Experimental Setup for Fatigue Testing of Additively Manufactured Specimens

Poor fatigue life is a huge issue of additively manufactured parts, despite the unique qualities characterizing this manufacturing process (such as low waste material and geometry freedom). Fatigue strongly affected by both surface defects internal defects, metal AM characterized extremely poor quality, porosities lack fusions. For reason, many researchers investigated methods to improve manufacts quality. The most promising are finishing treatments thermal which provide an enhancement behavior. A focal point research should be evaluating respective contribution treatments. In order evaluate effectiveness treatment, it necessary highlight quality in terms thus specific testing method necessary. Rotating beam test fits requirement because each specimen’s subjected maximum stress. aim work present experimental setup for rotating that has been used behavior SLM IN718 specimens.
