3D Printing Implants - Hlau Biomaterials - Titanium Alloys
Qhov zoo:Biocompatibility, muaj zog tshwj xeeb, siab corrosion kuj, hnav, tsawg fusion tsis xws luag thaum 3D luam ntawv
Daim ntawv thov:Hlau implants xws li pob qij txha, pob txha taub hau, kev cog hniav
Kev sib tw ntawm 3D luam ntawv titanium implants
Kev siv orthopedic biomaterials tau nce ntau nyob rau ob peb xyoos dhau los raws li cov neeg muaj hnub nyoog thiab cov neeg mob xav kom muaj kev ua haujlwm zoo ib yam thiab lub neej zoo. Tsav los ntawm qhov kev thov loj heev rau kev kho mob orthopedic biomaterials, pob txha cov ntaub so ntswg engineering tau tsim sai heev, thiab ntau cov khoom siv orthopedic biomaterials tau tshawb fawb thiab tsim. Hlau-based thiab magnesium-based biomaterials tau siv dav nrog kev pab ntawm 3D thev naus laus zis. Piv nrog cov hlau-raws li thiab magnesium-based biomaterials, titanium-based biomaterials muaj lub zog siab, tsis tshua muaj kev hloov pauv, thiab biocompatibility zoo dua. Biomaterials nthuav qhia qhov tshwj xeeb thiab kev sib tw zoo.
3D luam ntawv titanium-based biomaterials tuaj yeem kho raws li qhov sib txawv ntawm cov neeg xav tau. Nws tuaj yeem tsis tsuas yog tsim cov txheej txheem nyuaj, tab sis kuj muaj qhov zoo sib xws ntawm cov nqi, kev tsim khoom, thiab kev hloov kho tus kheej. Nws tuaj yeem txhim kho cov thev naus laus zis no hauv orthopedics, kho hniav, thiab lwm yam, thiab daim ntawv thov plawv. Txawm li cas los xij, cov thev naus laus zis no tseem ntsib ntau yam teeb meem, xws li yuav ua li cas sib npaug ntawm kev sib raug zoo ntawm cov pob txha pob txha loj hlob thiab cov khoom siv tshuab, kev xaiv cov cuab yeej tsim khoom siv ntxiv, thiab kev ua kom zoo dua qub.
Btxias txias
(1) Txawv 3D luam ntawv thev naus laus zis muaj qhov sib txawv ntawm thermal scanning ceev, fais fab mov, deposition npaum li cas, thiab lwm yam. Piv nrog rau cov txheej txheem ib txwm, 3D luam ntawv npaj txheej txheem muaj cov yam ntxwv ntawm ceev ceev cua sov thiab txias, uas yuav tsum tau meej tswj cov txheej txheem tsis. tau cov khoom zoo thiab txhim khu kev qha;
(2) Muab faib thiab piav qhia txog topology ntawm cov pob txha cov ntaub so ntswg, taw qhia tias ib txoj hauv kev los txo qhov tawv nqaij yog kom rationally optimize topology ntawm cov pob txha porous hloov, yog li txo qhov sib txawv ntawm txhav ntawm cov pob txha hloov thiab tus tswv tsev pob txha, li no alleviating kev nyuaj siab. tiv thaiv lo lus nug.
(3) Kev cuam tshuam ntawm cov yam ntxwv ntawm cov cua kub ceev thiab cua txias ntawm microstructure evolution ntawm titanium alloys yog soj ntsuam, thiab cov khoom siv kho tshuab tuaj yeem txhim kho los ntawm kev kho ob-theem muaj pes tsawg leeg thiab microstructure;
(4) Txaus siab rau biocompatibility thiab osseointegration ntawm ntxeem tau titanium alloys tom qab cog; 3D luam ntawv hlau yog tsim tau zoo dua los ntawm kev tsim cov cuab yeej digital muaj zog, xws li tshuab qauv thiab kev kawm tshuab ua ke nrog cov kev paub txog metallurgical.
Nws tau taw qhia tias kev txhim kho kev txheeb xyuas zoo thiab cov ntawv pov thawj yuav tsum xav kom muaj kev nkag siab zoo ntawm cov txheej txheem tsis zoo thiab muaj feem cuam tshuam rau kev ua haujlwm qaug zog. Rau txoj kev 3D luam ntawv geometries xws li ntxeem tau thiab lattice qauv, kev soj ntsuam zoo dua, cov txheej txheem scanning, thiab cov txheej txheem kev ntsuam xyuas tsis muaj kev puas tsuaj yuav tsum tau tsim.
Tsis tas li ntawd, kev siv tas mus li ntawm kev txawj ntse txawj ntse thiab tshuab kev kawm algorithms muab cov lus qhia kev tshawb fawb rau kev xaiv cov txheej txheem ua, uas tuaj yeem txhim kho qhov zoo ntawm cov khoom thiab txo tus nqi ntawm kev sim thiab kev ua yuam kev. Thiab kev kawm tshuab kuj tseem tuaj yeem hloov kho cov txheej txheem-microstructure-property kev sib raug zoo raws li kev paub dhau los. Nws tau hais meej tias 3D luam ntawv database yuav tsum tau ua kom muaj zog los tsim lub hauv paus rau kev ua kom zoo rau kev sim tsim thiab ua kom tus kheej tsim kho kom zoo.
