Aspiring designers have the chance to see their 3D-printed car designs launched down a miniature model of a ski jump and crash in the Launch Day 2013 competition due to take place at the 2013 IDSA conference, which runs from 21-24 August. Up to five designs can be entered for free until 12 August in the competition, organized by The Industrial Designers Society of America.
