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
Laser tracker calibration in Tape Tunnel Facility

Advanced Dimensional Measurement Systems

Ongoing
New dimensional measurement technologies provide significant benefits to industry such as increasing measurement throughput, enabling new manufacturing process (such as additive manufacturing) and providing more detailed part information for manufacturing process improvement. However, before

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

Diffraction Metrology and Standards

Ongoing
Diffraction techniques can provide data on a number of sample characteristics. Therefore, the method of certification and the artifact itself are chosen to address a specific measurement issue pertinent to a diffraction experiment. NIST diffraction SRMs may be divided into five groups: Line Position
Prototype NIST developed Next-Gen fiber probe for inspection of small critical features.

Dimensional Measurement Services

Ongoing
The Dimensional Measurement Services project promotes manufacturing innovation and U.S. industrial competitiveness by providing critical technology-enabling high accuracy dimensional measurements within an internationally accepted quality system. These measurements span the dimensional metrology

SI Length and Traceability

Ongoing
Laser interferometry, which measures distances in terms of light wavelength, provides the backbone of top-level length metrology in industry and science. This project develops techniques to facilitate the tie between interferometer-based length measurements and the SI definition of length (in terms

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
