2023 Cov Khoom Siv Tau Zoo Tshaj 3D Luam Ntawv-TPU

Puas tau xav paub yog vim li cas 3D tshuab luam ntawv tau txais lub zog thiab hloov cov txheej txheem tsim khoom qub?

Yog tias koj sim sau cov laj thawj vim li cas qhov kev hloov pauv no tshwm sim, daim ntawv teev npe yuav pib nrog kev hloov kho.Cov neeg tab tom nrhiav rau tus kheej.Lawv tsis txaus siab rau kev tsim qauv.

Thiab nws yog vim qhov kev hloov pauv ntawm tus cwj pwm ntawm tib neeg thiab lub peev xwm ntawm 3D luam ntawv thev naus laus zis los ua kom tau raws li cov neeg xav tau ntawm tus kheej, los ntawm kev hloov kho, uas nws muaj peev xwm hloov cov txheej txheem kev tsim khoom raws li kev cai.

Flexibility yog qhov zais cia tom qab tib neeg txoj kev tshawb nrhiav tus kheej.Thiab qhov tseeb tias muaj cov khoom siv 3D luam tawm yooj yim muaj nyob rau hauv kev ua lag luam ua rau cov neeg siv txhim kho ntau thiab hloov tau qhov chaw thiab cov qauv ua haujlwm yog qhov muaj txiaj ntsig zoo rau qee cov neeg siv.

3D luam tawm zam thiab 3D luam tawm caj npab yog ib qho piv txwv ntawm cov ntawv thov uas 3D luam ntawv yooj yim yuav tsum tau txais txiaj ntsig.

Rubber 3D luam ntawv yog ib qho chaw uas tseem nyob rau hauv kev tshawb fawb thiab tseem tsis tau tsim.Tab sis tam sim no, peb tsis muaj roj hmab 3D luam ntawv thev naus laus zis, txog thaum cov roj hmab tuaj yeem luam tau tag, peb yuav tau tswj nrog lwm txoj hauv kev.

Thiab raws li kev tshawb fawb qhov ze tshaj plaws rau cov roj hmab uas poob rau hauv hu ua Thermoplastic Elastomers.Muaj plaub yam sib txawv ntawm cov ntaub ntawv hloov tau yooj yim uas peb yuav los saib qhov tob hauv kab lus no.

Cov ntaub ntawv hloov pauv 3D luam ntawv no muaj npe TPU, TPC, TPA, thiab Soft PLA.Peb yuav pib los ntawm kev muab cov lus qhia luv luv rau koj txog Flexible 3D luam ntawv cov khoom siv dav dav.

Dab tsi yog Filament Flexible Filament?

Xaiv cov filaments saj zawg zog rau koj qhov project 3D luam ntawv tom ntej no yuav qhib lub ntiaj teb sib txawv rau koj cov ntawv luam tawm.

Tsis tsuas yog koj tuaj yeem luam tawm ntau yam khoom sib txawv nrog koj cov flex filament, tab sis kuj yog tias koj muaj ob lossis ntau lub taub hau extruder uas muaj lub tshuab luam ntawv, koj tuaj yeem luam tawm cov khoom zoo nkauj siv cov khoom siv no.

Cov khoom siv thiab cov qauv ua haujlwm xws li bespoke flip flops, kev ntxhov siab pob taub hau, lossis tsuas yog vibration dampeners tuaj yeem luam tawm siv koj lub tshuab luam ntawv.

Yog tias koj txiav txim siab los ua Flexi filament ib feem ntawm kev luam koj cov khoom, koj yuav tsum ua tiav hauv kev ua kom koj cov kev xav ze tshaj qhov tseeb.

Nrog ntau txoj kev xaiv muaj nyob rau hauv daim teb no, nws yuav nyuaj rau xav txog lub sijhawm uas twb tau dhau los hauv kev lag luam 3D nrog rau qhov tsis muaj cov khoom luam ntawv no.

Rau cov neeg siv, luam ntawv nrog hloov pauv filaments, rov qab los, yog qhov mob hauv lawv lub nroog Yeiuxalees.Qhov mob yog vim muaj ntau yam uas tau spiraled ib ncig ntawm qhov tseeb tias cov ntaub ntawv no yog mos heev.

Qhov softness ntawm cov khoom siv 3D luam ntawv yooj yim ua rau lawv muaj kev pheej hmoo los luam tawm nrog ib lub tshuab luam ntawv xwb, es tsis txhob, koj xav tau ib yam dab tsi tiag tiag.

