Spray-formed tooling is a new approach for the making of stamping
dies and molds. The new rapid-tooling process involves spraying molten steel
over ceramic casts, which eliminates machining and other processing steps. Ford
is using spray-formed tooling for making torque-converter blade dies for
lift-gate brackets, wiper-motor brackets, instrument brackets, and inner-hood
reinforcements. "The spray-formed tooling process will shave millions of dollars
and several months off of the production process," says Dr. Charles Wu, director
of the Ford Manufacturing Systems and Vehicle Design Research Laboratory. The
technology is an all-inclusive rapid-tooling process that includes die
development, design, and construction. Envelope size for the initial dies was 1
sq ft, but the size is expected to grow to 8 x 8 ft. For more information,

A Tokyo company, Miraisens Inc., has unveiled a device that allows users to move virtual 3D objects around and "feel" them via a vibration sensor. The device has many applications within the gaming, medical, and 3D-printing industries.
In the last few years, use of CFD in building design has increased manifolds. Computational
fluid dynamics is effective in analyzing the flow and thermal properties of air within spaces. It can be used in buildings to find the best measures for comfortable temperature at low energy use.
