E3D High Flow ObXiDian 500 X1C HotEnd

Go with the Flow

The ObXiDian® 500 X1C HotEnd features E3D’s innovative 4-channel internal nozzle design, dramatically improving heat transfer through the filament. This enables smoother, more consistent extrusion and up to 60% higher volumetric flow, allowing you to print faster without compromising accuracy or detail.

Engineered for Longevity

Built using E3D’s latest ObXiDian® 500 coating technology, the HotEnd is over five times more wear-resistant than the original ObXidian®. Its hardened surface easily withstands abrasive filaments like carbon-fiber, glass-filled, and glow-in-the-dark materials — ensuring long-lasting performance and consistent print quality over time.

Print Any Filament

From everyday PLA and PETG to engineering-grade composites, this HotEnd handles them all with ease. Its ultra-durable construction prevents nozzle erosion and clogging, allowing you to explore new materials and print at higher speeds without compromising reliability.

Cleaner, More Reliable Prints

Thanks to its low-friction, non-stick surface, molten plastic doesn’t stick to the nozzle tip. This prevents build-up and improves print finish while reducing the risk of print crashes and imperfections — keeping your X1C performing at its best, print after print.

Effortless Installation

The ObXiDian® 500 X1C HotEnd is designed as a direct drop-in replacement. Installation takes seconds — simply unclip the existing HotEnd and attach the new one. No adjustments, tools, or firmware updates are required, making this one of the most seamless upgrades for your Bambu Lab X1C.

An Official Bambu Lab Collaboration

This HotEnd is the result of an official partnership between E3D and Bambu Lab, ensuring full compatibility and professional-grade reliability. For every unit sold, E3D pays a royalty to Bambu Lab, which donates 50% of that amount to the Sanjay Mortimer Foundation — a charity supporting neurodiverse young engineers passionate about creativity and innovation.
