iMakr's VerdictTribology 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. Iguldur I170-PF has higher wear resistance than I180-PF but a slightly smaller operating temperature range than J260-PF.
