Abstract
A method of determining an amount of imperfection in an additively manufactured material is disclosed herein. The method includes forming a sample piece constructed from the material during a same additive manufacturing cycle as a design piece constructed from the material, introducing a first electrical current to the sample piece while maintaining the sample piece at a reference temperature, and determining the amount of imperfection in the material depending on the measured resistance and the reference temperature of the sample piece.
