When will Airbus shift to an all-composite fuselage? Could it still happen for the A350? Those are burning questions as Boeing’s 787 Dreamliner continues to sell at a torrid pace. According to the Wall Street Journal, Boeing’s order book for the Dreamliner is moving past 600, while Airbus has less than 148 “less-firm” orders for the A350. The 787 has many advantages: it’s more fuel efficient, easier to maintain and more comfortable than A350. Airbus has been tweaking the design in an effort to catch up. A new variant, dubbed the A350XWB, will have a composite main fuselage skin on an Al/Al-Li frame. Even that could change, however, to an all-composite fuselage. Each shift pushes back the effective service dates for the flagging A350. The Dreamliner probably will have at least a five-year head start.
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.
