One printed for the roadONE of the great advantages of 3D printing is being able to escape the constraints of traditional production processes, and to make things with unique shapes. The powerful computer-aided design programs that are used to run 3D printers help engineers achieve this. Algorithms calculate the most efficient structure required to achieve the lightest weight and yet still handle all the loads and stresses that will be placed upon the object. Often the result is rather like something that nature might come up with—which is hardly surprising as nature has had millions of years of practice in creating highly efficient structures.
The latest example of this bionic design trend is the Light Rider, which is claimed to be the world’s first 3D-printed motorcycle. The substantial part of its structure was printed by APWorks, a company based near Munich, using a proprietary material called Scalmalloy, an aluminium-magnesium-scandium alloy that was specially developed for 3D printing by Airbus, a European aerospace group that owns APWorks.
The motorcycle is driven by a 6kW electric motor and battery. It...Continue reading
