| Abstract Scope |
Achieving high-performance multi-material resins for 3D printing in biomedical applications demands careful formulation strategies to enable the integration of components with desirable properties. When building tissue engineered scaffolds for critical sized bone defects, high interconnected porosity with a vascular network and mechanical reinforcement are key components for success. Polymer selection can generate targeted cell adhesion to promote both vascular and bone integration while ceramic reinforcement can provide enhanced mechanical stability. This talk will explore multi-material resins for incorporating zonal cell adhesion with different polymer resins and mechanical enhancement through the incorporation of a ceramic-polymer resin. A range of photosensitive resin formulations based on polyethylene glycol diacrylate blended with natural based polymers with or without TiO₂ reinforcement will be highlighted to meet these challenges. This innovative set of multi-material resins for vat photopolymerization will be used to enhance both scaffold printability and mechanical properties for biomedical applications. |
