Comprehensive solution of design, material selection and additive manufacturing process of biodegradable scaffold for long bone regeneration.
Many fabrication methods have been investigated in attempts to achieve HA/TCP scaffolds with microporous structure enabling cell growth and nutrient transport. However, current 3D printing methods can only achieve the fabrication of HA/TCP scaffolds with certain range of microporous structure. To overcome this challenge, we developed a slurry-based microscale stereolithography (μSLA), allowing us to form a HA/TCP-based photocurable suspension with complex geometry including biomimetic features and hierarchical porous structures ranging from nanoscale to macroscale.
