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.”

Gavin Chait is an "economist, engineer, data scientist and author" who created a website called Pikhaya where UK entrepreneurs can get lists of vacant commercial properties, their advertised rents, and the history of the businesses that had previously been located in those spaces -- whether they thrived, grew and moved on, or went bust (maybe […]
Official UK government statistics reveal that on 30 days in July the Border Force agency at Heathrow failed to meet its target of processing visitors within 45 minutes; on July 5, visitors had to wait 2.5 hours.
The UK Committees of Advertising Practice changed the rules for ISP advertising: where once the ISPs could advertise speeds of "Up to" some incredibly high number so long as 10% of customers ever achieved that speed, now ISPs can only advertise a speed promise if 51% of their customers attain that speed at all times.
