Schematic diagram of experimental procedures and scaffold design used for the bone regeneration study. The left panel shows the custom-built melt electrowriting device. In the middle panel, diagrammatic representation of the different scaffold structures and SEM images of 3D printed scaffolds. The right panel illustrates the uniform hydroxyapatite coating process on the surface of the porous scaffolds by soaking in SBF and subsequent implantation of the scaffolds into a calvarial defect in rats
