Cov ntawv fiber ntau tuaj yeem ua kom lub zog ntawm 3D luam tawm hauv ntau txoj hauv kev, los ntawm lub zog thiab txhav mus txog qhov txhav thiab ua kom ntev. Lub peev xwm siv ntau hom kev cai thermoplastics rau 3D luam tawm muab peb txoj hauv kev los nthuav cov ntawv thov ntawm 3D luam ntawv nrog cov khoom uas cov ntawv ntxiv coj. Cov khoom siv nrov 3D luam tawm muaj kev sib xyaw ntawm polyethylene, polypropylene thiab polyurethane, txhua tus tuaj yeem yaj tau yooj yim thiab txias tam sim ntawd.
Ntau cov thermoplastics muaj cov ntsiab lus tsawg melting thiab tsis muaj zog lossis tsis yeem, uas ua rau lawv zoo tagnrho rau cov khoom uas ua rau lawv zoo rau 3D luam ntawv. Cov duab siv los ntawm cov tuam ntxhab pom meej tias cov resins no nyuab dua li tus qauv, tab sis yuav ua li cas cov roj hmab tawv tawv ntxiv tiv thaiv lwm cov yas uas ua los ntawm FDM 3D printers? Txawm li cas los xij, kev sib piv lub zog tensile yog ib txoj hauv kev yooj yim los txiav txim siab seb cov khoom twg yog cov muaj zog tshaj.
Cov ntawv cog lus molecular uas tsim nyob nruab nrab ntawm cov khoom siv thiab qhov kev nthuav tawm nws tus kheej yog yuav luag txhua qhov tshwm sim ntawm ib qho kev rho tawm ntawm cov yas. Lub nplhaib yas qauv tuaj yeem tsim tawm los ntawm kev siv cov ntsuas kub tsis sib xws rau kev luam ntawv, tab sis nrog qhov pib zoo ntawm -180C lub ntsuas kub extrusion yog qhov siab heev. Cov huab cua kub dua yuav ua rau cov pom kev tsaus ntuj thiab cov cua txias dua yuav ua rau sib dua, xws li ib puag ncig 180 ° C.
Qhov tsis kam ntawm 3D qhov khoom tawm tuaj yeem sib txawv vim nws muaj cov qauv sib txawv, thiab nws tuaj yeem sib txawv thaum ntsuas ntawm ob sab ntawm lub nruas dua li thaum ntsuas los ntawm sab saum toj mus rau hauv qab. Nws tseem tuaj yeem sib txawv ntawm qhov loj thiab cov duab, ntxiv rau cov naj npawb ntawm cov khaubncaws sab nraud povtseg, vim li cov 3D luam tawm cov khoom lag luam muaj cov qauv sib txawv.
Piv txwv li, koj tuaj yeem yuav PLA filament impregnated nrog tus neeg txhawb nqa, thiab cov khoom tau txais yuav muaj zog tshaj qhov koj tau txais los ntawm cov ntxhiab dawb, tab sis nws kuj yuav tsis muaj zog heev. Yog tias lub siab ceev khoob, lossis thaum lub siab ntawm ib feem dhau lawm, koj tuaj yeem txhaj cov khoom siv ntxiv mus rau hauv nws kom qhov txiaj ntsig ua rau nws tsis muaj zog.
Txhua yam koj yuav tsum tau ua yog siv rab phom kub kua nplaum los txhaj cov kua nplaum rau hauv sab hauv ntawm qhov khoom thiab tho ob peb lub qhov hauv ob sab.
Qhov no txhais tau tias koj tuaj yeem siv nws zoo li ib txwm muaj tshuab luam ntawv 3D yog tias nws tuaj yeem luam tawm qhov seem dhau ntawm qhov khoom.
Nov yog cov roj hmab ruaj khov uas tuaj yeem siv ua a3D luam ib feem, thiab nws yog ib qho ntawm cov muaj zog thiab ruaj khov tshaj plaws 3D cov ntaub ntawv luam tawm puas tau. ABS yog ABS vim tias lawv muaj zog thiab yooj yim luam tawm, tab sis polycarbonate (PC) yog qhov muaj zog dua thiab muaj ntau dua qub dua li lwm cov plastics xws li polyethylene.
PCs tuaj yeem yuav nyuaj rau 3D luam ntawv vim tias lawv xav tau kev kub kom extrude kom raug, thiab lawv nyiam warp thiab puas tsuaj qhov chaw lawv luam tawm. PC yuav tsum muaj lub punch ruaj khov uas nws tuaj yeem tiv taus, tom qab ntawd nws yuav yog qhov kev xaiv zoo rau koj.
Ib zaug mastered, txawm li cas los xij, muaj zog thiab ruaj khov 3D luam tawm tshuab tuaj yeem tsim rau koj daim ntawv thov kev thov tom ntej. Thaum koj txawj ua nws, txawm li cas los xij, koj muaj peev xwm tsim rugged, ruaj ntseg 3D luam tawm qhov chaw rau cov ntawv tom ntej engineering.
Cov tawv muag muag ntawm cov ntawv lim, tshwj xeeb tshaj yog nyob rau hauv kev sib xyaw nrog tus kheej lub cim ntawm 3D luam ntawv, ua rau nws xaiv zoo rau qib high-end 3D luam ntawv. SemiFlex, NinjaF flex yog qhov ua tau zoo ntawm cov khoom lim uas qhib qhov rooj rau ntau cov kev siv, los ntawm kev lag luam thiab thaj chaw rau cov neeg siv khoom. Ninja Flex muaj nyob rau hauv ntau cov xim uas muaj qhov pom zoo, zoo nkauj thaum tau 3D luam tawm.
Thaum siv hexagonal infill, koj tuaj yeem tsim cov khoom uas tawv rau hauv ib qho kev taw qhia axis, thaum seem tseem mos thiab daim txhuam cev rau ntawm lwm lub axis.
Ib qho ntawm cov xwm txheej uas ua rau cov khoom lag luam tsis muaj zog hauv 3D luam ntawv yog tias ob peb plastics tsim nyog rau siv hauv tshuab luam ntawv. Cov ntaub ntawv yas uas tsis muaj zog xws li polyethylene, polypropylene thiab lwm yam kab hlau tsis zoo tuaj yeem tsim tsis tau los ntawm 3D tshuab luam ntawv. Qee cov khoom lag luam tsim nrog 3-D luam ntawv txheej, tab sis muaj cov laminate tsis muaj zog vim tias tsis muaj qhov sib khi ntawm cov khaubncaws sab nraud povtseg sib txuas thiab kev siv cov yas ruaj khov.
Yog li no, CNC machining feem ntau yog txoj kev zoo tshaj plaws ntawm kev tsim khoom rau cov khoom no vim nws tus nqi qis thiab kev tswj tau yooj yim. Qee zaum qhov kev rhuav tshem ntawm cov phaj luam yuav pab kom nkag siab zoo dua cov ciam teb ntawm ib qho khoom siv.
