RS Components and Allied Electronics are spurring the world’s engineers into creative combat with an invitation to pit their design skills against each other using DesignSpark Mechanical, the companies’ new free and intuitive 3D design software, co-developed with SpaceClaim. The challenge is set for engineers of all backgrounds and disciplines to create an innovative, original design that takes into account the principles of mobility, accessibility or green living as key features of the end product. The engineer responsible for the most popular design, as voted for by the DesignSpark engineering community, will receive the top prize of £5,000 and the first ever Ormerod 3D printer created by RepRapPro. Two runners-up will each receive a prize of £2,500. To take part in the challenge, participants need to simply download the free DesignSpark Mechanical software from www.designspark.com/mechanical, create a 3D representation of their design, and submit the final idea by uploading it to DesignShare, the collaborative project space on DesignSpark.com, where each idea will be posted and votes will be cast. All entries must be received by 17:00 GMT on November 22, 2013.
