What is ObXidian made from?
ObXidian is made up of many materials and processes. Starting at the Nozzle tip, we’ve got a specialized hardened steel, with the rest of the nozzle portion being made up of Copper. Then we have a steel tube, and finally, a copper threaded portion. For the literal icing on the cake, the assembly is then coated with E3DLC™.
What HotEnds are Revo Nozzles compatible with?
Any of our Revo range are compatible with ObXidian.
Will there be 2.85mm Revo nozzles?
Simple answer, not as standard. If you’re a printer manufacturer using 3mm, please reach out!
Is it possible to wear out an ObXidian Nozzle?
Our testing has shown that under normal printing conditions, even when printing abrasive materials, ObXidian Nozzles can last almost indefinitely. That’s not to say they are indestructible though; we have successfully worn ObXidian Nozzles in some extreme testing.
UV-reactive/ “glow in the dark” filaments include an additive called Strontium Aluminate. Strontium Aluminate is very hard. So hard, in fact, that when printed at very high movement speeds, the deposited layers begin to work like sandpaper. We’ve found these conditions to be capable of removing the E3DLC coating and therefore can have a permanent impact on the wear resistance of the nozzle.
We’re not saying you need to totally avoid using glow-in-the-dark. We’ve successfully run multiple kilograms of glow-in-the-dark filament through an ObXidian Nozzle without seeing any impact to the nozzle's performance. Turns out it’s a lot more complicated than wear being proportional to speed, but we’ve been using the Prusa MK3S+ with the 0.2 Quality settings with good success for most model geometries. If in doubt, print slow.
Why is there a brown slip of paper packaged in with my ObXidian Nozzle?
The brown slip of paper is there to offer corrosion protection for metal parts during shipping and storage. It is VCI paper which stands for ‘vapourised corrosion inhibitor’. This paper is chemically coated and produces gas progressively over time. These VCI molecules form a thin, invisible layer on the Nozzle which prevents oxygen from touching it. Thus preventing corrosion.
It’s potentially a little overkill, but it’s the details that matter! Your ObXidian should arrive in the same pristine condition that it was in when it left E3D.
