Abstract Scope Additive manufacturing (AM) has been extensively studied for generating patient specific 3D constructs of bioresorbable magnesium (Mg) alloys for orthopedic applications. Reactivity of Mg and presence of the inherent oxide limits AM of Mg yielding constructs with inferior resolution, mechanical, and materials properties. An AM method exploiting sheet lamination and additive manufacturing (SLAM) offers a creative solution wherein the sheet feedstock obviates powder use and the consequent limitations of powder based conventional AM. This presentation will discuss the SLAM process parameters of temperature, pressure, time, and more importantly, surface roughness tailored to minimize geometric deformation of engineered pores. Results reveal surface finish as a key parameter for generating mechanically stable Mg constructs with control of pore size, shape, and resolution. Materials-process relationships and in-vitro cytocompatibility results will be discussed demonstrating SLAM as a unique AM approach to fabrication of highly advanced high-resolution 3D constructs of Mg and Mg alloys.
