Kev Raug Mob Thiab Kev Tswj Xyuas Kev Zoo Ntawm Cov Hlau 3D Printing Tshuab

Ib qho ntawm cov kev sib tw precision ntawm cov hlau 3D tshuab luam ntawv tshuab
Ib qho ntawm cov hlau 3D luam tawm thev naus laus zis cov txiaj ntsig tseem ceeb yog nws qhov kev ntsuas zoo. Nws qhov tseeb theoretically tuaj yeem 0. {{} Millimeters lossis txawm zoo dua. Hauv kev siv tswv yim, txawm li cas los xij, qhov dav dav dav dav yog li ntawm 0. 16m / 1 {} 0mm, nrog kev txwv ntawm ± 0.05mm; Qhov precision ntawm cov khoom siv tseem ceeb yog feem ntau tswj tsis pub dhau 0.05 millimeters. Txawm hais tias qhov tseeb ntawm qhov tseeb yog qhov siab tiag tiag, hauv qee qhov kev thov tshwj xeeb yog tseem xav tau kom muaj kev tsim qauv tsim.
Laser ruaj khov, tshuaj ntsuam ceev, hmoov txheej thickness, thiab lwm yam cuam tshuam rau cov khoom siv hlau 3D luam tawm ntawm lwm cov ntsiab lus. Qhov kev sib cuam tshuam ntawm cov ntsiab lus no ua rau kom nce cov khoom siv dav dav tau raug ntau dua.
Qhov cuam tshuam ntawm cov yam ntxwv kho tshuab: Cov yam ntxwv ntawm lub cev thiab lub cev ntawm ntau yam khoom hlau txawv txawv; Cov xwm txheej no suav nrog melting point thiab thermal nthuav kev coefficient, uas tej zaum yuav cuam tshuam rau qhov tseeb thoob plaws hauv cov txheej txheem luam ntawv. Piv txwv li, qee cov ntaub ntawv muaj feem ntau yuav kub ntxhov thaum lub sij hawm yaj melting, uas ua rau muaj kev tiv thaiv sib xyaw lossis tawg.
Ntau tus txheej txheem tsis-nrog rau lub zog laser, ntsuas ceev, txheej thickness, hmoov particle loj, thiab lwm yam.-Tau siv hauv cov hlau 3D luam ntawv. Precision tswj nyob ntawm qhov kev ua kom zoo ntawm cov yam ntxwv no; Txawm li cas los xij, hauv kev xyaum ua haujlwm nws qee zaum nyuaj rau txheeb xyuas qhov zoo tagnrho, yog li hloov pauv hauv precision raws li.
Tsis tsuas yog precision tseem ceeb rau qhov zoo ntawm cov hlau 3D luam tawm cov khoom siv, tab sis kuj muaj ob peb lwm yam nrog rau qhov chaw tsis zoo, sab hauv, cov yam ntxwv kho tshuab. Cov cheeb tsam no 'tswj hwm cov teeb meem ib yam nkaus.
Kev tswj kom zoo: kev hloov pauv hauv cov hmoov txheej txheej tuab, thiab kev ua haujlwm ntawm cov tshuab ua kom zoo nkauj ntawm cov hlau 3D luam tawm ntu. Kev cuam tshuam ncaj qha rau cov tsos thiab kev ua tau zoo yog nplaim roughness, waviness, thiab lwm yam ntsuas.
Cov khoom siv 3D tau muaj feem cuam tshuam nrog cov flaws xws li, thiab pores uas muaj kev cuam tshuam rau cov neeg kho tshuab thiab kev pabcuam lub neej ntawm cov khoom siv. Cov kev ntsuas tsis yog-kev sim X-ray, thiab lwm yam. Nrhiav qhov tseeb ntawm cov qauv geometric thiab sab hauv cov qauv ntawm cov hlau 3D luam tawm cov khoom siv hlau. Micro CT nrhiav tau yog kim thiab muaj qee qhov kev txwv ntawm qhov loj me thiab cov khoom siv txawm tias nws muaj kev daws teeb meem zoo thiab muaj peev xwm nrhiav tau.
Cov kev tswj hwm neeg kho tshuab tswj tau hais txog cov ntsiab lus sib txawv cuam tshuam rau cov neeg kho tshuab zoo: Cov Txheej Txheem Luam Ntawv, thiab cov khoom siv kub. Cov lus qhia sib txawv ntawm cov neeg siv cov khoom siv tau ua rau feem tsis ua haujlwm thaum lub sijhawm ua haujlwm. Txuas ntxiv heev rau cov khoom siv neeg yog kev xaiv thiab ua kom zoo ntawm kev kho cua sov; Tab sis, hauv kev ua haujlwm ua tau zoo no qee zaum nyuaj rau kev tswj hwm meej.
Cov kev daws teeb meem rau cov teeb meem kev tswj hwm thiab kev tswjhwm zoo ntawm cov tshuab ntaus hlau 3D tuaj yeem nrhiav tau hauv cov spheres hauv qab no:
Cov Khoom Siv Kev Tsim Kho Kom Zoo thiab Hloov Kho: Qhov tseeb ntawm cov khoom siv tau tsa los ntawm kev ruaj ntseg ntawm laser, kev nrawm nrawm dua, zoo txheej txheej thiab lwm yam. Kev qhia tib txhij ntawm cov tswj niaj hnub thiab sensors tsom rau muab kev soj ntsuam kev kawm tiag tiag thiab kev tswj hwm ntawm cov txheej txheem luam ntawv.
Kev tshawb fawb txog cov ntaub ntawv thiab kev xaiv: Tsim cov ntaub ntawv tshiab hlau kom txaus siab ntau lub sijhawm thov los ntawm kev ua kom zoo tshaj thowphophysical thiab luam tawm cov yam ntxwv. Conmination nrog qhov no, kev tshawb nrhiav kom zoo rau cov ntaub ntawv tam sim no yuav tsum tau coj tus cwj pwm thoob plaws hauv kev luam ntawv, yog li muab cov moj khaum the srametical rau txheej txheem ntsuas kev ua kom zoo.
Ua qauv thiab ua kom cov txheej txheem ua kom zoo dua: los ntawm kev tshawb fawb kev sim thiab cov ntaub ntawv kev tshuaj xyuas, txheeb xyuas cov txheej txheem cov txheej txheem specifications. Qhov no pab kom txo cov kev sib txawv hauv qhov tseeb thiab qhov zoo thiab yog li txhim kho kev sib xws thiab muaj kev vam meej ntawm cov khoom siv.
Tsis yog-cuam tshuam kev sim thev naus laus zis: kev txhim kho tshiab thiab cov qauv kev soj ntsuam cov qauv kev sib tw tsis muaj kev tsim kho cov qauv hlau 3D luam tawm cov khoom lag luam. Tsim ultrasonic kuaj thiab cov cuab yeej haum rau cov khoom siv hlau 3D; Siv cov duab muaj zog txheej txheem thiab dag ntxias thev naus laus zis los ua kom raug qhov tseeb thiab ua haujlwm ntawm micro ct nrhiav tau.
Cov kws kho tshuab cov khoom ua ntej thiab kev tswj hwm: Tsim cov txheej txheem kev ua si 3D luam tawm cov txheej txheem kev tswj hwm, txheej txheem kho cua sov, lwm yam parameter ua kom zoo thiab tswj. Concurrent nrog cov lus qhia no ntawm kev ntsuas kev ua haujlwm thiab cov cuab yeej tshuaj ntsuam thiab kev soj ntsuam ntawm kev ua haujlwm txhua yam.
