Nine Projects Supported by ASTM International

Global standards developer ASTM International recently announced that its second round of funding—an investment worth $300,000 and in-kind contributions—will be put toward nine projects that support research in expedited standards for additive manufacturing (3D printing).

According to the developer’s news release, the funding will support ASTM International Additive Manufacturing Center of Excellence’s goal of addressing pressing needs for technical standardization in the fast-growing industry.

“We are thrilled to fund some of the most crucial and high-impact research projects in additive manufacturing to accelerate standardization,” said ASTM International’s Director of Global Additive Manufacturing Programs, Mohsen Seifi.

Seifi added that the nine projects chosen—approved by an ASTM International subcommittee, which focused on research and innovation (F42.90.05)—will complement the previous round of five and target a vast array of topics that contribute to a holistic approach that fills standard gaps in design, feedstock, process, post processing, testing and qualification.

The nine projects include:

  • Auburn University will be working to implement a new inspection process that detects potential part quality issues after fabrication through laser powder bed fusion (L-PBF). The study aims to identify and quantify deviations in build and material quality through a series of tests performed within a few hours after the part is removed from the 3D-printing machine;
  • Auburn University and NASA have partnered to continue work from Phase l of a previously funded project that developed consensus regarding minimum requirements for L-PBF machines and processes. In Phase ll, the team plans to establish qualitative and quantitative metrics for evaluation methods, conduct round-robin trials and establish recommendations for standards implementation;
  • EWI’s project involves defining a minimum subset of AM data entries and taxonomy of those entries. The resulting standard will help establish best practices for data sharing, a common data dictionary for AM and a data management roadmap that integrates stakeholder needs;
  • Manufacturing Technology Centre will address the lack of guidelines for what is deemed an acceptable test result in powder feedstock test methods and aims to help stakeholders understand acceptable test results as well as typical variation in results from different labs;
  • MTC will also work to develop a guide that proposes best practices in design for each type of post-processing operation, in addition to addressing the growing number of post-processing issues tied to inefficient designs, cost, high non-conformity and scrap rates;
  • National Additive Manufacturing Innovation Cluster will use off-axial monitoring to acquire optical and thermal images from the L-PBF process. Image analysis will allow them to extract structured data, ultimately helping develop a procedure to construct a 3D file embedding with parameters both representing the printing process and quality evaluation;
  • NAMIC will also be researching to form guidelines and best practices specific to directed energy deposition and material extrusion and as a conclusion, will provide an overall document structure and guidelines for standard development;
  • Wichita State University’s National Institute for Aviation Research will study existing polymer characterization activities to create a test plan and matrix incorporating the state of the art for these testing methods. Following the study, NIAR plans to share the results and develop appropriate documentation based on its findings; and
  • NIAR will also research coupon-part property relationships in additively manufactured polymers in order to review results from multiple studies and compile an approach for microstructural analysis of specimens as well as application-specific characterization.
