3D Hybrid Metal Prototyping Device
A new hybrid, 3D, Metal, Prototyping Device combines welding technology, instead of laser sintering of a metal powder, with a subtractive/machining process (Computer Numerical Controlled Machining - CNC) to create metal parts with unmatched complexity, precision, and quality. The device has a low, initial machine cost and a low build cost, using welding wire instead of metal powder, allowing for inexpensive, large lot production of fully functional metal parts. It has complete access to all surfaces of the metal part as each layer is welded/built. This improves machining performance and part tolerances. In addition, the rotational speed of the CNC machining is slower, reducing device downtime and maintenance costs.

Aerial Refueling Hose-Drogue Simulation Program
     Probe-drogue refueling (PDR) involves coupling a probe on a receiver aircraft with a probe receptacle (drogue) attached to a flexible, fuel hose from a tanker aircraft.  PDR has always been a technically challenging operation and improvements to PDR systems to ensure overall safety for both manned and unmanned vehicles are urgently needed. A software program is available that permits testing of designs for PDR before and during prototype development by simulating and predicting all of the movements of hose-drogue refueling systems during aircraft refueling maneuvers.

Barrier Coatings Impervious to Water, Oil and Grease
     Barrier coatings have been developed utilizing commercially available nanoparticle constituents that permit coating of almost any material and provide superior protection from penetration by water, oil and grease. The coatings are water based, easy to apply and dry, and are environmentally friendly.

HVAC Evaporative Pads with Chitosan
A new HVAC-Evaporative Pad that can be used for agricultural and other HVAC applications has been developed by applying a chitosan coating to paperboard in place of phenol resins and other non-green coatings. These evaporative pads have a single layer of chitosan that creates a lighter pad with better wet stiffness, wicking height and water absorption, providing improved evaporative cooling. The manufacturing process is simple, inexpensive, environment-friendly and the paperboard is completely recyclable.

Low Cost, Flexible, Microfluidic System
     A microfluidic device has been developed that is  easy (no clean room) to manufacture and is made from a flexible material that avoids breakage. The Microfluidic System can be configured to perform multiple functions, which are common to microfluidic devices, while being low cost for disposable applications.

Micro Laser Assisted Machining Device, Micro-LAM
     Machines semiconductor and ceramic materials by simultaneously heating and deforming the microscopic area of the material that is in contact with the tool tip. The Micro-LAM delivers greater machining precision and a faster machining rate than conventional LAM, while being non-damaging (minimal heating), and providing greater energy efficiency, and reduced down time.

Patternless, Rapid, Sand Mold Prototyping for Casting
      This device and method quickly creates accurate sand molds and cores for casting using a hybrid approach of 3D layering and CNC machining of each sintered layer. It employs a resin coated, black carbon, shell sand that is easily sintered with visible light and that acts as a lubricant for rapid CNC machining of each layer after the layer is sintered. In addition, the sand resin is not flammable, allowing starting materials, and completed molds and cores to be safely stored and transported.
