The role of scan strategies in fatigue performance for laser powder bed fusion

The integrity of additively manufactured components is limited by the number, size, type and location defects encapsulated in build. Our ability to manufacture fatigue resistant powder bed fusion process still nascent as a result. within build volume known be significance but efforts are yet achieve superior manufacturing strategies resulting tolerable performance. In this work role laser scan investigated determining performance printed components. Fractography X-ray computed tomography data presented support this.
