摘要

This report is the second in a series of reports from the National Institute of Standards and Technology's (NIST's) Engineering Laboratory project titled Materials Standards for Additive Manufacturing. This project provides the measurement science for the additive manufacturing (AM) industry to measure material properties in a standardized way. Currently there are few consensus-based standards in this area. This project, in conjunction with NIST's Fundamental Measurement Science for Additive Processes project, will provide the technical foundation necessary to develop new consensus-based standards. Development of standards will be done via ASTM-Internationals (hereafter referred to as ASTM) Committee F42 on Additive Manufacturing Technologies and the newly formed International Organization for Standardization (ISO) TC261 committee on Additive Manufacturing. 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. By 2014, the project team will develop and deliver enhanced measurement techniques that support new, standardized methods for quantifying the material properties of both the powders used for additive manufacturing and the resulting manufactured products.
