Last July, engineers from the UK's University of Southampton have flown an unmanned air vehicle whose chassis was entirely constructed of parts that came off a 3D printer; the parts were designed to snap-fit and the plane can be assembled without tools.
Professor Scanlan says: “The flexibility of the laser sintering process allows the design team to re-visit historical techniques and ideas that would have been prohibitively expensive using conventional manufacturing. One of these ideas involves the use of a Geodetic structure. This type of structure was initially developed by Barnes Wallis and famously used on the Vickers Wellington bomber which first flew in 1936. This form of structure is very stiff and lightweight, but very complex. If it was manufactured conventionally it would require a large number of individually tailored parts that would have to be bonded or fastened at great expense.”
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.”

The internets will tell you that spraypainting a giant penis around a pothole will get your town’s roadworks to prioritize its repair. The internets are wrong.
The UK Supreme Court recently ruled in MM v SSHD, finding that the UK government could legitimately deny entry to a British citizen’s spouse if the citizen didn’t have enough money to support them. This same policy is the reason that parents of 15,000 British children are not allowed to live in the UK with […]
Under a new proposal from the UK Law Commission, journalists who handle or report on leaked documents demonstrating corruption or government malfeasance would face prison sentences.
When you can’t wait for the world’s longest meeting to end, the mindless leg bouncing makes your boredom obvious and just annoys everybody else.

You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
