Last month, we reported the impending launch of E3D’s highly anticipated-yet-delayed Revo ObXidian nozzle. Now, a new, in-depth blog post from E3D details its features and properties – and announces the opening of preorders, with an estimated mid-November ship date.

According to E3D, the Revo ObXidian is “supported by three pillars of performance: thermal conductivity, non-stick and of course, wear resistance” and is “specifically designed for printing fiber-filled polymers.”

“Unlike other abrasion-resistant Nozzles,” E3D writes, “ObXidian’s copper alloy construction has a similar thermal performance to brass, making it a true drop-in replacement.”

This means users will not need to tweak temperature values. Instead, they’ll simply select the profiles they use for brass nozzles and start printing.

The nozzle’s non-stick coating helps plastic accumulations drop off before they become too unwieldy. By continuously depositing built-up filament, ObXidian greatly reduces the chances of print artifacts and blobs of discolored filament. The coating also results in a nozzle that is much easier to clean than standard brass nozzles.

For wear resistance, ObXidian leverages a hardened steel insert that is retained in the nozzle’s copper body. Its E3DLC coating, meanwhile – and in addition to its non-stick properties – is known for its extreme hardness. “Diamond Like Carbon (DLC) coatings,” E3D writes, “harness the strength of diamond bonds, the hardest material on Earth, in a lattice with graphite, to form a strong, wear-resistant coating.”

Pre-orders for 0.4 mm and 0.6 mm versions of the ObXidian nozzle are now open. The expected ship date is the week of November 14. According to E3D, 0.25 mm and 0.8 mm versions are coming soon. You can read the full version of E3D’s blog here.
