| Abstract Scope |
Porous implantable scaffolds act as templates to allow tissue growth and regeneration in 3D. Ideally, structural biomimicry is a commonly-followed criterion so that the scaffold can replicate the trabecular architecture of bone. This is a particularly difficult task when bioactive ceramics and glasses are used for osseous applications due to some challenges related to the inherent characteristics of materials and relevant fabrication processes (e.g. reproducibility, reliability and the need for high-temperature sintering). Recent progresses in the advanced manufacturing of bioceramics have allowed researchers to overcome some of these limitations. The first part of this contribution provides a state-of-the-art overview of porous bioceramics/glasses fabrication by conventional and additive manufacturing technologies. The second part is addressed to the recent strategies developed to integrate the design of truly “bone-like” structures, also driven by computational strategies, into additive manufacturing methodologies, with emphasis on scaffolds exhibiting foam-like architecture and triply-periodic minimal surfaces (TPMS). |
