Plastic pinion for engine tuning
The Formula Student Team from Weingarten near Ravensburg needed, among other things, customised plastic pinions to construct their racing cars. The pinions were used as chain tensioners in the chain drive, so they had to be especially robust. Unfortunately, pinions in special sizes have long delivery times, and classic production by means of milling is time-consuming. The igus® 3D printing service allowed plastic pinions to be delivered and tested in less than 72 hours. The material used was iglidur® I6, which is especially wear-resistant – it was still fully functional after one million cycles in laboratory tests – and was thus ideal for use in racing cars. In this case, the special parts from additive manufacture were not only available much faster, but were more robust and economical.
