Advanced additive manufacturing of melilite bioceramic scaffolds supported by silicone-based nanoemulsions

The experiment involves the study of nanoemulsions that can be polycrystalline alternatives to bioglass for their excellent characteristics of bioresorbability, biocompatibility and bioactivity and high mechanical properties. They are composed of calcium, magnesium and zinc oxide mixed with polymerizable silicones and a surfactant. They differ in the different ratios of zinc and magnesium oxide. Through stereolithography, these nanoemulsions are used to print 3D scaffolds with gyroidal geometry, which are subsequently subjected to a ceramization process. Tests and mechanical analyses are then carried out to evaluate the properties, the specific influence of ZnO and MgO on the final properties of the material and the overall performance of the scaffolds. The results of the study lay the foundation for future developments in the field of biomaterials.
