Lus Taw Qhia Cov cuab yeej ntawm tes yog cov khoom siv ntawm tes thiab tau nyiam ntau lub ntsej muag vim tias lawv tuaj yeem replicate cov morphology thiab cov khoom siv kho mob ntawm cov pob txha ntuj. Cov qauv tseem ceeb, xws li porosity, thaj chaw thaj chaw, thiab lub qhov tseem ceeb hauv qhov tseem ceeb hauv kev ntsuas kev ncaj ncees thiab biocompatibility. Ib qho zoo tshaj pob txha scaffold yuav tsum muaj tib lub zog kho tshuab raws li cov pob txha ntuj, thiab MDFG Scaffoldsricated ci los ntawm LPBF ua lub hom phiaj no. Qhov kev kawm no tau soj ntsuam cov MDFG Scaffoldsricated los ntawm LPBF (npog ntau hom kev sib tw sib txawv) los txiav txim siab lawv cov kev siv hauv orthopedic.
Cov ntaub ntawv thiab cov qauv ntawm daim Scaffolds tau ua qauv siv NOTOPology Software. Lub voos xwmfab nrog ib chav nyob loj ntawm 20 hli tau teeb tsa, thiab cov khoom ntim ntim tau ntxiv rau sim ntxias lub cev muaj sia. Cov tsev sib txawv ntau thiab tsawg cov ntsiab lus thiab cov noob noob tau teeb tsa rau ntau hom kev ua yeeb yam ntawm cov qauv qub los tsim cov tshuaj pleev thaiv cov qauv. Cov scaffolds tau muab cov pob tw los ntawm LPBF, luam tawm cov chaw tau nqa tawm, thiab cov hnoos qeev tau coj tawm. Siab - kev voj voog ua kom qaug zog (HCF) tau nqa tawm hauv kev hloov chaw - Kev thauj khoom.
Cov Ntsiab Lus Quality Pression cov kev sim uas pom tias lub gyroid thiab lawv lub zog - kev hloov pauv cov neeg kho mob muaj peb - txheej txheem deformation. Finite - Kev tsom xam cov kev soj ntsuam muab cov ntsiab lus tseem ceeb rau kev sim siab, thiab lwm yam. Los ntawm kev sib piv cov qaug zog - ua tsis tiav cov qauv ntawm kev sib txawv, nws tau pom tias cov kev ua tau zoo tshaj plaws, nws tau ua tiav zoo dua li ntawm Voronoi Lattice, thiab cov Kelvin Mesh muaj kev qaug zog tshaj plaws.
Cov lus xaus rau MDFG Scaffolds, tshwj xeeb tshaj yog cov gyroid thiab cov khoom siv zoo tshaj plaws thiab yog qhov kev xaiv zoo tshaj plaws rau kev thauj khoom. Kev nce qib hauv kev tsim kho scaffold tsim kev ntxhov siab, thiab lwm yam. Kev tshawb nrhiav yav tom ntej yuav tsum tshawb xyuas tus neeg mob - Kev tshawb fawb txog kev ua kom zoo dua thiab hauv - Vivo kev tshawb fawb los txhim kho kev ua haujlwm ntawm cov ntawv thov orthopedic thiab txoj kev vam meej ntawm cov ntawv thov kev kho mob. Hauv kev xaus, MDFG Ti6AL4V Scaffoldsricated los ntawm LPBF muaj kev nthuav dav thov cov kev cia siab hauv thaj teb Orthopedic kev cog lus. Los ntawm kev tshawb nrhiav txuas ntxiv thiab kev txhim kho, nws yuav tsum muab cov kev kho mob zoo dua rau cov neeg mob.
