The scaffolds play an important role in tissue engineering which is a research field for artificial substitutes, since they act as substrates for cell adhesion, proliferation and regeneration of new tissue. In this study, a biodegradable Mg-PCL complex scaffold was developed for bone tissue engineering applications. They were made by mixing polycaprolactone (PCL) as base matrix and some magnesium-ion compound particles, and solid Freeform (SFF) method was used for their fabrication. As a result, the developed scaffold had the following characteristics. Firstly, by contact angle measurement, we knew that their hydrophilicity was enhanced due to adding magnesium-ion compound. Secondly, the compressive mechanical test showed that their elastic modulus was higher than pure PCL scaffolds. Thirdly, the in-vitro cell culture study showed that cells in new scaffolds proliferated faster than in the case of the PCL scaffolds. Consequently, it is found that the Mg-PCL complex scaffold is more effective and suitable substrates for cell culture
