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.”

UK eye surgeon Rupal Morjaria was poised to operate on a 67-year-old patient when he discovered a “blueish mass” that turned out to be 17 old, lost contact lenses that had fused together; he then recovered 10 more loose, floating lenses from her eye.
Anne Marie Morris is the Conservative Party MP for Newton Abbott, Devon; while on a panel at a Eurosceptic meeting in Central London, she described the UK leaving the EU without a deal as a “real n*****r in the woodpile,” a phrase that refers to enslaved Africans and African-Americans hiding from vengeful bounty hunters after […]
Any time a trader at Enstar Capital’s new London Soho offices fancies sushi and Champagne delivered to their desk, they can press a dedicated “Champagne” button that’s being installed at each workplace, as a kind of grotesque, guillotine-inspiring homage to Amazon’s Dash button, which lets mere mortals order laundry detergent.
