Vim li cas Kev Kho Mob Kev Lag Luam Yuav Tsum Muaj Qhov Zoo Tshaj Plaws?

"Qhov zoo li zoo - Vim li cas koj thiaj thov kom muaj qhov zoo dua?"

"Peb twb tau luam ib feem. Nws zoo nkaus li zoo. Vim li cas peb thiaj xav tau polishing ntxiv?"

Yog tias koj tau ua haujlwm nrogHlau 3D Printing, tej zaum koj twb muaj kev sib tham no.

Los ntawm tus neeg yuav khoom qhov kev xav, geometry yog qhov tseeb, cov qauv ua tiav, thiab txhua yam zoo li "tiav lawm." Tab sis nyob rau hauv daim ntawv thov kev kho mob, tsos tsis zoo ib yam li usability - thiab yeej tsis zoo ib yam li kev nyab xeeb.

Nov yog cov lus teb tiag:

Hauv kev lag luam kho mob, qhov zoo ntawm qhov chaw cuam tshuam ncaj qha rau kev nyab xeeb, kev ua haujlwm, thiab kev tswj hwm kev pom zoo.

Txawm hais tias koj tab tom ua haujlwm nrog Kev Tsim Khoom Ntxiv lossis tshawb nrhiav Topology Optimization Additive Manufacturing rau qhov nyuaj, qhov zoo ntawm qhov chaw tsis yog qhov nthuav dav - nws yog qhov yuav tsum tau ua.

Cia peb rhuav nws hauv qhov ua tau zoo, tsis muaj - txoj kev tsis muaj tseeb.

Surface Quality in Medical=Kev nyab xeeb, Tsis yog Kev Zoo Nkauj xwb

Hauv cov ntawv thov kev lag luam, qhov chaw tiav feem ntau yog hais txog:

Qhov tshwm sim

Kev sib txhuam

Kev sib dhos haum

Hauv kev siv tshuaj kho mob, nws mus tob dua.

Raws li kev taw qhia los ntawm US FDA, 3D luam tawm cov cuab yeej kho mob yuav tsum tau ua raws li kev nyab xeeb thiab kev ua tau zoo, thiab tshaj tawm - cov kauj ruam ua haujlwm xws li ntxuav thiab polishing feem ntau yuav tsum tau ua ntej siv.

Qhov no txhais li cas hauv lub neej tiag tiag:

Ib qho chaw uas "zoo txaus" rau cov khoom lag luam yuav tsis tuaj yeem lees txais rau kev siv kho mob.

Yog vim li cas 1: Nto Roughness tuaj yeem cuam tshuam rau tus neeg mob kev nyab xeeb

Cia peb pib nrog qhov tseem ceeb tshaj plaws.

Rough nto tuaj yeem:

Cuam kab mob

Khaws cov pa phem

Ua kom tsis muaj menyuam

Qhov no yog qhov tshwj xeeb tshaj yog rau:

Cov cuab yeej phais

Kev cog hniav

Cov khoom siv hauv kev sib cuag nrog cov ntaub so ntswg

Vim li cas qhov no tseem ceeb:

Txawm tias microscopic nto irregularities tuaj yeem ua:

Cov kab mob loj hlob

Kev pheej hmoo kis mob

Tias yog vim li cas qhov chaw smoother yuav tsum tau - tsis yog rau kev zoo nkauj, tab sis rau kev nyiam huv.

Yog vim li cas 2: Nto Zoo cuam tshuam rau Biocompatibility

Txawm hais tias cov khoom nws tus kheej muaj kev nyab xeeb, qhov chaw saum npoo tuaj yeem hloov pauv li cas lub cev ua haujlwm.

Kev tshawb fawb qhia tau hais tias qhov chaw saum npoo av thiab kev ua tiav tuaj yeem cuam tshuam li cas cov ntaub ntawv biomedical coj lub sijhawm, suav nrog kev ruaj khov thiab degradation.

Hauv cov ntsiab lus yooj yim:

Tib yam khoom

Txawv nto tiav

Kev ua tau zoo sib txawv kiag li

Piv txwv:

Rough implant → irritation los yog o

Tswj nto → ruaj khov kev koom ua ke

Yog vim li cas 3: Additive Manufacturing tsim ib txwm ntxhib nto

Wb tham txog qhov tseeb ntawmAdditive Manufacturing Txheej txheem.

3D luam ntawv tsim cov txheej txheem los ntawm txheej.

Qhov no tsim:

"Stair-step" cuam tshuam

Nto irregularities

Variable roughness nyob ntawm lub kaum sab xis

Kev tshawb fawb qhia tau hais tias qhov chaw roughness nyob rau hauv additive manufacturing yog heev nyob ntawm cov txheej txheem tsis thiab geometry, ua rau nws nyuaj rau tswj tsis tau post- ua.

Qhov no txhais li cas rau cov neeg yuav khoom:

Txawm nrog cov tshuab siab heev:

Cov ntawv luam tawm nyoos yuav luag tsis zoo txaus rau kev siv kho mob

Yog vim li cas 4: Complex Designs (Topology Optimization) Ua kom nyuaj

Cov qauv siv niaj hnub sivTopology Optimization Additive Manufacturingtsim:

Lub teeb yuag

Organic duab

Sab hauv channels

Qhov kev sib tw:

Cov qauv tsim no zoo rau kev ua haujlwm - tab sis nyuaj rau kev ua tiav.

Nyuaj-rau- ncav cuag qhov chaw

Sab hauv kab noj hniav

Complex geometry

Qhov tshwm sim:

Kev xav tau siab dua rau:

Advanced txheej txheem tiav

Tswj kev tshaj tawm - ua tiav

Yog vim li cas 5: Qhov Zoo Tshaj Plaws cuam tshuam rau kev ua haujlwm ntawm cov tshuab

Nto tiav tsis yog cuam tshuam rau cov tsos - nws cuam tshuam lub zog.

Raws li FDA-Txoj kev tshawb fawb ntsig txog, kev hloov pauv hauv cov txheej txheem tsim khoom ntxiv tuaj yeem cuam tshuam rau kev ua haujlwm thiab kev ntseeg siab.

Vim li cas qhov chaw tseem ceeb:

Rough surfaces=stress concentration point

Micro- tawg tuaj yeem pib ntawm qhov tsis xws luag

Txo qaug zog lub neej

Hauv cov khoom siv kho mob, qhov no tseem ceeb heev.

Txawm tias me me defects tuaj yeem ua rau:

Kev tawg

Ua tsis tiav raws sijhawm

Yog vim li cas 6: Cov kev cai yuav tsum nruj dua

Ntawm no yog ib yam dab tsi ntau buyers underestimate:

Cov khoom kho mob tsis raug txiav txim los ntawm seb lawv zoo li cas - tab sis los ntawm qhov lawv tau lees paub.

Kev tswj hwm kev cia siab muaj xws li:

Tswj qhov chaw tiav

Txheeb xyuas cov qib roughness

Cov txheej txheem rov ua dua

Cov ntaub ntawv tag nrho

Raws li FDA cov lus qhia, cov tuam txhab lag luam yuav tsum tau lees paub cov txheej txheem ob qho tib si thiab cov khoom lag luam kawg kom ntseeg tau tias muaj kev nyab xeeb thiab ua haujlwm tau zoo.

Hauv cov ntsiab lus yooj yim:

Koj tsis yog xav tau qhov chaw du -
koj xav tau ib txoj kev rov ua dua, ua pov thawj kom ua tiav.
