E3D Bastion Coated Gears for Bambu Lab X1 & P1 3D Printers
$62.99
E3D Bastion Coated Gears are a hardened steel extruder upgrade for Bambu Lab X1 and P1 series 3D printers. Both the gears and hobbs are treated with Bastion, an ultra-hard, low-friction Diamond-Like Carbon (DLC) layer that grips filament and minimizes wear from abrasive materials.
E3D Bastion Coated Gears for Bambu Lab (X1 / P1)
The Bastion Coated Gears are a precision-machined, hardened steel extruder upgrade for the Bambu Lab X1C, X1E, P1P, or P1S. 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.
This makes sense when you run abrasive material like carbon fiber or glass filled. Every meter of filament turns the extruder gears around 40 times, and each rotation slowly wears down the stock teeth until extrusion drifts. Bastion gears are built to handle that and keep extruding accurately, print after print.
Why Choose Bastion
The Science Behind the Coating
Bastion is a Diamond-Like Carbon (DLC) coating, applied to hardened steel with a Physical Vapour Deposition sputtering process.
Against 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.
The 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.
Proven to Outlast Stock Gears
Ran completely dry, Bastion gears outlasted lubricated uncoated gears by five times in tooth contact cycles. With a little lubrication, they passed two million contact cycles, at which point the test was stopped because they simply would not fail.
The coating also raises load-carrying capacity by 10 to 15 percent. It reduces stress on the gear flanks, so they handle heavier loads for longer without showing fatigue.
Stock and Bastion hobbs, new and after extended use. The used pair ran the equivalent of 12 months of printing: at least 20 kg of fibre-filled material, 10 kg of glow-in-the-dark, and the usual standard test filaments. The stock teeth round off, while the Bastion teeth keep their edge.
Technical Parameters
Frequently Asked Questions
- Will the gears wear out?
-
Yes, given enough time the gears may exhibit wear, but will do so considerably slower than the stock option because their unique coating gives them a significantly higher hardness level. Wear resistance is difficult to quantify due to the numerous variables involved, including base polymer, additive, brand, temperature, and print speed.
- Do you need to lubricate the gears?
-
Lubricating the gears will make them last even longer so we recommend that you do this every couple of months, but their self-lubricating coating makes them last longer than the stock option even when run dry.
- Will the gears improve my print quality?
-
The combination of precision-machined gears and a coating that stops them from wearing gives users consistent extrusion that stays consistent for longer than the stock option. This helps maintain quality and reduces the chance of unwanted print artifacts and layer lines.
