| Abstract Scope |
Magnesium alloys have gained special attention for orthopedic applications due to comparable structural stiffness as that of bones, increased bio-absorption, and reduced bi-toxicity. The current state-of-the-art in this field is the development of bio-compatible magnesium alloy composites which are tailored for specific mechanical properties and corrosion rate for location specific patient needs and to control the bio-absorption rate, while aiding the healing process. However, the current manufacturing process involves use of powder Mg blended with reinforcement phases packed and extruded to get bulk composite, which is lengthy, expensive, and unsafe. In this research, we study feasibility of synthesizing Magnesium – Hydroxyapatite (Mg-HA) composite with various volume fractions in single step using SolidStir® composite 3D printing process. A detailed microstructural and mechanical property characterization results from this study will be presented and feasibility of synthesizing and depositing near net shape tailored biodegradable implants using SolidStir® 3D printing technology will be discussed. |
