Like it or not, design engineers need to get prepared for more environmentally oriented requirements. The newest evidence is an executive order from President George W. Bush that ramps by green requirements for the federal government. One of the six parts of the new order requires federal agencies to improve energy efficiency and reduce greenhouse gas emissions 3% annually through the end of fiscal year 2015. President Bush also wants agency acquisitions to reflect sustainable environmental practices, including acquisition of biobased, environmentally preferable, energy-efficient, water-efficient, and recycled-content products, and use of paper of at least 30% post-consumer fiber content. The requirement on bio-based materials is interesting. Design News plans to look intensively at the potential of bio-based polymers for engineering applications in the April 30 issue. Stay tuned.
Norway-based additive manufacturing company Norsk Titanium is building what it says is the first industrial-scale 3D printing plant in the world for making aerospace-grade metal components. The New York state plant will produce 400 metric tons each year of aerospace-grade, structural titanium parts.
Siemens and Fraunhofer Institute for Laser Technology have achieved a faster production process based on selective laser melting for speeding up the prototyping of big, complex metal parts in gas turbine engines.
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
SABIC's lightweighting polycarbonate glazing materials have appeared for the first time in a production car: the rear quarter window of Toyota's special edition 86 GRMN sports car, where they're saving 50% of its weight compared to conventional glass.
