Dab tsi tsim nta Ua kom sov phaj haum rau 3D tshuab luam ntawv Tsim Platforms?

Thawj cov khaubncaws sab nraud povtseg ntawm 3D luam ntawv yuav tsum tau muab cua sov sib npaug los ntawm 3D tshuab luam ntawv txaj kom txo qis warping thiab pab cov ntawv luam tawm. Cov phaj cua sov yog ib qho tseem ceeb, sib txuas cov thermal kev ua tau zoo nrog cov neeg kho tshuab raug thiab chemistry nto.

Cov kev cai tseem ceeb rau lub tshuab luam ntawv 3D tsim phaj cua sov tsim
Txhawm rau muab kev ua tau zoo ntawm kev luam ntawv, lub tshuab luam ntawv 3D tsim cov phaj cua sov yuav tsum tau ua kom tau raws li qhov xav tau tshwj xeeb. Lawv suav nrog:

1. Txawm cua sov
Nws yog ib qho tseem ceeb uas yuav tsum muaj cov cua sov sib xws thoob plaws tag nrho cov phaj tsim kom txo qis qhov kub thiab txias uas tuaj yeem ua rau tsis zoo ua ntej - txheej adhesion thiab warping. Aluminium daim hlau yog dav siv vim muaj thermal conductivity uas muab kev faib tawm ntawm cov cua sov. PCB-style heaters lossis silicone heater lev feem ntau yog siv rau hauv cov tshuab no rau lawv qhov yooj yim thiab homogeneity. Lawv tso cai rau tag nrho cov saum npoo yuav tsum tau nce mus rau qhov xav tau qhov kub thiab txias yam tsis muaj cua sov hauv zos.

Lub txaj kub feem ntau hloov pauv raws li cov khoom koj luam tawm. Piv txwv li:

PLA: 60 degree

ABS: 100-110 ° C

Cov ntaub ntawv kub: max . 150 degree

2. Flattness
Lub flatness ntawm lub tshuab luam ntawv nto kuj yog ib qho tseem ceeb. Ib qho chaw tiaj tus heev yog xav tau los tswj kom tsis tu ncua nozzle tshem tawm thoob plaws hauv cheeb tsam tsim, uas yog qhov tseem ceeb rau kev luam ntawv zoo. Feem ntau cov ntawv luam tawm yuav tsum tiaj tus nyob rau hauv ob peb kaum ntawm microns kom tsis txhob muaj qhov sib txawv ntawm qhov sib txawv thiab kom paub tseeb tias cov khaubncaws sab nraud povtseg zoo ua ke.

3D tshuab luam ntawv tsim daim hlau feem ntau yog txhuas, uas nyob qis qis thiab tseem ua kom sov zoo. Qee cov iav phaj zoo kawg nkaus tsis tau siv sijhawm ntev dua los ua kom sov vim tias lawv cov cua sov ntau ntxiv. Kev xaiv cov ntaub ntawv cuam tshuam rau thermal efficiency thiab mechanical kev ua tau zoo.

3. Txheej txheej
Cov txheej txheej saum npoo yog ib qho tseem ceeb kom ntseeg tau tias kev ua tau zoo thaum luam ntawv thiab yooj yim tso tawm ntawm qhov chaw thaum luam ntawv tiav. Cov txheej txheem muaj xws li PEI (Polyetherimide), BuildTak, lossis kev cai textured tiav. Cov coatings no muab cov adhesion zoo thaum lub txaj yog rhuab, tab sis yooj yim dua los tso cov khoom luam tawm thaum txias, yog li txo qis qhov tshwm sim ntawm kev luam ntawv tsis ua hauj lwm lossis warping.

Cov ntaub ntawv rau 3D tshuab luam ntawv tsim daim hlau
Aluminium yog qhov kev xaiv nrov rau 3D tshuab luam ntawv tsim daim hlau vim nws qhov sib xyaw zoo ntawm thermal conductivity thiab flatness. Nws ua kom sov sai sai thiab ua kom tsis sib xws ntawm qhov chaw. Cov iav iav, txawm li cas los xij, zoo dua ntawm kev muab cov tiaj tiaj tab sis muaj qhov ntsuas kub qeeb qeeb thiab tsis tshua muaj txiaj ntsig rau cua sov ceev.

Tsis tsuas yog cov khoom siv yooj yim xwb, tab sis kuj tseem yog txheej txheej ntawm qhov chaw tseem ceeb heev los txhim kho kev ua tau zoo. Cov txheej txheej yuav tsum tsim nyog nrog cov cua sov thiab yuav tsum tau ua kom dhau lub thermal cycling ntawm lub tshuab luam ntawv 3D lub sij hawm tsis muaj degradation.

3D tshuab luam ntawv lub txaj Rhaub Rhaub Xaiv Daim Ntawv Teev Npe
Cov Cuab Yeej Siv Hluav Taws Xob: Nco ntsoov tias lub tshuab cua sov faib qhov ntsuas kub sib npaug thoob plaws qhov chaw.

Flatness: Xyuas kom meej tias qhov chaw luam ntawv yog tiaj tus nyob rau hauv kaum ntawm microns los muab cov nozzle txaus tshem tawm.

Cov ntaub ntawv: Xaiv cov aluminium (siab dua thermal conductivity) los yog iav (zoo meej tiaj tus) raws li kev siv.

Txheej Txheej: Xaiv qhov tsim nyog adhesion- txhawb cov txheej txheem xws li PEI lossis BuildTak rau qhov zoo tshaj plaws tso tawm tom qab luam ntawv.

Qhov kub thiab txias: Lub tshuab cua sov yuav tsum muaj peev xwm ua tau raws li qhov xav tau kub (60℃rau PLA, 100 txog 110℃rau ABS, mus txog 150℃rau cov khoom kub).

Heater Bonding: Xyuas kom lub rhaub muaj kev sib raug zoo rau lub phaj kom tsis txhob delamination thiab ua kom kub zoo dua.

Abstract
Kev tsim ntawm lub tshuab luam ntawv 3D tsim lub phaj rhaub suav nrog ntau yam tseem ceeb - homogeneous tsis kub cua sov, siab flatness, thiab cov txheej txheej saum npoo tau sib haum nrog adhesion - uas muab cov adhesion zoo ntawm thawj txheej luam tawm thaum txo qis warpage. Kev xaiv ntawm cov khoom siv phaj, txheej txheej thiab cua sov txheej txheem muaj kev cuam tshuam zoo rau kev ua tiav ntawm 3D luam ntawv txheej txheem. Raws li 3D luam ntawv thev naus laus zis txuas ntxiv mus, qhov kev xav tau rau kev cai - tsim cov cua sov kev daws teeb meem los ua kom haum rau cov kev xav tau ntawm kev tsim cov thev naus laus zis yuav yog qhov tseem ceeb.
