Abrégé
(EN)
A design methodology is provided for creating biomaterial scaffolds optimized for in vivo function with any 3D anatomic shape. The method creates all designs using voxel based design techniques. It also provides for optimization of implant and scaffold microstructure to best match functional and biofactor delivery (including cells, genes and proteins) requirements. The voxel based design techniques readily allow combination of any scaffold or implant microstructure database with any complex 3D anatomic shape created by CT or MRI scanners. These design can be readily converted to formats for layered manufacturing or casting.

L'invention concerne un procédé de conception d'échafaudages de biomatériaux optimisés destinés à une fonction in vivo et épousant n'importe quelle forme anatomique 3D. Ce procédé utilise des techniques de conception basées sur le voxel pour créer l'ensemble de ces échafaudages. L'invention concerne également l'optimisation des microstructures d'échafaudages et d'implants pour que celles-ci répondent au mieux aux exigences de l'apport fonctionnel et biofactoriel (notamment les cellules, les gènes et les protéines). Ces techniques de conception basées sur le voxel permettent de combiner rapidement n'importe quelle base de données de microstructures d'échafaudages ou d'implants avec n'importe quelle forme anatomique 3D complexe créée par les scanners CT ou IRM. On peut facilement convertir ces conceptions en formats adaptés pour la fabrication de stratifiés ou le moulage.
