Additive Manufacturing Part Qualification

Completed
Objective To develop and deploy test methods and protocols, standard test artifacts, exemplar data, data processing tools, and automation tools that create robust post-process measurements and non-destructive testing to enable qualification of AM parts by manufacturers. What is the Problem? To

Autonomous Scanning Droplet Cell

Ongoing
Corrosion impacts a broad spectrum of application areas including infrastructure, transportation, and the military. The annual price tag for corrosion mitigation and remediation is 3.4 % of the US GDP. The team is particularly interested in discovering new metallic glasses (metals without long range

Consistency Analysis and Uncertainty in ‘omic Data

Ongoing
‘Omics is increasingly moving out of the laboratory and towards use in industrial and commercial applications. For instance, in biomanufacturing, there is a need for quality control when developing biotherapeutics, which will almost certainly require a machine-learning classifier to separate

Data Driven Decision Support for Additive Manufacturing

Completed
Objective To develop and deploy the metrics, models, and best practices for using product definition, advanced analytics, and machine learning methods in additive manufacturing design and process planning to reduce lead times and support first-part-correct goals. Technical Idea Future advancements

Data Integration and Management for Additive Manufacturing

Completed
Objective Data plays the most critical role in linking AM lifecycle and value chain activities and streamlining the AM development process. While the AM data from a single build is essential for establishing part traceability, when methodically collected, the full processing history of thousands of

Detecting Change Points in Surface Temperature Records

Ongoing
DESCRIPTION: For the purpose of exposition, consider the record daily minimums averaged by month for a station near Reno Nevada. There is a clear drop in the level between 1920 and 1940 and a positive drift starting at about 1980. There is also however, considerable variability due to seasonal

Material Qualification

Ongoing
Objective To develop, utilize, and analyze methods of characterizing the precursor materials in additive manufacturing in both virgin and recycled states with the goal of advancing measurement science to benefit the AM community. The components of principal interest will include the rheological

metRology for Microsoft Excel

Ongoing
DESCRIPTION: The current version of the metRology for Microsoft Excel add-in focuses on uncertainty analysis using the methods outlined in the JCGM Guide the Expression of Uncertainty in Measurement (often referred to as the GUM). These methods for uncertainty analysis are widely accepted and their

Metrology for Multi-Physics AM Model Validation

Completed
Objective To provide reference data for the validation of multi-physics models of metal additive manufacturing processes to enable improvement of AM process models and more rapid and predictable process development for AM production by manufacturers. What is the Technical Idea? The Metrology for

metRology Software Project

Ongoing
DESCRIPTION: The current version of the metRology package focuses on statistical functions for uncertainty analysis and for the analysis of interlaboratory studies and key comparisons. A number of the functions focus on uncertainty analysis using the methods outlined in the JCGM Guide to the

NIST PS1 Primary Standard for quantitative NMR (Benzoic Acid)

Completed
With explicit SI linkage, the overall impact of this apical reference material is profound—this primary standard, as well as forthcoming members of its class, provides technology transfer of chemical purity realization to the commercial sector for characterization of many thousands of organic

Precursor Material Qualification

Completed
To develop, utilize, and analyze methods of characterizing the precursor materials in additive manufacturing in both virgin and recycled states with the goal of advancing measurement science to benefit the AM community. The components of principal interest will include the rheological, size

Qualification for AM Feedstocks, Machines and Processes

Completed
Objective - To develop, utilize, and analyze test methods and protocols for characterizing the feedstocks, machines, and processes in metal-based additive manufacturing to enable optimum usage and to reduce the cost and time needed for qualification. What is the Technical Idea? Qualification of AM

Quantifying Uncertainty in Accelerometer Sensitivity Studies

Ongoing
DESCRIPTION: International Key Comparisons are performed. The key comparison reference value for charge sensitivity as a function of frequency and the accompanying uncertainty are the principal objectives of these studies. In a suggested mixed effects model several methods for evaluation of this

Sensing and Imaging of concealed objects

Ongoing
Threats to personal and collective safety abound in our society. The Security Technologies Group (STG) performs research to advance the technology and measurement science of security imaging and sensing. This work includes the establishment of test and evaluation tools, reference test beds, test

Standards Development to Ensure Reliable Breath Analysis in the Field

Ongoing
Numerous volatile organic compounds (VOCs) have been identified in human breath. These compounds can be produced by the body or by organisms in the body (e.g., bacteria or viruses) and provide a non-invasive window into human health. Inexpensive point-of-care devices are being developed to diagnose
