Abstract
The poor performance of 3D-printed components in extreme conditions is investigated. It is found that macroscopic crystal lattice defects are formed at the boundary between the layers in additive manufacturing and high internal stress develops. That may be regarded as the main factor impairing the mechanical properties of 3D-printed metal. Additional heat treatment is required to improve the mechanical properties.
