iMakr's Verdict Tribology is the study of friction and governs the design of bearings and wear resistant parts. Igus specialise in the production of polymer bearings which are self lubricating and provide a higher contact area than ball bearings reducing part wear. The igus material is available in filament form for 3D printing, offering up to 50x more abrasion resistance than standard 3D printing filaments. I150-PF is the easiest to print of these filaments as it does not require a heated build plate or closed chamber to print. Parts printed with I150-PF can operate between -30 and +65°C and the material has food contact approval according to EU 10/2011.
