Previously 3D printing techniques, or rapid prototyping, was used to built mock-up products too brittle for on-track use but with improving materials 3D printed parts become usable “in action” too. A good example is the Vizion touring car rear wing made by a company called Shapeways. U.S. on-road legend Josh Cyrul introduced the Vizon branded wings to the public with the 190mm TC wing being available as a high and medium downforce version, both greatly improve the overall grip and stability of car. The wing comes white and in a slightly grainy finish and it has to be painted not only to match the body’s colour but also to make for more flexibility and durability as the porous material soaks up the paint. We understand that more Vizon products will surface very soon with several 1/12th scale rims and option parts being in the making.
