Circular Economy in the High-Tech World Workshop Report

December 14, 2021
Author(s)
Martin L. Green, Kelsea Schumacher
The National Institute of Standards and Technology (NIST) held a Technical Workshop on January 27 and 28, 2021 to assess the state and challenges of a Circular Economy (CE) in the High-Tech World. Scientists, researchers, and program managers in the CE

Experiments to Test the A-UGV Capabilities Standard

December 8, 2021
Author(s)
Soocheol Yoon, Roger V. Bostelman, Ann Virts
Automatic, Automated, or Autonomous - Unmanned Ground Vehicles (A-UGVs), as referred to by ASTM International Committee F45, are industrial vehicles that have capabilities to navigate, dock, avoid obstacles, and interact with other vehicles and systems all

A Data Integration Framework for Additive Manufacturing Big Data Management

December 7, 2021
Author(s)
Milica Perisic, Dimitrije Milenkovic, Yan Lu, Albert T. Jones, Nenad Ivezic, Boonserm Kulvatunyou
Large amounts of data are generated throughout the entire, AM, part-development lifecycle. Data are generated by various functions within process monitoring, material characterization, equipment status, and part qualification. Hence, data integration and

Sintered powder oxidation variation as a function of build height for titanium alloy produced by electron beam powder-bed fusion

November 26, 2021
Author(s)
Nicholas Derimow, Alejandro Romero, Aldo Rubio, Cesar Terrazas, Francisco Medina, Ryan Wicker, Nik Hrabe
It is well-established that titanium alloy (Ti-6Al-4V) powder oxidizes during electron beam powder-bed fusion (PBF-EB) due to the high background temperatures resulting from layer preheating and sintering of the powder bed before melting. However, it is

A Comparison of Particle Size Distribution and Morphology Data acquired using Lab-based and Commercially Available Techniques: Application to Stainless Steel Powder

November 17, 2021
Author(s)
Justin Whiting, Edward Garboczi, Vipin Tondare, John Henry J. Scott, Alkan Donmez, Shawn P. Moylan
The particle size distribution (PSD) and particlemorphology ofmetal powders undoubtedly affects the quality of parts produced by additivemanufacturing (AM). It is, therefore, crucial to accurately knowthe PSD and morphology of these powders. There exist

Evaluation of a Modified Void Descriptor Function to Uniquely Characterize Pore Networks and Predict Fracture Location in Additively Manufactured Metals

November 15, 2021
Author(s)
Dillon Watring, Jake Benzing, Orion Kafka, Li-Anne Liew, Newell Moser, John Erickson, Nik Hrabe, Ashley Spear
Variations in additive manufacturing (AM) processing parameters can lead to variations in porosity, making it challenging to predict pore- or void-sensitive mechanical response in AM metals. A recently developed pore metric, the void descriptor function

November 5, 2021
Author(s)
Zahraha Brunner, Frank W. Gayle
A summary of technology innovation and workforce development projects by the Manufacturing USA network for FY 2020.

Annual Report on U.S. Manufacturing Industry Statistics: 2021

October 29, 2021
Author(s)
Douglas Thomas
This report provides a statistical review of the U.S. manufacturing industry. There are three aspects of U.S. manufacturing that are considered: (1) how the U.S. industry compares to other countries, (2) the trends in the domestic industry, and (3) the
