The 2023 National Institute of Standards and Technology Environmental Scan provides an analysis of key external factors that could impact NIST and the fulfillment of its mission in coming years. The analyses were conducted through three separate lenses
This is the report of a hybrid working group meeting held on April 25, 2023, at the National Institute of Standards and Technology (NIST) in Boulder, CO. The working group was focused on extreme ultraviolet lithography (EUVL) research, development, and
In the Laser Powder Bed Fusion (LPBF) additive manufacturing (AM) process, a high-speed scanning laser beam is employed to construct components by melting and fusing metal powder together. While AM is generally characterized as a layer-by-layer technique

A successful transition to a circular economy (CE) will require global participation, but the path to that transition will follow many unique routes depending on local situations. The transition must have rigorous technical underpinnings and well-conceived
This report estimates biomanufacturing (manufactured products made of biomaterials) and advanced biomanufacturing (products manufactured using activities that grow biological molecules and materials along with activities that alter biological material

ISO has recently issued a series of standards (ISO 23247) that deals with a digital twin framework for manufacturing. It is a generic framework that can be specialized to enterprises engaged in different manufacturing processes, such as discrete, batch, or
Thermoset composites are excellent candidates for material extrusion because they shear thin during extrusion but retain their shape once deposited via a yield stress. However, thermal post-curing is often required to solidify these materials, which can
Data formats play an integral role in leveraging the flexibility of additive manufacturing and achieving consistent part quality. This article compares and contrasts data formats optimized for design, materials, processes, and inspection methods. It also
