Puas tau xav paub yog vim li cas yog 3D tshuab luam ntawv thev naus laus zis tau muaj zog thiab hloov cov qub teev ua ke technologies?
Yog tias koj sim ua cov laj thawj uas yog qhov kev hloov pauv no tshwm sim, cov npe yuav pib customization. Cov neeg tab tom nrhiav rau tus kheej. Lawv tsis tshua nyiam ua qauv txheem.
Thiab nws yog vim tias qhov hloov no hauv kev coj cwj pwm ntawm cov neeg thiab lub peev xwm ntawm kev siv tshuab 3D kev xav tau, los ntawm kev hloov kho ntawm tus kheej, los ntawm kev hloov kho ntawm kev lig kev cai txhim kho thev naus laus zis.
Yooj yooj yim yog qhov zais zais tom qab tib neeg tshawb xyuas tus kheej. Thiab qhov tseeb hais tias muaj hloov cov ntaub ntawv 3D luam tau ntau thiab ntau qhov kev ua haujlwm yog qhov chaw ntawm cov neeg siv ntshiab rau qee cov neeg siv.
3D luam tawm kev zam thiab 3D luam tawm cov caj npab prosthetic yog ib qho piv txwv ntawm cov ntawv thov uas muaj kev txaus siab 3D kev luam ntawv.
Roj Hmab 3D Luam Ntawv yog thaj chaw uas tseem tshawb nrhiav thiab tsis tau tsim kho. Tab sis tam sim no, peb tsis muaj roj hmab 3D tshuab luam ntawv tshuab ua tiav luam tawm tag nrho, peb yuav tau tswj hwm nrog lwm txoj kev xaiv.
Thiab raws li kev tshawb fawb cov kev xaiv ze tshaj plaws rau cov roj hmab uas poob rau hauv yog hu ua thermoplastic elastomers. Muaj plaub lub hom sib txawv ntawm cov khoom siv hloov tau uas peb yuav mus saib hauv qhov tob hauv kab lus no.
Cov ntaub ntawv luam tawm 3D luam tau muaj npe TPU, TPC, TPA, thiab Mos Pla. Peb yuav pib los ntawm kev muab luv luv rau koj txog kev hloov kho 3D luam tawm cov khoom siv dav dav.
Dab tsi yog qhov yoog tau flexament flexent dab tsi?
Xaiv cov filaments saj zawg zog rau koj txoj haujlwm 3D txuas ntxiv yuav qhib lub ntiaj teb ntawm cov kev sib txawv ntawm koj cov luam tawm.
Tsis yog koj puas tuaj yeem luam tawm ntau yam ntawm cov khoom sib txawv nrog koj cov extruder ntau, koj tuaj yeem sau cov khoom zoo nkauj uas siv cov khoom siv no.
Qhov chaw thiab cov qauv ua haujlwm zoo xws li bespoke flip flops, lossis tsuas yog kev co damration dampeners tuaj yeem luam tawm siv koj lub tshuab luam ntawv.
Yog tias koj tau txiav txim siab ua Flexie flexi flex
Nrog ntau yam kev xaiv muaj nyob rau hauv daim teb no, nws yuav nyuaj rau xav txog lub sijhawm uas twb tau dhau mus nyob hauv cov ntawv tsis muaj no.
Rau cov neeg siv, luam ntawv nrog cov ua kom tiav cov filaments, rov qab ces, yog qhov mob hauv lawv lub nroog Yeiuxalees. Qhov mob tau vim muaj ntau yam uas tau muab kauv ib ncig ntawm ib qho tseeb uas cov ntaub ntawv no yog qhov muag heev.
Qhov muag ntawm lub tshuab luam ntawv 3D luam tawm ua rau lawv pheej hmoo tau luam tawm nrog tsuas yog muaj luam ntawv, koj xav tau ib yam dab tsi tiag tiag txhim khu kev qha.
Feem ntau ntawm cov luam ntawv rov qab ces ntsib teeb meem ntawm txoj hlua hlua ntawm lub sijhawm ntawd yam tsis muaj ib yam dab tsi nyob rau lub sij hawm nonzzle, nws yuav khoov, ntswj, thiab tawm tsam nws.
Txhua tus uas paub nrog pouring xov los ntawm rab koob rau xaws rau txhua daim ntaub tuaj yeem cuam tshuam nrog qhov tshwm sim no.
Sib nrug los ntawm cov teeb meem ntawm cov nyhuv thawb, ua lag luam softer filaments xws li TPE yog ib txoj haujlwm phem heev, tshwj xeeb nrog kev thev taus zoo heev.