Feem ntau ntawm cov tshuab luam ntawv rov qab tau ntsib teeb meem ntawm kev thawb txoj hlua, yog li thaum twg koj thawb ib yam dab tsi ntawm lub sijhawm ntawd yam tsis muaj kev nruj ntawm lub nozzle, nws yuav khoov, twist, thiab tawm tsam nws.

Txhua tus neeg uas paub txog kev nchuav xov los ntawm ib rab koob rau xaws txhua hom ntaub tuaj yeem cuam tshuam txog qhov tshwm sim no.

Sib nrug los ntawm qhov teeb meem ntawm cov nyhuv thawb, kev tsim cov filaments softer xws li TPE yog ib txoj haujlwm zoo heev, tshwj xeeb tshaj yog nrog kev ua siab ntev.

Yog tias koj xav txog kev ua siab ntev tsis zoo thiab pib tsim khoom, muaj feem ntau ntawm cov filament uas koj tau tsim tawm yuav tau ua kom tsis zoo, kev sib tsoo, thiab txheej txheem extrusion.

Tab sis txhua yam tau hloov pauv, tam sim no, muaj ntau yam ntawm cov mos mos filaments, qee qhov ntawm lawv txawm tias muaj zog elasticity thiab sib txawv ntawm cov softness.Mos PLA, TPU, thiab TPE yog qee qhov piv txwv.

Ntug Hardness

Qhov no yog ib qho kev ntsuas uas koj yuav pom nrog cov tuam txhab filament hais txog nrog rau lub npe ntawm lawv cov khoom siv 3D luam ntawv.

Shore Hardness txhais tau tias yog qhov ntsuas ntawm kev tiv thaiv txhua yam khoom muaj rau indentation.

Qhov ntsuas no tau tsim nyob rau yav dhau los thaum tib neeg tsis muaj kev siv thaum tham txog qhov nyuaj ntawm cov khoom siv.

Yog li, ua ntej Shore hardness tau tsim, tib neeg yuav tsum tau siv lawv cov kev paub dhau los rau lwm tus los piav qhia qhov nyuaj ntawm txhua yam khoom uas lawv tau sim ua, tsis yog hais txog tus lej.

Qhov ntsuas no dhau los ua ib qho tseem ceeb thaum xav txog cov khoom siv pwm twg los xaiv rau kev tsim khoom ntawm ib feem ntawm cov qauv ua haujlwm.

Yog li, piv txwv li, thaum koj xav xaiv ntawm ob lub roj hmab rau kev ua cov pwm ntawm plaster sawv ballerina, Shore hardness yuav qhia rau koj kom muaj cov roj hmab ntawm luv luv hardness 70 A yog tsawg dua cov roj hmab nrog ntug hardness ntawm 30 A.

Feem ntau thaum ua haujlwm nrog filaments koj yuav paub tias qhov pom zoo shore hardness ntawm cov khoom siv tau yooj yim nyob qhov twg ntawm 100A txog 75A.

Qhov twg, pom tseeb, qhov hloov pauv 3D luam ntawv cov khoom siv uas muaj ntug hiav txwv hardness ntawm 100A yuav nyuaj dua li qhov muaj 75A.

Yuav xav li cas thaum Yuav Ib Lub Flexible Filament?

Muaj ntau yam yuav tsum tau xav txog thaum yuav ib qho filament, tsis yog hloov tau yooj yim.

Koj yuav tsum pib los ntawm qhov chaw nruab nrab uas yog qhov tseem ceeb tshaj plaws rau koj kom muaj, ib yam dab tsi zoo li cov khoom siv zoo uas yuav ua rau muaj qhov zoo ntawm cov qauv ua haujlwm.

Tom qab ntawd koj yuav tsum xav txog kev ntseeg siab hauv cov khoom siv xws li cov khoom siv uas koj siv ib zaug rau 3D luam ntawv, yuav tsum muaj tsis tu ncua, txwv tsis pub, koj yuav xaus rau kev siv cov khoom siv tsawg kawg ntawm 3D luam ntawv.

Tom qab tau xav txog cov xwm txheej no, koj yuav tsum xav txog qhov siab elasticity, ntau yam xim.Rau, tsis yog txhua qhov hloov pauv 3D luam ntawv yuav muaj nyob rau hauv cov xim uas koj xav yuav nws hauv.

Tom qab tau txiav txim siab tag nrho cov xwm txheej no koj tuaj yeem xav txog lub tuam txhab kev pabcuam cov neeg siv khoom thiab tus nqi rau hauv tus account piv rau lwm lub tuam txhab hauv kev ua lag luam.

Tam sim no peb yuav sau qee yam ntawm cov ntaub ntawv uas koj tuaj yeem xaiv rau luam tawm qhov hloov tau yooj yim lossis cov qauv ua haujlwm.
