Lub tshuab luam ntawv 3D yog lub tshuab luam ntawv uas tsim cov khoom 3D txheej los ntawm txheej los ntawm cov qauv digital. Qhov 3D tshuab luam ntawv ua haujlwm nyob ntawm qhov kev siv tshuab twg hauv nws: FDM, SLS, SLA, LOM, SGC, PolyJet, DODJet lossis Binding hmoov los ntawm cov nplaum. Qhov nrov tshaj plaws yog FDM luam ntawv tshuab, uas yog siv hauv pheej yig 3D tshuab luam ntawv.
3D luam ntawv yog ib qho ntawm kev hloov kho thev naus laus zis ntawm peb lub sijhawm. Nrog lub tshuab luam ntawv 3D, koj tuaj yeem luam cov khau, khaub ncaws, rooj tog zaum, twj paj nruas, tsheb, khoom noj khoom haus, tsev, thiab txawm tias nyob hauv tib neeg cov leeg thiab cov ntaub so ntswg.
3D tshuab luam ntawv tsim
Lub tshuab luam ntawv 3D nrog FDM luam ntawv tshuab muaj hlau lub cev (thav duab), cov kab ke ua haujlwm kom ruaj ntseg spool ntawm filament, extruder thiab desktop. Ib leeg-extruder 3D tshuab luam ntawv tuaj yeem luam tawm cov khoom tib xim, ntau lub tshuab luam ntawv ntau yam xim. Qhov ntau extruders ib lub tshuab luam ntawv muaj, nws kim dua nws. Hluav taws xob puv thiab cua sov thiab cua txias tshuab tau muab zais hauv qab lub tshuab luam ntawv. Qee cov qauv muaj LCD tso saib cov ntaub ntawv luam tawm tam sim no thiab USB chaw nres nkoj.
Cov neeg siv khoom siv rau 3D luam ntawv
Lub tshuab luam ntawv 3D ib txwm nrog FDM luam ntawv siv cov ntaub ntawv me me lim uas muaj qhov ntev ntawm 1, 75 hli thiab 3 hli ua haujlwm. Cov ntxaij lim dej zoo li no feem ntau ua rau PLA lossis ABS yas, tab sis kuj tseem muaj cov khoom siv sib txuas nrog ntxiv ntawm cov ntoo ua ke, nanopowders, biodegradable particles, phosphorizing pigments thiab lwm yam. Cov xov xov tau muab nyob rau hauv spools uas hnyav ntawm 0.5 kg mus rau 1.5 kg. Spool ntawm polymer filaments tau muab tso rau hauv qhov tshwj xeeb ntawm lub tshuab luam ntawv 3D, thiab qhov kawg ntawm qhov pom tau pub rau hauv lub tshuab extruder.
3D-ua qauv ntawm ib qho khoom
Ua ntej koj tuaj yeem luam 3D ib qho 3D, koj yuav tsum tsim kom muaj digital version ntawm nws hauv qhov qauv 3D qauv. Koj tuaj yeem siv cov qauv npaj uas muaj nyob hauv Is Taws Nem, lossis npaj cov qauv 3D rau kev luam ntawv koj tus kheej. Tus qauv npaj tau thauj mus rau hauv cov kev pabcuam tshwj xeeb rau kev tsim G-code, uas faib cov khoom xa mus rau nyias txheej kab rov tav thiab tsim cov kab ke ntawm cov lus txib uas lub tshuab luam ntawv tuaj yeem nkag siab. Cov khoom tiav yog xa rau luam tawm.
Txheej-txheej-txheej tsim ntawm yam khoom
Lub tshuab luam ntawv 3D nrog FDM luam ntawv thev naus laus zis ua cov khoom hauv lub cev txheej los ntawm txheej, nyem ib ntus nyias nti ntawm cov khoom tawg mus rau hauv kev ua haujlwm. Lub tshuab luam ntawv txav cov extruder raws nraim raws cov qauv digital, yog li cov ntawv luam tawm lub cev tag nrho ua tiav nws cov qauv virtual. Feem ntau, cov tshuab luam ntawv lub tshuab txuas ntxiv, los ntawm qhov cov yas muag muag yog nyem tawm, txav thaum ua haujlwm ntawm lub chaw ua haujlwm ruaj khov, tab sis muaj cov cuab yeej hauv qhov ob extruder thiab kev ua haujlwm platform yog txawb. Cov txheej txheem luam ntawv pib nrog hauv qab txheej, tom qab ntawd lub tshuab luam ntawv siv txheej txheej txuas ntxiv rau sab saum toj ntawm thawj. Melted yas, tau mus rau hauv thaj chaw ua haujlwm, txias thiab hardens sai heev.
3D luam tawm ntawm cov qauv txhawb thiab cov khoom ua tiav
Txhawm rau tiv thaiv qhov khoom los ntawm deforming thaum luam ntawv, 3D tshuab luam ntawv luam tawm cov qauv kev txhawb nqa (aka txhawb cov qauv, kev txhawb nqa qauv). Cov qauv zoo li no tsis yog ib txwm luam tawm, tab sis tsuas yog tias muaj voids lossis kho dua qhov ntawm cov yam ntxwv. Xav tias koj xav sau cov yas puab ntawm cov kav hlau me. Nrog lub hauv paus ntawm txhais ceg, nws tau so ntawm lub desktop, tsis muaj kev txhawb nqa xav tau ntawm no, tab sis rau cov npoo ntawm lub hau, uas zoo li dai rau hauv huab cua, xws li kev txhawb nqa yuav tsim nyog yooj yim. Tom qab luam ntawv, cov qauv kev txhawb nqa tau yooj yim tshem tawm los ntawm txhais tes lossis txiav nrog rab riam los yog riam.