Yog tias koj xav txog kev ua siab phem thiab pib tsim khoom, muaj kev tsim khoom, muaj cov tsim khoom siv yuav muaj cov xwm txheej tsis zoo, jamming, thiab cov txheej txheem extrusion.
Tab sis txhua yam tau hloov, tam sim no, muaj ntau yam ntawm cov filam muag muag, qee tus txawm nrog Elastic Paus thiab sib txawv ntawm cov kev muag khoom. Mos Pla, TPu, thiab TPE yog qee qhov piv txwv.
Ntug dej hardness
Nov yog kev ntsuas uas koj yuav pom nrog cov kws ua lag luam hais txog cov npe ntawm lawv cov khoom siv luam ntawv 3D luam.
Ntug dej Hardness yog txhais raws li kev ntsuas ntawm kev tiv thaiv txhua cov khoom muaj rau indentation.
Cov nplai no tau tsim yav dhau los thaum tib neeg tsis muaj kev siv thaum tham txog lub hardness ntawm ib qho khoom siv.
Yog li, ua ntej ntug dej hardness tau tsim, tib neeg yuav tsum tau siv lawv cov kev paub rau lwm tus kom tau sim lub zog ntawm cov khoom uas lawv tau sim rau, tsis yog hais txog tus lej.
Cov nplai no dhau los ua ib qho tseem ceeb thaum txiav txim siab cov khoom siv pwm los xaiv rau kev tsim khoom ntawm ib feem ntawm kev ua haujlwm ua haujlwm.
Yog li piv txwv li, thaum koj xav xaiv ntawm ob zaug ntawm plaster sawv ballerina, ntug dej lub hardness 70 A yog qhov tsawg dua muaj txiaj ntsig zoo dua li cov roj hmab nrog ntug dej hardness ntawm 30 A.
Feem ntau thaum cuam tshuam nrog cov filaments koj yuav paub tias cov kev pom zoo uas muaj kev pom zoo ntawm cov khoom siv tau yooj yim nyob txhua qhov chaw ntawm 100a rau 75a.
Qhov twg, pom tseeb, hloov kho 3D luam tawm uas muaj chaw nkaum hardness ntawm 100a yuav nyuaj dua li uas muaj 75A.
Dab tsi los xav txog thaum yuav ib qho kev yuav khoom siv tau yooj ywm?
Muaj ntau yam los txiav txim siab thaum yuav ib yam lus dab tsi, tsis yog qhov hloov tau.
Koj yuav tsum tau pib los ntawm qhov chaw taw tes uas yog qhov tseem ceeb tshaj plaws rau koj kom muaj, ib yam dab tsi zoo li cov khoom zoo uas tau zoo uas yuav ua rau muaj kev ua haujlwm zoo.
Tom qab ntawd koj yuav tsum xav txog kev ntseeg tau rau hauv cov khoom siv uas koj siv rau 3D luam, yuav tsum tsis tu ncua, koj yuav xaus rau qhov kawg ntawm 3D luam ntawv.
Tom qab tau xav txog cov yam ntxwv no, koj yuav tsum xav txog siab elasticity, muaj ntau yam xim. Rau, tsis yog txhua txhua hloov cov ntaub ntawv yees duab 3D yuav muaj nyob hauv cov xim uas koj xav yuav nws hauv.
Tom qab tau txiav txim siab tag nrho cov ntsiab lus koj tuaj yeem xav txog lub tuam txhab cov kev pabcuam cov neeg siv khoom thiab tus nqi rau lwm cov tuam txhab hauv khw.
Tam sim no peb yuav teev tseg qee cov ntaub ntawv uas koj tuaj yeem xaiv rau kev luam tawm ib feem lossis cov qauv ua haujlwm.
Daim ntawv teev cov ntawv luam tawm 3D cov luam ntawv
Tag nrho cov ntawv hauv qab no muaj qee cov yam ntxwv yooj yim xws li lawv txhua tus hloov tau thiab muag. Cov ntaub ntawv muaj kev nkees zoo heev thiab cov hluav taws xob zoo.
Lawv muaj kev ua kom zoo nkauj damming thiab cuam tshuam lub zog. Cov ntaub ntawv no ua rau tsis kam rau cov tshuaj thiab huab cua, lawv muaj lub kua muag zoo thiab ua kom tsis taus.
Tag nrho cov ntawm lawv tau rov ua dua tshiab thiab muaj kev poob siab-nqus tau muaj peev xwm.
Tshuab luam ntawv yuav tau ua ntej rau luam ntawv nrog cov khoom siv luam tawm tshiab
Muaj qee cov qauv kev ntseeg los teeb tsa koj lub tshuab luam ntawv ua ntej luam ntawv nrog cov ntaub ntawv no.
