description A tissue engineering scaffold of interconnected and bonded fiber having a property with a value that is spatially distributed in at least two regions is provided. The scaffold has at least two regions with properties, such as porosity, strength, elastic modulus, osteoconducti vi ty, and bioactivity that can be controlled and modified through fabrication processes that alter the pore size, pore size distribution, composition, and bonding of fiber and other additives. The value of the property can be provided with a gradient between each of the adjacent spatially distributed regions. La présente invention concerne un échafaudage pour ingénierie tissulaire de fibres interconnectées et liées ayant une propriété avec une valeur spatialement distribuée dans au moins deux régions. L'échafaudage a au moins deux régions avec des propriétés, telles que la porosité, la résistance, le module d'élasticité, l'ostéoconductivité, et la bioactivité qui peuvent être régulées et modifiées par des procédés de fabrication qui modifient la taille de pores, la distribution de la taille de pores, la composition, et la liaison des fibres et autres additifs. La valeur de la propriété peut être dotée d'un gradient entre chacune des régions adjacentes distribuées dans l'espace.
