim tau nyob ntawm qhov tsis xws li nozzle txoj kab uas hla, extrusion kub, thiab cov ntaub ntawv siv.
Lyman extruder
Lub tshuab no yog qhov tshwj xeeb uas nws yog ib qho ntawm thawj zaug siv los tsim cov pas nrig yas. Nws yog noteworthy tias tus tsim ntawm cov khoom yeej lub ntsiab nqi zog ntawmKev sib tw Desktop Factory hauv 2013. Vim yog qhov yooj yim ntawm kev tsim, cov khoom siv nws tus kheej tau hloov mus ua qhov pheej yig tshaj plaws hauv kev sib piv nrog lwm cov analogues. Lwm qhov tseeb nthuav yog tias tag nrho cov lus qhia yog nyob rau hauv pej xeem sau. Koj tuaj yeem rub tawm cov qauv tsim thiab tsim ib qho extruder los ua 3D tshuab luam ntawv filament hauv tsev.
Kev ua cov khoom siv hauv tsev
Ntau zaus, cov neeg uas xav ua haujlwm nrog 3D tshuab luam ntawv pib tsim cov khoom siv los tsim cov yas filament lawv tus kheej txhawm rau txo lawv cov nqi. Qhov tseeb, cov cuab yeej zoo li no, txawm tias lawv cov txiaj ntsig zoo thiab muaj txiaj ntsig, tseem tsis zoo:
- xov yuav tsis zoo, tsis txaus lossis tsis raug, uas yuav cuam tshuam rau kev deformation ntawm cov khoom kawg lossis txawm tias tsis muaj peev xwm luam ntawv;
- thaum cua sov, yas tuaj yeem tso cov khoom tsis zoo uas yuav tsum tau ua pa thaum lub sijhawm luam ntawv thiab thaum ua cov khoom siv raw;
- Kev rov ua dua tshiab ntawm cov yas dyed yuav tsis tuaj yeem ua tau vim koj yuav tsis paub qhov muaj pes tsawg leeg ntawm cov yas thiab cov dye.
Ua-nws-koj tus kheej extruders nyuaj los ua cov yas zoo tiag tiag. Yog li ntawd, nws yog qhov zoo dua los yuav cov khoom siv nqa tau los ntawm cov khoom lag luam ntseeg siab.
Txog txoj hauv kev kom tau cov xov pheej yig
Yuav tsim cov filament rau lub tshuab luam ntawv 3d, koj yuav tsum tau siv cov khoom yas ABS npaj txhij. Tab sis nws kim heev thiab kim, yog li nyob hauv tsevcov xwm txheej, koj tuaj yeem tsim cov khoom siv los ntawm lub raj mis yas zoo tib yam. Lub ntsiab ntawm qhov kev tshwm sim yog yooj yim:
- PET lub raj mis crushed rau hauv flakes;
- qhov tshwm sim huab cua sov kom txog thaum nws ncav cuag lub melting point;
- dhau ntawm lub qhov ntawm lub tshuab extruder, cov xov ntawm txoj kab uas xav tau yog extruded (lub taub hau yog lub luag haujlwm rau nws);
- Cov ntaub yas uas tau tshwm sim yog txias los ntawm huab cua ntws thiab tom qab ntawd raug mob rau lub nruas.
Feem ntau, kev teeb tsa kev tsim khoom tsis yooj yim li nws zoo li. Nws yog qhov nyuaj dua los nrhiav cov ntaub ntawv zoo los ua kom cov filament muaj zog, txhim khu kev qha, nyab xeeb thiab haum rau 3D luam ntawv daim ntawv thov.
Hais txog kev rov ua dua tshiab. Hauv qee lub tebchaws, cov phiaj xwm kev sib raug zoo tau raug coj los ua dua tshiab lub kaus mom yas. Cov kws tshawb fawb Spanish tau hais kom tsim cov xov rau kev luam tawm los ntawm lawv, txij li lub kaus mom lub raj mis yog ua los ntawm cov thermoplastic polyethylene high-density. PET-based 3D luam ntawv yog qhov tshwm sim nrov uas tso cai rau koj los tsim lwm txoj hauv kev rau PLA lossis ABS yas ntawm tus nqi qis heev. Qhov teeb meem nkaus xwb yog cov txheej txheem no, nrog rau nws txoj kev lag luam, ntev dhau lawm, thiab koj yuav tsum tau ua haujlwm hnyav los tsim cov xov hauv tus nqi zoo.
