Any type of government management of the car industry is a bad idea. One proof of that is the Trabant, a “car” produced in East Germany before the fall of the Berlin Wall. To start with, the vehicle was made from plastic composite, no not the type of high-tech thermoplastic material envisioned for the hood of the Chevy Volt concept car or the carbon composite hood used in the Corvette ZR1. The Trabant’s composite was called Duroplast, a thermoset resin reinforced with cotton waste from Russia. It couldn’t be recycled and when it burned the material produced toxic residue. Paper was also at times used as a reinforcing material for the phenolic waste matrix material, leading to the erroneous suggestion that the Trabant’s body was made from cardboard. Duroplast was the best part of the Trabant, which was made by VEB Sachsenring Automobilwerke Zwickau. One reviewer commented: “Ostensibly, there’s not a whole lot to love about a car that creaks like an out-of-warranty pirate ship and spews more smoke than a Winston Churchill-Fidel Castro summit.” The car cost a comrade a year’s salary and some buyers had to wait as long as 15 years for a delivery. The Trabant–a car made in a Socialist system– is one of the reasons why I don’t want the federal government to get involved in the car industry – in any way, shape or form.
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.
