Engineers at the University of Southampton have designed and flown the world’s first ‘printed’ aircraft, which could revolutionise the economics of aircraft design. The SULSA (Southampton University Laser Sintered Aircraft) plane is an unmanned air vehicle (UAV) whose entire structure has been printed, including wings, integral control surfaces and access hatches. It was printed on an EOS EOSINT P730 nylon laser sintering machine, which fabricates plastic or metal objects, building up the item layer by layer. No fasteners were used and all equipment was attached using ‘snap fit’ techniques so that the entire aircraft can be put together without tools in minutes. The electric-powered aircraft, with a 2-metres wingspan, has a top speed of nearly 100 miles per hour, but when in cruise mode is almost silent. The aircraft is also equipped with a miniature autopilot developed by Dr Matt Bennett, one of the members of the team. Laser sintering allows the designer to create shapes and structures that would normally involve costly traditional manufacturing techniques. This technology allows a highly-tailored aircraft to be developed from concept to first flight in days. Using conventional materials and manufacturing techniques, such as composites, this would normally take months. Furthermore, because no tooling is required for manufacture, radical changes to the shape and scale of the aircraft can be made with no extra cost.

Sounds incredible!

I wonder how much of it was actually "printed"? Motor, control servos, electronics, batteries... probably not.
Obama's watch stopped on 24 May 2008, but he's been too busy smoking crack to notice.
Just about everything but the motor and batteries. Here's another article with some pictures. "...all of the equations in neoclassical economics are rubbish. The differential equations describe nothing. Economics is not about mathematics, it is about the human being." Sandeep Jaitly

Way cool... Ok, I *gotta'* ask the question... How did you FIND this article?
It used to be the leftists that had bumper-stickers that said things like "Question Authority.' Today they follow slogans from 1984: War is peace. They blindly LOVE Big Brother. They believe competition, pride & profiting from ones labor, are evil things to be banished. Stephen King observed, "The beauty of religion mania is that it has the power to explain everything... [so] logic can be happily tossed out the window. This describes socialists. They will ignore logic and "common sense." They will ignore REALITY. Because THEY are religious zealots... THEIR God... is the STATE.
I looked for it. How do you find things?

Professor Keane adds: “Another design benefit that laser sintering provides is the use of an elliptical wing planform. Aerodynamicists have, for decades, known that elliptical wings offer drag benefits. The Spitfire wing was recognised as an extremely efficient design but it was notoriously difficult and expensive to manufacture. Again laser sintering removes the manufacturing constraint associated with shape complexity and in the SULSA aircraft there is no cost penalty in using an elliptical shape.”
