3D-Printed UAV Can Go From Atoms to Airborne in 24 Hours

Posted by timothy on from the concept-and-model-in-one dept.

Zothecula (1870348) writes "Because 3D printing allows one-off items to be created quickly and cheaply, it should come as no surprise that the technology has already been used to produce unmanned aerial vehicles, or UAVs. Engineers at the University of Sheffield's Advanced Manufacturing Research Center (AMRC), however, have taken things a step farther. They've made a 3D-printed UAV airframe that's designed to minimize the amount of material needed in its construction, and that can be printed and in the air within a single day."

A linear motor is a magnet inside a coil. A few wraps of conductor will do for the coil. For a radial motor you need many more fine conductors wrapped close together to work. Then there is the issue of bearings which have to be smooth enough to handle a few hundred RPM for a significant period of time. A speaker has one moving part suspended by the cone. The tolerances alone make radial motors much more complex than linear motors. A radial motor coil is much harder to print than a speaker.
