Puas tau xav tias vim li cas cov thev naus laus zis luam ntawv 3D thiaj li muaj zog thiab hloov cov thev naus laus zis tsim khoom qub?
Yog 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 kom haum rau koj tus kheej. Tib neeg tab tom nrhiav kev hloov kho kom haum rau koj tus kheej. Lawv tsis tshua xav txog kev ua kom raws li tus 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 tib neeg xav tau kev kho kom haum, los ntawm kev hloov kho, uas nws muaj peev xwm hloov cov thev naus laus zis tsim khoom raws li kev cai ib txwm muaj.
Kev ywj pheej yog ib qho zais cia tom qab tib neeg nrhiav kev ua tus kheej. Thiab qhov tseeb tias muaj cov khoom siv luam ntawv 3D ywj pheej muaj nyob rau hauv kev ua lag luam uas ua rau cov neeg siv tsim cov khoom seem thiab cov qauv ua haujlwm tau zoo dua yog qhov chaw zoo siab rau qee tus neeg siv.
Zam 3D luam tawm thiab caj npab cuav luam tawm 3D yog ib qho piv txwv ntawm cov ntawv thov uas yuav tsum tau txais kev txaus siab rau qhov yooj ywm ntawm kev luam tawm 3D.
Kev luam ntawv 3D roj hmab yog ib qho chaw uas tseem tab tom tshawb nrhiav thiab tseem tsis tau tsim kho. Tab sis tam sim no, peb tseem tsis tau muaj cov thev naus laus zis luam ntawv 3D roj hmab, kom txog thaum roj hmab luam tawm tau tag nrho, peb yuav tsum tswj hwm nrog lwm txoj hauv kev.
Thiab raws li kev tshawb fawb, cov lwm txoj hauv kev zoo tshaj plaws rau roj hmab uas poob rau hauv yog hu ua Thermoplastic Elastomers. Muaj plaub hom khoom siv hloov pauv tau uas peb yuav los saib tob hauv tsab xov xwm no.
Cov ntaub ntawv luam tawm 3D uas yoog tau no hu ua TPU, TPC, TPA, thiab Soft PLA. Peb yuav pib los ntawm kev qhia luv luv txog cov ntaub ntawv luam tawm 3D uas yoog tau feem ntau.
Dab tsi yog Filament Flexible tshaj plaws?
Kev xaiv cov filaments uas yooj ywm rau koj qhov project 3D printing tom ntej yuav qhib lub ntiaj teb ntawm ntau yam kev xaiv rau koj cov prints.
Tsis yog koj tuaj yeem luam tawm ntau yam khoom sib txawv nrog koj cov flex filament xwb, tab sis kuj yog tias koj muaj lub tshuab luam ntawv dual lossis ntau lub taub hau extruder, koj tuaj yeem luam tawm cov khoom zoo nkauj siv cov khoom siv no.
Cov khoom thiab cov qauv ua haujlwm xws li cov khau khiab ua raws li tus kheej, lub taub hau pob siab, lossis tsuas yog cov khoom txo kev co tuaj yeem luam tawm siv koj lub tshuab luam ntawv.
Yog tias koj txiav txim siab siv Flexi filament los luam koj cov khoom, koj yuav ua tiav hauv kev ua kom koj lub tswv yim ze rau qhov tseeb.
Muaj ntau txoj kev xaiv muaj niaj hnub no hauv daim teb no, nws yuav nyuaj rau xav txog lub sijhawm uas twb tau dhau los hauv daim teb ntawm 3D luam ntawv nrog qhov tsis muaj cov ntaub ntawv luam ntawv no.
Rau cov neeg siv, kev luam ntawv nrog cov filaments uas yoog tau, rov qab rau lub sijhawm ntawd, yog qhov mob hauv lawv lub pob tw. Qhov mob yog vim muaj ntau yam uas tau sib xyaw ua ke ib qho tseeb tias cov ntaub ntawv no mos heev.
Qhov mos mos ntawm cov khoom siv luam ntawv 3D uas yooj ywm ua rau lawv muaj kev pheej hmoo kom luam tawm nrog txhua lub tshuab luam ntawv, es tsis txhob, koj xav tau qee yam uas ntseeg tau tiag tiag.
Feem ntau ntawm cov tshuab luam ntawv rov qab rau lub sijhawm ntawd ntsib teeb meem ntawm kev thawb cov hlua, yog li thaum twg koj thawb ib yam dab tsi thaum lub sijhawm ntawd yam tsis muaj kev nruj los ntawm lub nozzle, nws yuav khoov, ntswj, thiab tawm tsam nws.
Txhua tus neeg uas paub txog kev nchuav xov los ntawm rab koob rau xaws txhua yam ntaub tuaj yeem cuam tshuam nrog qhov xwm txheej no.
Sib nrug ntawm qhov teeb meem ntawm qhov cuam tshuam thawb, kev tsim cov filaments softer xws li TPE yog ib txoj haujlwm nyuaj heev, tshwj xeeb tshaj yog nrog kev kam rau siab zoo.
Yog tias koj xav txog kev ua siab ntev tsis zoo thiab pib tsim khoom, muaj feem ntau uas cov filament uas koj tau tsim yuav tsum tau dhau los ua qhov tsis zoo, jamming, thiab extrusion txheej txheem.
Tab sis tej yam tau hloov pauv lawm, tam sim no, muaj ntau yam filaments mos, qee qhov ntawm lawv txawm tias muaj cov khoom elastic thiab ntau qib ntawm kev mos. Soft PLA, TPU, thiab TPE yog qee qhov piv txwv.
Ntug dej Hardness
Qhov no yog ib qho qauv uas koj yuav pom nrog cov tuam txhab tsim filament hais txog nrog rau lub npe ntawm lawv cov khoom siv luam ntawv 3D.
Shore Hardness yog txhais tias yog qhov ntsuas ntawm kev tiv taus txhua yam khoom siv rau kev nkag mus.
Qhov nplai no tau tsim los yav dhau los thaum tib neeg tsis muaj qhov siv thaum tham txog qhov nyuaj ntawm cov khoom siv.
Yog li, ua ntej Shore hardness tau tsim, tib neeg yuav tsum siv lawv cov kev paub rau lwm tus los piav qhia txog qhov nyuaj ntawm cov khoom siv uas lawv tau sim, es tsis txhob hais txog tus lej.
Qhov nplai 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.
Piv txwv li, thaum koj xav xaiv ntawm ob lub roj hmab rau kev ua pwm ntawm plaster sawv ballerina, Shore hardness yuav qhia rau koj tias roj hmab ntawm luv luv hardness 70 A tsis muaj txiaj ntsig ntau dua li roj hmab nrog ntug dej hardness ntawm 30 A.
Feem ntau thaum koj cuam tshuam nrog cov filaments koj yuav paub tias qhov nyuaj ntawm ntug dej hiav txwv uas pom zoo ntawm cov khoom siv yooj ywm yog nyob qhov twg los ntawm 100A txog 75A.
Qhov twg, pom tseeb, cov khoom siv luam ntawv 3D uas yooj ywm uas muaj ntug dej ntawm 100A yuav nyuaj dua li qhov muaj 75A.
