Title: Mechanical Properties Testing for Metal Parts Made via Additive Manufacturing: A Review of the State of the Art of Mechanical Property Testing
Published: March 26, 2012
Abstract: Determining the properties of the powder used for metal‐based additive manufacturing, as well as the properties of the resulting bulk metal material, is a necessary condition for industry to be able to confidently select powder and produce consistent parts with known and predictable properties. This report assesses the current state-of-the-art methods for determining the mechanical properties of bulk metal materials. Emphasis of this assessment was on existing internal standards that cover the measurement of mechanical properties of metal parts. This assessment will later be used as the basis to develop standardized test methods that are appropriate for metal parts made via additive manufacturing.
