Undoubtedly, a better understanding and the further development of approaches for damage tolerant component design of AM parts are among the most significant challenges currently facing the use of these new technologies.

This article presents a thorough overview of the discussion at an international workshop on the topic. It aims to provide a review of the parameters affecting the damage tolerance of parts produced by additive manufacturing (shortly, AM parts) with special emphasis on the process parameters intrinsic to the AM technologies, the resulting defects and the residual stresses. Based on these aspects, basic concepts are reviewed and critically discussed specifically for AM materials:

• -
  Criteria for damage tolerant component design;
• -
  Criteria for the determination of fatigue and fracture properties;
• -
  Strategies for the determination of the fatigue life in dependence of different manufacturing conditions …
