Fabrication of black body grids by thick film printing for quantitative neutron imaging

June 8, 2022
Author(s)
Martin Wissink, Kirk Goldenberger, Luke Ferguson, Yuxuan Zhang, Hassina Bilheux, Jacob LaManna, David Jacobson, Michael Kass, Charles Finney, Jonathan Willocks
Neutron imaging offers deep penetration through many high-Z materials while also having high sensitivity to certain low-Z isotopes such as 1H, 6Li, and 10B. This unique combination of properties has made neutron imaging an attractive tool for a wide range

Surface Feature Characteristics of Laser Powder Bed Fusion of Nickel Super Alloy 625 Bulk Regions

June 1, 2022
Author(s)
Jason Fox, Romaine Isaacs, Aarush Sood, Paul Brackman, Brigid Mullany, Edward Morse, Angela Allen, Edson Santos, Christopher Evans
Coherence scanning interferometry (CSI) and scanning electron microscopy (SEM) surface inspection of additively manufactured nickel super alloy 625 reveal features over a broad range of length scales beyond those typically reported. High resolution

Print Fidelity Metrics for Additive Manufacturing of Cement-based Materials

March 24, 2022
Author(s)
Edward Garboczi, Newell Moser, Joseph Biernacki, Hajar Afarani, Ebrahim Esfahani
Additively manufactured cement-based structures for infrastructure applications suffer from in-construction shape deformations, which are a strong function of process conditions and the rheology of the printing material (cement paste, mortar, or concrete)

Novel or Improved NDE Inspection Capabilities for Additively Manufactured Parts

February 26, 2022
Author(s)
Ward L. Johnson, Anne-Francoise Obaton, Alex Van den Bossch, Bryan Butsch, Imane Zouggarh, Olivier Burnet, Florent Soulard
Additive manufacturing (AM) enables the production of parts with extremely complex shapes, such as lattice structures and internal structures (cavities, channels). As a result of this geometric complexity, the applicability of most conventional

Laser Spot Welding of Additive Manufactured 304L Stainless Steel

February 1, 2022
Author(s)
Brian Simonds, Cheryl Hawk, Stephen Liu, Daniel Javernick, Robin Pacheco, Michael Brand, Jack R. Tanner, Greg Vigil
The goal of this work is to understand if an additively manufactured 304L stainless steel exhibited similar spot welding behavior as wrought 304L stainless steel. Due to the many differences between an additively manufactured component and wrought product

Interface History on Strain Field Evolution in Epoxy Resins

January 21, 2022
Author(s)
Edward Garboczi, Newell Moser, Jena McCollum, Jared Strutton, Abby Jennings, Brandon Runnels
To determine the viability of digital image correlation in the analysis of additively manufactured thermosets, we devised a testing method to examine the effect of interface history (i.e., time between interface formation and original material deposition)
