Solidification during fusion-based additive manufacturing (AM) is characterized by high solidification velocities and high thermal gradients, two factors that control the solidification mode of AM metals and alloys. Using two synchrotron-based, in situ

Smart manufacturing (SM) systems utilize run-time data to improve productivity via intelligent decision-making and analysis mechanisms on both machine and system levels. The increased adoption of cyber-physical systems in SM leads to the comprehensive
Industrial users of ISO 10303 STandard for the Exchange of Product Model Data (STEP) protocols needed the ability to exchange design product data that is in conformance with recently updated ISO geometric product specification (GPS) standards, the American

In additive manufacturing, the part quality is highly dependent on process parameters. The morphology of the melt pool (depth and width) is highly affected by process parameter selection. Available scaling laws more or less overestimate or underestimate
Current maintenance research often includes modeling the equipment degradation to determine degradation and in particular, when any degradation will exceed a specified threshold. Such models can provide critical intelligence to determine an impending
The production and consumption of textile products traditionally follows a largely linear (take, make, use, discard) economic model. Textiles are currently being produced in greater volumes than ever before, even after accounting for population growth, and

The National Institute of Standards and Technology is developing performance tests and associated test artifacts as a means to benchmark research in the area of robotic assembly. Sets of components consistent with mechanical assemblies including screws
Additive manufacturing (AM) is a powerful technology that can create complex metallic parts and has the potential to improve the economic bottom line for various industries. However, due to process instabilities, and the resulting material defects that
There remains a need for rheological characterization of metal powder used for powder-spreading-based additive manufacturing (AM). Novel powder rheometers introduced to the commercial market for this purpose must be rigorously evaluated for repeatability
With the advancement of factory logistics into the autonomous era comes the need to validate the safety and performance characteristics of Autonomous-Unmanned Ground Vehicles (A-UGVs) working in these application spaces ASTM Committee F45 has been

The use of engineered cells, tissues, and organs has the opportunity to change the way injuries and diseases are treated. Commercialization of these groundbreaking technologies has been limited in part by the complex and costly nature of their manufacture
The effect of the scan strategy on internal porosity is investigated on a custom-built laser powder bed fusion additive manufacturing testbed. Two different scan strategies are compared: constant laser power and constant laser power density. The constant
Currently, global economies are using resources and contaminating resources faster than they can be regenerated. This resource depletion strains the economy and society today and into the future and is largely due to a series of misaligned incentives
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
Manufacturing USA® is a network of public-private partnerships united to secure U.S. global leadership in advanced manufacturing through large scale collaboration on technology, supply chain, and workforce development. The network includes the U.S
The proliferation of electronics, batteries, and solar panels in recent decades has resulted in a substantial generation of end-of-life (EoL) "high-tech" products. Currently, these products follow a largely linear – extract, make, use, dispose – model, but

With increased use of exoskeletons in a variety of fields such as industry, military, and health care, there is a need for measurement standards to understand the effects of exoskeletons on human motion. Optical tracking systems are the current gold
Industrial users can be justifiably hesitant in adopting Condition Monitoring Systems (CMSs) unless evidence indicates benefits from their use. Measuring a CMS's ability to prevent losses is difficult and lacks standard procedures. The increasing
