    Government Cheese... SGLB Involved in funded research project

    NIST Funding: $5.0 million (SGLB listed below)

    The National Additive Manufacturing Innovation Institute (NAMII) proposes a three-part research plan to ensure that quality parts are produced and certified for use in products made by a variety of industries and their supply chains. The emphasis is on providing tools needed for additive manufacturing applications to progress from prototype to market-ready.

    Edison Welding Institute (EWI) will lead collaborative efforts to develop in-process sensing and monitoring capabilities so that tolerances and other quality requirements are consistently achieved. EWI and its NAMII partners will focus on an additive manufacturing technology known as laser-powder bed fusion, with the goal of optimizing the structure and properties of metal powders as they are fused into parts.

    Concurrent Technologies Corp. and its NAMII partners will develop and validate nondestructive evaluation techniques for post-manufacturing inspection. Such techniques are necessary to satisfy customers that their requirements have been met with the still-emerging manufacturing technology. This is especially true for customers with orders for complex high-value-added parts, a sweet spot for additive manufacturing.

    A team led by the University of Louisville will develop and refine a “layerwise certification standard” for additive manufacturing. Building on the two other projects, this effort would yield a high-definition record of each part as it is produced in the layer-by-layer manner that is characteristic of additive manufacturing. The ultimate goal is to produce a “3D Quality Certificate” that would index in-process measurements to part geometry and properties.
