Coming Soon - Advances in Metal Additive Manufacturing -- the Development and Applications of Electron Beam Freeform Fabrication (EBF3)

Metal additive manufacturing, also called “3D printing,” has blossomed over the past decade, growing from a novelty research area to commercial systems used in a variety of small-scale production applications. Electron beam freeform fabrication (EBF3) is an additive manufacturing process that builds three-dimensional metal parts layer-by-layer using wire feedstock and an electron beam heat source. Researchers at NASA’s Langley Research Center initiated development of EBF3 to address challenges in applying metal additive manufacturing to large-scale structural aircraft components, launch vehicles, and in-space manufacturing for building tools, spares and replacement parts for use in space. This webcast will discuss the maturation of the EBF3 technology from inception to commercialization and will describe some of NASA’s current and emerging applications of this additive manufacturing technology.

Coming Soon - Using Novel Flash Infrared Thermography Techniques and Software

Researchers at NASA’s Johnson Space Center (JSC) have developed an infrared (IR) flash thermography software program that is capable of detecting and characterizing anomalies, such as voids, cracks, and delamination, in nonmetallic structures with higher fidelity and sensitivity than other available techniques. Using an innovative IR contrast methodology, this software extracts normalized contrast versus time evolutions from flash thermography IR video data to accurately measure flaw depth, width, and diameter.

Coming Soon - The Stealth E-Bike: Challenges in Developing the First Fully Integrated Drive System for E-Bikes

Developing an E-Bike that looks and drives like a conventional bike raises significant engineering challenges. Yet this is what the team at FAZUA has achieved with their proof-of-concept bike, using electrical assistance from their evation drive system. The drive system, containing all engine components like engine, electronics and battery, is placed in the downtube of a bike and can be removed by just one click at any time. Within seconds, an e-bike is converted into a lightweight bike as a bezel is put at its place. The next generation prototype, which will attain a pre-series status, is currently in development with the aid of CAD construction and simulation software.
