but why didn’t you just make Revo Nozzle X? There have been countless occasions when we couldn’t get good parts or sometimes any parts at all. Sprinkle in ludicrous lead times and you have a recipe for major delays. If one process changes even subtly, work must be done to make sure all the others are still fine. There are a lot of complex processes involved in making a product like ObXidian. Here’s an extract from our recent ObXidian Update blog, if you’re interested in knowing more, it’s well worth a read. Introduction to PECVD.Įxcept for this one! This is the Revo 'ObxidiCorn' designed by Thorsten Hartmann If you're interested, this video gives a fantastic explanation as to how that technology works. If you read our recent blog about some of the challenges we've been facing while developing ObXidian, you will have seen that E3DLC is applied by plasma-enhanced chemical vapour deposition (or PECVD). There are a number of different ways that thin-film coatings such as DLC can be applied to components. The E3DLC coating has been custom designed at the atomic level to offer an unparalleled combination of wear resistance with anti-sticking properties. DLC coatings are not all the same, depending on composition and manufacturing process. The DLC coating also offers many other intrinsic benefits such as low friction, chemical resistance and thermal stability. What is E3DLC? - We hear you askĭiamond Like Carbon (DLC) coatings harness the strength of diamond bonds, the hardest material on Earth, in a lattice with graphite, to form a strong, wear-resistant coating. We advise against using brass brushes or even paper towels to clean Nozzle X, as these quickly wear away its delicate non-stick coating. Nozzle X also has a non-stick coating, but it’s fair to say it doesn't really repel polymers. A true drop-in replacement for your brass nozzles.Īn ObXidian Revo Nozzle after a print with the same G-code Nozzle X vs ObXidian Simply select the profile you would use for your brass nozzles and hit print. ObXidian’s copper-alloy construction means you no longer need to spend time fiddling with temperature values to account for the weaker thermal performance of other abrasion-resistant nozzle offerings. So, when you offset your HotEnd temperature, what you're actually doing is artificially inflating the temperature elsewhere in the system to try and achieve the same results in the plastic. When you change the nozzle material, which is between the heater and the plastic (not the heater and the sensor) the plastic won't necessarily see the same temperature anymore, due to the new material's weaker ability to transmit the heat from the heater block through to the plastic. If you’re wondering why you need to raise your temperatures, it’s because the temperature that the printer is actually trying to maintain is the temperature at the sensor and not what is being reached by the plastic flowing through the HotEnd. When customers install hardened nozzles and forget to change their slicer settings, it leads to print quality issues, clogging and precious time lost for everyone involved. It’s a nightmare for OEMs, who invest hours perfecting print profiles in their slicers. Hardened steel Nozzles like Nozzle X can require you to bump up your HotEnd temperature by around 10 degrees to achieve the same results as when printing with standard brass. In this blog we’ll break down what each of these mean and explain why they matter. Thermal conductivity, non-stick and of course, wear resistance. ObXidian Nozzles are supported by three pillars of performance.
