6. Rooj Tswj Xyuas: Lub hlwb ntawm lub tshuab luam ntawv uas khiav cov firmware thiab yog lub luag haujlwm rau kev tswj hwm txhua yam khoom kom lawv ua haujlwm tau zoo.
Hom Tshuab Luam Ntawv 3D
Cov tshuab luam ntawv 3D muaj ntau hom sib txawv, tab sis feem ntau yog:
1. Fused Deposition Modeling (FDM): Siv cov thermoplastic filaments uas yaj lawm uas raug tso rau txheej dhau txheej. Piv txwv ntawm cov ntaub ntawv siv feem ntau yog PLA thiab ABS.
2. Stereolithography (SLA): Siv cov kua roj uas ua kom cov duab khov kho ua ib txheej dhau ib txheej siv lub teeb UV. Feem ntau yuav tsim tau cov duab zoo dua tab sis yuav tsum tau saib xyuas ntau dua.
3. Kev Siv Laser Sintering (SLS): Siv cov hmoov uas raug cua sov thiab sintered txheej los ntawm lub teeb laser. Lub tshuab no feem ntau siv rau cov khoom siv hlau thiab tsim cov pwm muaj zog heev.
Cov Txheej Txheem Luam Ntawv 3D
Yuav kom nkag siab txog seb lub tshuab luam ntawv 3D ua haujlwm li cas, cia peb mus saib cov kauj ruam dav dav.
1. Tsim Qauv 3D
Kauj ruam thawj zaug yog tsim ib daim qauv 3D ntawm yam khoom uas koj xav luam tawm. Muaj ntau cov kev pab cuam CAD software muaj rau qhov no, xws li Tinkercad, Fusion 360, lossis Blender. Cov qauv tiav lawm feem ntau raug khaws cia rau hauv STL (Standard Triangle Language) lossis OBJ cov ntaub ntawv hom ntawv.
2. Txiav
Thaum koj muaj ib daim qauv 3D lawm, kauj ruam tom ntej yog npaj nws rau kev luam ntawv siv software slicer. Qhov program no yuav siv daim qauv 3D thiab faib nws ua ntau txheej, uas tom qab ntawd txhais ua cov lus qhia luam ntawv (G-code) uas lub tshuab luam ntawv 3D tuaj yeem nkag siab. Qee cov software slicer nrov suav nrog Cura, PrusaSlicer, thiab Simplify3D.
3. Kev Teeb tsa Lub Tshuab Luam Ntawv
Ua ntej pib luam ntawv, peb yuav tsum xyuas kom meej tias txhua qhov chaw teeb tsa ntawm lub tshuab luam ntawv raug. Qhov no suav nrog kev xyuas kom meej tias lub tshuab luam ntawv tau teeb tsa kom tiaj tus (kho qhov deb ntawm lub nozzle thiab lub platform), ntxig lub filament kom raug, thiab txhua qhov kev sib txuas tau txuas nrog.
4. Pib Luam Ntawv
Thaum txhua yam npaj txhij lawm, peb tuaj yeem pib ua cov txheej txheem luam ntawv. Lub tshuab luam ntawv yuav nyeem cov ntaub ntawv G-code thiab pib luam cov khoom txheej los ntawm txheej. Thaum lub sijhawm no, lub tshuab extruder yuav ua kom cov filament sov kom txog thaum nws yaj thiab tom qab ntawd nws tawm los ntawm lub nozzle ntawm qhov chaw teev tseg los ntawm G-code.
5. Tom qab ua tiav
Thaum luam ntawv tiav lawm, tej zaum yuav tsum muaj ntau kauj ruam tom qab ua tiav, nyob ntawm hom tshuab luam ntawv thiab cov khoom siv. Nrog rau cov tshuab luam ntawv FDM, feem ntau koj tsuas yog yuav tsum tshem tawm cov khoom ntawm lub platform thiab tshem tawm cov qauv txhawb nqa. Nrog rau cov tshuab luam ntawv resin (SLA), feem ntau koj yuav tsum ntxuav cov khoom hauv isopropyl cawv thiab tom qab ntawd kho nws nrog lub teeb UV.
