Abstract

Un maillage structural pour une construction tissulaire peut comprendre un boîtier maillé formé pour renfermer partiellement ou complètement une construction tissulaire. Le boîtier maillé peut comprendre un matériau maillé ayant une rigidité suffisante pour que le boîtier maillé fournisse un support structural tandis que la construction tissulaire maintient une pression interne à partir de la circulation sanguine. Les pores dans le boîtier maillé peuvent permettre le transport d'oxygène et de nutriments entre la construction tissulaire et un environnement ambiant.
