Preparation and Performance Analysis of Mesh Hydroxyapatite/Sodium Alginate Composite Scaffold

Abstract

Scaffolds material is the key factor for bone tissue engineering, and construction of the scaffolds is also an important part. Adopting the biocompatible, biodegradable, hydroxyapatite (HAP) and sodium alginate (SA) as the molding material, using three-dimensional printing technology, choosing cross grid filling paths, we manufactured the artificial bones through self-developed 3D printing equipment. Then we measured and analyzed important parameters of the work, and did composite culture experiment. It can be seen that the prepared artificial bone scaffold has good biocompatibility. The paper provides a reference for the study of bone tissue engineering materials.
