E3D High Flow ObXidian® A1 HotEnd

Boost your 3D printing performance with the E3D High Flow ObXidian® A1 HotEnd — a high-efficiency, durable upgrade designed to deliver superior extrusion flow, longer nozzle life, and consistent printing quality even with challenging or abrasive filament types. Perfect for users who want fast, reliable 3D printing without frequent nozzle changes.

Why Choose the ObXidian® A1 HotEnd?

• Enhanced flow rates: The optimized internal melt zone improves filament heating and flow, enabling significantly higher extrusion speeds and throughput compared to conventional hardened hotends.
• Durable wear-resistant construction: Built with hardened ObXidian® A1 nozzle material and a protective coating — providing excellent abrasion resistance for extended nozzle lifespan even when using abrasive filaments like carbon-fiber, glass-fiber, metal-filled, or glow-in-the-dark.
• Smoother extrusion & reduced maintenance: The low-adhesion nozzle finish minimizes plastic build-up, reducing clogging, stringing, and the risk of head crashes during long or high-speed prints.
• High-temperature capable: Designed to handle elevated printing temperatures — making it suitable for a wide variety of filaments when paired with compatible hardware and calibration.
• Versatile upgrade path: The ObXidian® A1 is an excellent choice whether you’re replacing a worn nozzle or upgrading your setup for better performance out of the box.

Technical Specifications

• Filament diameter: 1.75 mm
• Nozzle sizes: 0.40 mm or 0.60 mm (depending on variant)
• Nozzle material: Hardened ObXidian® A1 with wear-resistant coating
• Internal design: Optimized melt zone for improved thermal transfer and flow consistency

Best For

• Everyday printing of PLA, PETG, ABS and similar materials where users want increased reliability and throughput.
• Prints involving abrasive or composite filaments (carbon-fiber, glass-fiber, metal-filled, glow-in-the-dark) — where durability and wear resistance matter.
• Long print runs where nozzle longevity and minimal maintenance are priorities.
• Upgrading from a stock or worn nozzle to achieve smoother extrusion, more consistent flow, and reduced downtime.

Whether you’re printing hobby models, functional prototypes, or abrasive composites — the E3D High Flow ObXidian® A1 HotEnd delivers better flow, improved durability, and reliable extrusion. Upgrade today for a smoother, faster, and longer-lasting 3D printing experience.
