Tib neeg yuav xav tias thaum peb muaj lub tshuab luam ntawv 3D, peb yog txhua yam.Peb tuaj yeem luam txhua yam peb xav tau hauv txoj kev yooj yim.Txawm li cas los xij, muaj ntau yam laj thawj uas yuav cuam tshuam qhov kev ntxhib los mos ntawm cov ntawv luam tawm.Yog li yuav ua li cas kom du cov khoom siv FDM 3D feem ntau siv - PLA luam tawm?Hauv tsab xov xwm no, peb yuav muab qee cov lus qhia txog cov txiaj ntsig tsis zoo uas tshwm sim vim yog vim li cas ntawm cov tshuab luam ntawv 3D.
Wavy Qauv
Cov qauv wavy tshwm vim yog lub tshuab luam ntawv 3D vibrations lossis wobbling.Koj yuav pom cov qauv no thaum extruder ntawm lub tshuab luam ntawv ua rau kev hloov pauv sai, xws li nyob ze ntawm lub kaum ntse ntse.Los yog yog tias lub tshuab luam ntawv 3D muaj qhov xoob, nws tuaj yeem ua rau muaj kev vibration.Tsis tas li ntawd, yog tias qhov ceev heev rau koj lub tshuab luam ntawv los tuav, kev co lossis wobbling tshwm sim.
Xyuas kom koj ceev cov bolts thiab siv ntawm lub tshuab luam ntawv 3D thiab hloov cov uas hnav tawm.Muab lub tshuab luam ntawv tso rau ntawm lub rooj ruaj khov lossis qhov chaw thiab xyuas seb cov bearings thiab lwm yam txav ntawm lub tshuab luam ntawv ua haujlwm zoo yam tsis muaj jerk.Thiab koj yuav tsum tau lubricate cov khoom no yog tias muaj.Thaum koj tau daws qhov teeb meem no, nws yuav tsum tso tseg qhov tsis zoo ntawm cov kab tsis sib luag thiab wavy hauv koj cov ntawv luam tawm uas ua rau cov phab ntsa tsis du.
Tus nqi Extrusion tsis raug
Ib qho tseem ceeb tshaj plaws uas txiav txim siab qhov tseeb thiab qhov zoo ntawm kev luam ntawv yog tus nqi extrusion.Tshaj extrusion thiab nyob rau hauv extrusion tuaj yeem ua rau tsis zoo nkauj.
Qhov xwm txheej dhau ntawm extrusion tshwm sim thaum lub tshuab luam ntawv extrudes PLA ntau dua li qhov xav tau.Txhua txheej zoo li pom tseeb ntawm qhov chaw ntawm daim ntawv luam tawm, uas qhia txog qhov tsis xwm yeem.Peb hais kom kho tus nqi extrusion ntawm kev luam ntawv software thiab tseem them nyiaj rau qhov kub extrusion.
Qhov no nyob rau hauv qhov xwm txheej extrusion tshwm sim thaum tus nqi extrusion qis dua qhov xav tau.PLA filaments tsis txaus thaum luam ntawv yuav ua rau qhov chaw tsis zoo thiab qhov sib txawv ntawm cov khaubncaws sab nraud povtseg.Peb pom zoo kom ib txoj kab uas hla filaments los ntawm kev siv 3D tshuab luam ntawv software los kho cov extrusion multiplier.
Filaments Overheating
Qhov kub thiab txias tus nqi rau PLA filaments yog ob yam tseem ceeb.Qhov sib npaug ntawm ob yam no yuav muab cov ntawv luam tawm nrog kev ua tiav zoo.Yog tias tsis muaj qhov txias txias, nws yuav ua rau lub sijhawm teem sijhawm.
Txoj hauv kev kom tsis txhob overheating yog kom txo qhov txias txias, ua kom qhov txias txias, lossis txo qhov nrawm nrawm kom muab sijhawm rau kho.Khaws tswj cov kev txwv no kom txog thaum koj pom cov xwm txheej zoo meej rau kev ua tiav.
Blobs thiab Zits
Thaum luam ntawv, yog tias koj tab tom sim koom nrog ob qhov kawg ntawm cov qauv yas ua ke nws pom tias nyuaj ua nws yam tsis muaj kab.Thaum lub extrusion pib thiab nres, nws tsim irregular spillage ntawm lub hlws ris.Cov no hu ua blobs thiab zits.Qhov xwm txheej no ua rau lub ntsej muag zoo meej ntawm cov ntawv luam tawm.Peb hais kom kho qhov retract los yog swb nqis hauv 3D tshuab luam ntawv software.Yog hais tias qhov chaw retraction tsis raug, cov yas ntau dhau yuav raug tshem tawm ntawm lub tshuab luam ntawv.
