What do US military planners consider top materials research targets? Well according to the head of the Pentagon’s research arm (the Defense Advanced Research Projects Agency or DARPA) low-cost titanium tops the list. Titanium is in increasing demand for light weight aircraft and stealth-seeking submarines, while its costs are rising and significant amounts of supply are controlled by Russia. One troubling indication is the recent huge supply agreement made between Boeing and Russia’s top titanium provider. DARPA has distributed more than $20 million in grants in efforts to develop lower-cost titanium, as well as material that would have improved fabrication capabilities. DuPont is teaming with a company called MER to explore a technology in which titanium dioxide can be converted into titanium power which can be easily shaped through molding or casting processes.
A new service lets engineers and orthopedic surgeons design and 3D print highly accurate, patient-specific, orthopedic medical implants made of metal -- without owning a 3D printer. Using free, downloadable software, users can import ASCII and binary .STL files, design the implant, and send an encrypted design file to a third-party manufacturer.
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.
