Printing an aircraft of July 2011:

From the article:

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.


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.
