Rapid Manufacturing: Not Just for Prototypes

Prototyping processes such as 3D printing, CNC machining and forms of injection molding have been known to produce great prototypes in low quantities. The perception of these processes known as Rapid Manufacturing is that they are only valuable for prototyping.

Hollow-Core Optical Fiber

Confining light to an air core fiber is not easily done using traditional guidance methods such as total internal reflection. In this presentation we demonstrate guidance in air using photonic band gap guidance and anti-resonant rings. Single-mode hollow-core optical fibers with large cores, resulting in low loss are shown. We also present the attenuation dependence in these fibers and how, using fibers that guide light in air, we are able extend the wavelength range of silica fibers out to the infra-red.

Stevan Spremo, Project Manager, COTSAT-1, Ames Research Center, Moffett Field, CA

Stevan Spremo is the project manager of COTSAT-1, or Cost Optimized Test of Spacecraft Avionics and Technologies. The ongoing development project aims to build a fully functional spacecraft for $500,000 in parts and $2 million labor. The prototype is the first of what could be a series of rapidly produced, low-cost flight vehicles.

Dr. Patrick Fink, Chief Technologist, Wireless Communication Systems Branch, Johnson Space Center, Houston, TX

Dr. Patrick Fink leads technology development of radio frequency identification (RFID) systems. The RFID technology will support NASA’s efforts to track its various inventories on the International Space Station, from personal supplies to equipment components. A new smart container innovation tracks individual items, regardless of placement.

Joe Munchak, Research Meteorologist, Goddard Space Flight Center, Greenbelt, MD

Using the Global Precipitation Measurement (GPM) Core Observatory satellite, launched in 2014, NASA and Japan Aerospace Exploration Agency researchers have taken the first 3D images of raindrops and snowflakes. The GPM snapshots will help research meteorologist Joe Munchak determine precipitation rates and support the improvement of weather models.

John Hanson, Nodes Deputy Project Manager and Technical Lead, NASA Ames Research Center, Moffett Field, CA

On December 6, 2015, two CubeSats successfully launched to the International Space Station. As part of NASA’s Nodes mission, the CubeSats will soon communicate with each other and demonstrate the benefits of a networked "swarm" of spacecraft.
