You still do need a heatsink for the coldside of the hotend, and you get the choice of using Revo6, which, size-wise, is completely compatible with the old v6 form factor, and that’s what I used to upgrade one of my Prusa MK3s. The essence of Revo is the new nozzlebreak, which combines what used to be a separate nozzle and heartbreak into a single part, as well as the new heater core, which used to be a separate heater block, heater cartridge, and thermistor. It’s not called v7, and I think that makes a lot of sense, but that’s something I want to get to later. Let’s get started with the disclosure: E3D sent me all these parts free of charge to try out, I do not have to send them back when I’m done, no money changed hands and E3D does not get any influence in this review, but the links in the description where you can buy the Revos are affiliate links. After using the Revo for a couple of weeks and putting it through one of the most extensive testing sets I’ve ever done on a product, I’ve got some thoughts, graphs, and numbers I want to share with you. You get the new quick-swap nozzlebreaks, a new self-regulating heater, an optional smaller form factor, significantly better performance and a new patents package that makes sure nobody will ever be making nozzles or heaters without E3D’s approval. It’s time to take an in-depth look at E3D’s newest hotend ecosystem – the RapidChange Revo. Let’s get it tested and find out if it’s worth it! BIQU does say ‘upgradable to 500☌’ on its website, which will require swapping to a all-metal heat-break – I can’t find this listed on the website – as well as a different sensor.E3D’s new RapidChange Revo system breaks with existing standards – and it comes with news highlights and drawbacks. The top end of lined extruders is limited by the PTFE emitting undesirable vapours – BIQU is using special Capricorn PTFE, and most PTFE lining is only rated to 245 or 250☌). H2 has a ‘PTFE-lined’ hot-end and BIQU rates it to 260☌ max. That said, there have been quality issues with some batches of Hemeras (or is Hemera the plural? a question for E3D?) which resulted in a lengthy removal from sale for a re-design (I don’t think Covid-19 helped either), but it is said to be back on the shelves, though out-of-stock at the time of typing. I did wonder if the re-design would include a small motor ‘inspired by’ H2….Īside from motor dimensions, one other difference between E3D and BIQU products is that Hermera is ‘all-metal’ and prints up to 285☌ (up-gradable to 500☌ with a different temperature sensor) and so is already nylon-capable. Hemera has had rave reviews for its print quality: printing even very flexible filaments at speed with precision. How H2 (or ‘H 2‘? a question for Bigtree) prints has not yet been tested extensively, but reviews of pre-production BX 3d printers were favourable. I wonder if the E3D team are kicking themselves for not moving to a smaller motor? Its design tightly-constrains the filament path (max unconstrained length 0.25mm) to allow a wide range of filaments, even very flexible filaments, to be printed.Īmongst innovations, they shrunk dimensions by burying parts of the gearbox inside the end of the motor and the heatsink, and creating a curvy heatsink that pushes cooing air flow away from the printer tip – much of which have been picked up by BIQU in H2. The folk at E3D (which is UK-based and the home of the much-trusted V6 hot end) thought well outside the box when they created Hermera (code-named Hermese during development), which nominally weighs 388g.
