Due to recent advances in technologies, brought on both at the high-tech industry level (3DSystems, Stratasys) and the user level (Solidoodle, MakerBot), additive manufacturing technologies have been increasingly sought for end-use manufacturing as opposed to rapid prototyping only. This leads to many questions about the engineering application of these technologies. Many researchers have been studying methods for increasing static strength properties of AM materials since their introduction. However, little research has been done on fatigue properties of these materials. This task is undoubtedly made harder by the proprietary nature and process dependency of the materials involved, particularly for the SLA and SLS processes. The FDM process, however, uses commercially available ABS plastic. The research in this paper, therefore, focuses on this process currently. Physical testing for identifying mechanical and fatigue characteristics, including tensile strength and high and low cycle fatigue, is conducted in close accordance with the applicable ASTM standards.
