3D-Printed Functional Antenna Arrays Operate on Exterior of COSMIC-2 Satellites

FDM® (Fused Deposition Modeling™) technology and ULTEM 9085 thermoplastic Stratasys Direct Manufacturing (RedEye, Solid Concepts, and Harvest Technologies) Eden Prairie, MN 866-882-6934 www.redeyeondemand.com In 2006, a satellite mission called the Constellation Observing System for Meteorology, Ionosphere, and Climate (COSMIC-1) was put into orbit. The purpose of the instrument was to collect global ionospheric and atmospheric data of temperature, moisture, and pressure, including hard-to-sample areas such as above oceans and polar regions. The project was led by the University Corporation for Atmospheric Research (UCAR), a consortium of more than 70 research universities in the US, and Meteorological Society of the Republic of China (Taiwan). Since its inception, the COSMIC-1 project has contributed to a wide range of scientific investigations and improvements in weather forecasting.

Process to Fabricate Specific Sized Monodisperse Polystyrene Microparticles

Langley Research Center, Hampton, Virginia A new method was developed to prepare monodisperse nano to microparticles of polystyrene ranging from 0.5 to 2.5 microns in relatively large-quantity batches (2 L, 10% by weight in water). Current commercial sources are very expensive and can typically only be acquired on a relatively small scale. Monodisperse polystyrene in this size range is an important component of laser velocimetry measurements in wind tunnels, but has many other potential uses. Polystyrene microparticles have uses in paints/coatings, adhesives, bio/immunoassays, reaction catalysts, and chromatography materials. The main benefits of this technology are low cost, scalability, and selectable size.

Atmospheric Pressure Plasma-Based Fabrication of Printable Electronics and Functional Coatings

Applications include biomedical, consumer electronics, security, and communications industries. Ames Research Center, Moffett Field, California The need for low-cost and environmentally friendly processes for fabricating printable electronics and biosensor chips is growing. Nanomaterials have proved to be very useful in both printable electronics due to their electronic properties, and in biosensors for signal transduction, and amplification. Chemical vapor deposition requires high temperatures for the growth of nanostructures, restricting the type and nature of materials that can be used as substrates. Conventional plasma-enhanced chemical vapor deposition requires high vacuum equipment, and the need for vacuum results in additional costs of vacuum pumps and energy resources.

Passive Destructive Interference Acoustic Liner for a Turbofan Engine Using Additive Manufacturing

John H. Glenn Research Center, Cleveland, Ohio This technology exploits the capabilities of additive manufacturing to attenuate the fan noise within the inlet or aft duct of a turbofan engine. The approach may be expanded to include auxiliary power units, environmental control systems, or other cooling systems requiring noise attenuation.
