2022 ASTM Fellowship Awarded for Research in Ceramic 3D Printing – 3DPrint.com

ASTM International has awarded four $10,000 scholarships to graduate students for 2022: Diana Wyman, Kennedy Brown, Menachem Sokolic and Sarah Boardman. Fellowships are awarded to researchers who conduct work on standards in the broadest sense. Before discussing Boardman and his work in 3D printing, we will give a brief summary of the non-additive work of the other three students.

Non-additive scholarships

Prior to working at the American Association of Textile Chemists and Colorists, Wyman was a product researcher for outdoor company REI. She describes herself as a “lifelong student”, pursuing a doctorate. in Fiber and Polymer Science at North Carolina State University. She has contributed to the ASTM D13 (textiles) and F23 (PPE clothing) committees.

Kennedy Brown is completing a master’s degree in civil and environmental engineering at the University of Vermont, with the goal of working on standards and water engineering.

Pursuing an MBA at Rutgers, Menachem is an environmental consultant for Wolf Commercial Real Estate, dedicated to due diligence. He also works within the FalconRE group. He is part of the ASTM E50 committee.

Research on 3D printing of ceramics

Undertake a Ph.D. In materials science at the Colorado School of Mines, Boardman studies 3D printed ceramics. So far, she has worked on “critical failure of alumina made by additive manufacturing, specifically lithography-based ceramic manufacturing (LCM), making connections to strength control defects. “. It’s very timely for her to work on what I call Slurry SLA and ancillary processes, as there has been a lot of development and investment in this area lately. Long a promised land, explored only in spurious claims, SLA slurry can produce tiny pieces with smooth interiors at very little cost.

In this field, she studies “the impact of process parameters on the generation of defects in this printing technique. There is a wealth of data on the mechanical performance of traditionally processed alumina allowing effective comparison with the performance of additively manufactured parts. Using Weibull analysis and fractography, this work will provide much needed insight into the strength variability and critical defect population of LCM-formed alumina. Parts with complex geometries will be analyzed to verify if strength control defects found in single bars are also found in larger, more complex parts. The knowledge generated in this study will help establish more fundamental links between processing conditions and part properties for the LCM ceramic forming technique. The work done here will help determine if traditional ceramic testing standards are effective for ceramic additive manufacturing or if new standards or requirements need to be implemented.

Previously, she worked on the behavior of the high temperature composite superconductor ¨Bi2Sr2CaCu2O8+x (Bi-2212)¨. Boardman is a CoorsTek Fellow in Advanced Ceramics, a reviewer for the Journal of the American Ceramic Society, and president of Women in STEM. She contributed to our beloved F42 on additive manufacturing technologies.

Great people in every way, deserving of the ASTM scholarships. More groups should focus on training future generations of researchers and scientists through scholarships. Individual companies and associations could really accomplish a lot by stimulating research in selected areas.
