At the University of Virginia, engineers are printing airplanes.
Three-dimensional printing is the production, or “printing,” of actual objects, such as toys or parts for devices, by using a machine that traces out layers of melted plastic in specific shapes until it builds a piece to the exact specifications of a computer-aided drawing produced by a designer.
With the increased availability of user-friendly computer programs and 3-D printers, that designer can be anybody. Eventually, almost any object, or parts for objects, may become 3-D printable – even including body implants – in a range of materials, including metals.
U.Va. engineers and engineering students are using sophisticated 3-D printing technology to make an array of objects, including a plastic airplane for a Department of the Army project.
David Sheffler, a lecturer in the Department of Mechanical and Aerospace Engineering in U.Va.’s School of Engineering and Applied Science and 20-year veteran of the aerospace industry, teaches 3-D printing to engineering students. He recently took some time to discuss the future of 3-D printing in industry and society.
Q: Please explain the 3-D-printed, hand-launchable, fully autonomous, unmanned aerial vehicle named “The Razor,” on which you are working with the Mitre Corporation. It appears to be built with off-the-shelf hardware, using an Android smartphone as the central processor.
Sheffler: We were asked to help investigate the feasibility of producing a UAV with the same capabilities in speed, flight time and payload as other systems currently deployed by the military that could be 3-D-printed and utilize non-proprietary hardware for the
