 Scaffolds are used in tissue engineering to provide a structure for cells to attach, grow, and differentiate into functional tissues. These structures must meet certain criteria such as mechanical properties, surface characteristics, porosity, degradability, and biocompatibility. Designing the ideal scaffold for a particular application requires consideration of both material selection and manufacturing process. In this study, PCL slash graphene scaffolds were produced using an extrusion-based additive manufacturing system and evaluated for their biological performance. The results showed that the addition of graphene led to improved cell viability and proliferation, suggesting that surface modification can improve the performance of scaffolds.
