ASTM International’s committee on additive manufacturing technologies (F42) is developing a standard-guide for mechanical testing of additively manufactured plastics (WK66029). The guide aims to incorporate what has been learned about mechanical testing modification, interpreting results, and validating test methods with respect to additively manufactured polymer parts.
The standard is a project of ASTM International’s Additive Manufacturing Center of Excellence, led by Wichita State University’s National Institute for Aviation Research (NIAR), launched last year to accelerate R&D, standardization, and innovation in additive manufacturing.
Within WSU-NIAR, the National Center for Advanced Materials Performance (NCAMP) is developing material property data and statistical analysis reports for additively manufactured materials based on input from industry steering committees and government review boards.
Based on lessons learned through the first additive qualification program under the NCAMP process (ULTEM 9085), NIAR is conducting a round-robin study to better understand alternative methods and geometries that more appropriately characterize additively produced specimens. The study aims to drive consensus across multiple ASTM committees (F42 & D20) and offer universally-acceptable guidance for the AM industry.
