A metal/polymer hybrid featuring nanotechnology aimed at extremely lightweight components was introduced at K 2007 today by DuPont Engineering Polymers and partners Morph Technologies of Toronto, Canada; Integran Technologies, of Pittsburgh, PA; and PowderMetal Technologies of Carlsbad, CA. Key to the technology is a new proprietary process called MetalFuse that applies precise amounts of nanometal to molded plastic components. Parts are said to have the stiffness of aluminum or magnesium but with better strength. Grain sizes of the metals are 1000 times smaller than conventional metals. “Nanocrystalline nickel or nickel-iron are high-performance metals that are two to three times stronger than normal steel and are also significantly harder, with better wear and friction performance,” says Gino Palumbo, president of Integran Tehcnologies. Initial development will focus on selected applications in the automotive, consumer electronics, and sporting goods markets.
A recent report sponsored by the American Chemistry Council (ACC) focuses on emerging gasification technologies for converting waste into energy and fuel on a large scale and saving it from the landfill. Some of that waste includes non-recycled plastic.
Capping a 30-year quest, GE Aviation has broken ground on the first high-volume factory for producing commercial jet engine components from ceramic matrix composites. The plant will produce high-pressure turbine shrouds for the LEAP Turbofan engine.
Seismic shifts in 3D printing materials include an optimization method that reduces the material needed to print an object by 85 percent, research designed to create new, stronger materials, and a new ASTM standard for their mechanical properties.
A recent study finds that 3D printing is both cheaper and greener than traditional factory-based mass manufacturing and distribution. At least, it's true for making consumer plastic products on open-source, low-cost RepRap printers.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
