Each year millions of people suffer from bone defects resulting from trauma, tumors or bone-related injuries. Therefore there is a need to continuously develop new materials or improve the properties of the materials currently used, for bone replacement or implant applications. Polymethyl methacrylate (PMMA) has proven to be a promising alternative as a material for implants; however, there are still some limitations inherent to this material, particularly related to its surface properties. This thesis work is focused on the fabrication of hydroxyapatite (HAp) thin films on the surface of 3D printed PMMA substrates. 3D printing, particularly the Fused Deposition Modeling (FDM) technique was used to fabricate PMMA substrates with different surface porosity levels. FDM technique exhibits the potential for fabricating customized freeform structures for several applications including craniof...
