UAV airframe printed from polyamide


An all-polyamide laser sintered unmanned aerial vehicle (UAV) comprises just five structural/aerodynamic components. The entire structure, including wings, integral control surfaces and access hatches, was fabricated on an EOS EOSINT P730 nylon laser sintering machine from EOS GmbH (Munich, Germany).

The Sulsa (Southampton University Laser Sintered Aircraft) was designed by engineers at the University of Southampton in the UK and fabricated with the assistance of 3T RPD (Newbury, UK). Instead of fasteners, solely snap-fit methods are employed to install all avionics, payload and propulsion components. Further, hinges and moving parts are printed in place.

The resulting aircraft can be fully assembled from its component parts to flight ready in just 10 minutes without the use of any tools whatsoever....
