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.
HP revealed more of its 3D printing plans in a recent webinar. Senior vice president of inkjet and graphics solution business Stephen Nigro spoke about how the technology works and expanded on HP's vision of open collaboration to commercialize its Multi Jet Fusion 3D printing technology for end-production, and open collaboration on new materials. He also said HP will create software to help users decide when to use Multi Jet Fusion versus conventional subtractive manufacturing.
A lightweight electric urban concept car designed by several European companies weighs only 992 lb without its battery. It would have weighed 26.7 lb more if its windows were made of glass instead of the specially coated LEXAN polycarbonate resin from SABIC Innovative Plastics.
Skylar Tibbits' team in MIT's Self-Assembly Lab is now 4D printing self-assembling shapes made of programmable carbon composites and custom wood grain. The composites are being used in a sport car airfoil, and the wood grain is beautiful.
The NanoSteel Company has produced high-hardness ferrous metal matrix composite (MMC) parts using a new nanosteel powder in a one-step 3D-printing process. Parts are 99.9% dense, crack-free, and with wear resistance comparable to M2 tool steels.
