| Abstract Scope |
Given the processing window and established process-structure-property-performance relationships (PSPP) available in additive manufacturing, the format and content of material standards fall short in their ability to communicate the breadth of information relevant to establishing reproducibility, which is foundational to part qualification. Properties such as microstructure, flaw morphology, non-destructive inspection requirements, and the interrelationship with mechanical strength are absent from current material specifications. Given an opportunity to identify the desired material properties and relevant processing details, how would these standards be reformatted? How might a standards development organization (SDO) consider publishing properties consequential of PSPP while still supporting the intent of standardization? This presentation will discuss the ongoing efforts of a working group to develop goal-driven material property standards that are more comprehensive, remain empirically data-driven, and still accommodate the limitations of the volunteer-led nature of new standards authorship. |
