You might want to consider new design strategies for materials that contain large amounts of nickel, such as stainless steel. Prices entered the year at very close to a record high on an inflation-adjusted basis ($22/lb). Average prices for 2006 were 63% higher than 2005. Tags may rise slightly again this year because of some supply disruptions and booming demand in China for stainless. China produced 5 million metric tons of stainless steel last year. Amazingly, about 10 million more metric tons of stainless are under construction. About two-thirds of all nickel output goes into stainless. The addition of nickel to aluminum creates a super alloy that maintains structural integrity during changes in atmospheric pressure. For that reason, they’re widely used in aircraft, another area under pressure because of Chinese expansion.
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.
