Both the drive gears and the hobbs are treated with Bastion, E3D's own ultra-hard coating, so they grip filament cleanly and hold their tolerances far longer than the stock parts they replace.\n\u003c\/p\u003e\n\u003cp\u003e\n\tThat matters most when you run abrasive material like carbon fiber or glass filled. Every meter of filament turns your extruder gears around 40 times, and each rotation slowly wears stock teeth down until extrusion starts to drift. Bastion gears are built to handle that and keep extruding accurately, print after print.\n\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\n\t\u003cimg style=\"display: block; width: 100%; max-width: 500px; height: auto; margin: 25px auto; background: transparent;\" src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0239\/9287\/files\/e3d_bastion_text.webp\" alt=\"E3D Bastion coated extruder gears and hobbs for Bambu Lab printers\" loading=\"lazy\"\u003e\n\u003c\/p\u003e\n\n\u003ch2 style=\"margin-top: 50px; margin-bottom: 25px; font-size: 1.8rem; text-align: center;\"\u003eThe Science Behind the Coating\u003c\/h2\u003e\n\u003cp style=\"margin-top: 25px; margin-bottom: 25px; text-align: center;\"\u003e\n\tBastion is a Diamond-Like Carbon (DLC) coating, applied to hardened steel with a Physical Vapour Deposition sputtering process.\n\u003c\/p\u003e\n\n\u003cp style=\"margin-top: 25px; margin-bottom: 16px;\"\u003e\n\tAgainst steel, dry, it measures a coefficient of friction around 0.1. In comparison, a common alternative like Titanium Nitride is roughly six times higher at every gear contact. DLC coatings also \"run in\", so friction drops a little further as the surface beds and the gears get smoother the more you print.\n\u003c\/p\u003e\n\u003cp style=\"margin: 0;\"\u003e\n\tThe coating is just 0.005 mm thick, around twenty times thinner than a human hair, so it adds no meaningful bulk and preserves the precision machining underneath.\n\u003c\/p\u003e\n\n\u003cdiv style=\"display: flex; flex-wrap: wrap; gap: 30px; align-items: center; margin-top: 50px;\"\u003e\n\t\u003cdiv style=\"flex: 1 1 300px;\"\u003e\n\t\t\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0239\/9287\/files\/bastion_gears_compared.webp\" alt=\"Four-way close-up of stock and Bastion coated hobbs, new and used, showing the stock teeth worn smooth while the Bastion teeth keep their sharp profile\" loading=\"lazy\" style=\"display: block; width: 100%; height: auto; border-radius: 8px; box-shadow: 0 2px 12px rgba(0,0,0,0.12);\"\u003e\n\t\u003c\/div\u003e\n\t\u003cdiv style=\"flex: 1 1 300px;\"\u003e\n\t\t\u003ch2 style=\"margin: 0 0 16px; font-size: 1.8rem;\"\u003eProven to Outlast Stock Gears\u003c\/h2\u003e\n\t\t\u003cp style=\"margin: 0 0 16px;\"\u003e\n\t\t\tRan completely dry, Bastion gears outlasted lubricated uncoated gears by five times in tooth contact cycles.
