| Abstract Scope |
Bioactive ceramics like hydroxyapatite (HAP) offer favorable osteoconductive properties for bone regeneration. This study focuses on the characterization of HAP components with interconnected porosity, evaluating their physiochemical properties during additive manufacturing / sintering processes. The developed material formulation with promising ceramic content supports printing and sintering complex shapes. The produced HAP samples are characterized by scanning electron microscopy, X-ray diffraction, and energy dispersive spectroscopy. Additionally, a continuum theory of sintering-based model was developed to predict the evolution and distortions of the net-shape bioceramic components during the sintering process. This approach provides valuable insights into the fabrication and potential applications of bioceramic scaffolds for critical-sized bone defects. |
