Fatigue properties in additive manufacturing methods applying Ti6Al4V

Additive manufacturing (AM) is a novel technique for fabricating various types of materials with complicated three-dimensional shapes and controlled porosity. The process is driven by direct coupling from a computer-aided design (CAD) model of the product, from which successive cross-sections (i.e. layers) are calculated. This is a different approach to traditional fabrication methods, such as machining from blocks or plates, where the final parts geometries are produced by subtracting, or removing, material. With this additive approach, parts of greater complexity can be economically produced in a time efficient and resource saving manner. The paper presents a summary of current AM techniques in relation to obtained mechanical and fatigue properties of manufactured elements.
