Thaum ua haujlwm nrog PETG filament rau 3D luam ntawv, kev tswj dej noo yog qhov tseem ceeb rau kev ua tiav cov ntawv luam tawm zoo. PETG yog hygroscopic, txhais tau tias nws absorbs noo noo los ntawm huab cua, uas tuaj yeem ua rau luam tawm tsis xws li bubbling, stringing, thiab tsis zoo txheej adhesion. Lub tshuab ziab khaub ncaws PETG kom zoo ua kom koj cov filament tseem qhuav, txhim kho kev luam ntawv sib xws thiab lub zog. Hauv phau ntawv qhia no, peb yuav taug kev koj los ntawm cov kauj ruam los teeb tsa kojPETG tshuab ziab khaub ncawskom raug.

Vim li cas ziab PETG yog qhov tseem ceeb
PETG absorbs noo noo los ntawm ib puag ncig sai, tshwj xeeb tshaj yog nyob rau hauv cov huab cua ntub. Kev luam ntawv nrog damp PETG tuaj yeem ua rau ntau yam teeb meem, suav nrog:
• Tsis sib xws extrusion thiab txheej bonding
• Tsis zoo ntawm qhov chaw tiav thiab cov khoom qub uas tsis xav tau
• Muaj kev pheej hmoo ntawm nozzle clogging
Lub tshuab ziab khaub ncaws PETG tshem tawm cov dej noo ntau dhau ua ntej luam ntawv, tiv thaiv cov teeb meem no thiab ua kom cov ntawv luam tawm zoo.

Kauj ruam 1: Xaiv txoj cai PETG tshuab ziab khaub ncaws
Xaiv lub tshuab ziab khaub ncaws PETG yog qhov tseem ceeb rau kev pom zoo. Nrhiav cov yam ntxwv xws li:
• Kev tswj qhov kub thiab txias: PETG yuav tsum tau qhuav ntawm ib ncig ntawm 65 ° C (149 ° F) kom tshem tawm cov dej noo zoo yam tsis muaj qhov cuam tshuam cov filament.
• Kho lub sij hawm kom qhuav: Nyob ntawm cov av noo thiab filament raug, lub sij hawm ziab yuav txawv ntawm 4 mus rau 12 teev.
• Cov ntaub thaiv npog: Lub tshuab ziab khaub ncaws kom zoo zoo tiv thaiv kom tsis txhob ya raws.
Kauj ruam 2: Preheat lub PETG tshuab ziab khaub ncaws
Ua ntej muab cov filament rau hauv, preheat lub tshuab ziab khaub ncaws rau qhov pom zoo kub. Qhov no ua kom cov txheej txheem ziab pib tam sim ntawd thaum cov filament ntxiv.
Kauj Ruam 3: Load PETG Filament kom raug
Muab lub PETG spool nyob rau hauv lub tshuab ziab khaub ncaws, kom ntseeg tau tias cov filament tsis nruj heev los yog sib tshooj, vim qhov no tuaj yeem cuam tshuam rau huab cua thiab ziab kom qhuav. Yog tias koj lub tshuab ziab khaub ncaws muaj cov khoom siv ua ke, xyuas kom cov filament tuaj yeem tig tau zoo rau kev ziab kom zoo ib yam.
Kauj Ruam 4: Teem kom raug qhov ziab kom qhuav
Qhov zoo tshaj plaws ziab kub rau PETG yog nruab nrab ntawm 60 ° C thiab 70 ° C. Yog tias koj lub tshuab ziab khaub ncaws tso cai rau kev tswj qhov kub thiab txias, teem rau 65 ° C kom pom cov txiaj ntsig zoo. Tsis txhob siab tshaj 70 ° C, vim tias qhov kub siab dua tuaj yeem ua rau filament deformation.
Kauj ruam 5: Txiav txim siab lub sij hawm ziab
Lub sij hawm ziab yog nyob ntawm qhov noo noo nyob rau hauv filament:
• Rau cov spools tshiab: Qhuav rau 4 mus rau 6 teev kom tshem tawm cov dej seem ntawm lub ntim.
• Rau cov spools raug: Yog hais tias cov filament tau nyob rau hauv ib qho chaw ntub, qhuav rau 8 mus rau 12 teev.
• Rau cov ntaub ntub dej hnyav: yuav tsum muaj 12-teev ziab kom qhuav.
Kauj Ruam 6: Tswj kom muaj cua kom zoo
Ntau lub tshuab ziab khaub ncaws PETG siv yuam-cua ncig los xyuas kom meej txawm tias cua sov. Yog tias koj lub tshuab ziab khaub ncaws muaj kiv cua, xyuas kom tseeb tias nws khiav zoo kom faib cov cua sov kom sib npaug. Qhov no tiv thaiv overheating nyob rau hauv tej qhov chaw thiab xyuas kom meej kom qhuav zoo ib yam.
Kauj Ruam 7: Saib xyuas cov txheej txheem
Thaum ziab, ua ntu zus xyuas cov filament kom paub tseeb tias nws tsis softening lossis deforming. Yog tias koj pom muaj teeb meem, txo qhov kub thiab txias me ntsis thiab ncua sij hawm kom qhuav.
Kauj Ruam 8: Khaws qhuav PETG kom raug
Thaum cov filament qhuav lawm, nws yuav tsum tau muab cia rau hauv lub thawv ntim nrog cov desiccants kom tsis txhob nqus dej noo. Siv lub tshuab nqus tsev ntim cov hnab ntim khoom lossis lub thawv airtight filament tuaj yeem pab tswj nws qhov ziab kom txog thaum siv.

Troubleshooting Common Drying Issues
• Filament tseem luam tawm nrog qhov tsis xws luag: ncua sij hawm kom qhuav los yog tshawb xyuas qhov kub tsis sib xws.
• Filament ua nkig: qhov kub yuav siab dhau; txo nws thiab qhuav rau lub sijhawm ntev dua.
• Filament absorbs noo noo sai sai: Khaws tam sim ntawd rau hauv lub thawv airtight tom qab ziab.

Xaus
Kev teeb tsa koj lub tshuab ziab khaub ncaws PETG kom raug yog qhov tseem ceeb rau kev ua tiav zoo ib yam, zoo 3D luam ntawv. Los ntawm kev ua raws li cov kauj ruam no, koj tuaj yeem tiv thaiv cov teeb meem luam tawm uas tshwm sim los ntawm kev ya raws thiab txhim kho koj cov filament txoj haujlwm. Kev nqis peev sijhawm hauv cov txheej txheem ziab kom zoo ua kom zoo dua adhesion, smoother finishes, thiab muaj zog prints.
