E3D Hemera Direct
A Next Generation HotEnd and Extrusion System
Introducing E3D Hemera, a dual-drive extrusion system complete with a fully hardened stainless steel drive train and optimized heatsink design. E3D Hemera offers extraordinary filament control and allows the end user to take flexible printing to the next level, thanks to its super constrained filament path.
E3D Hemera features a dual-drive, hardened stainless steel drive train, which provides a huge boost in grip compared to single drive systems; we are able to drive filament with 10kg of force.
Individually CNC cutting each hobb tooth allows for a round-bottomed root, with a tooth that curves upwards to a robust, sharp tip. The round bottom of the profile strongly resists filament debris wedging into the drive gear and in almost all cases it’s self-cleaning as any debris simply falls off the teeth.
Compact, Integrated System
Hemera is a system of components designed to work seamlessly together as a single product, creating a compact extrusion system with a reduced part-count.
Hemera has a custom motor, based on a NEMA 17 frame, with our own bespoke faceplate which allows the motor itself to be part of the extruder housing. We’ve also added convenient versatile mounting T-Slots on both sides, which makes it simple to mount to printers, and provides useful mounting points for accessories such as part-cooling and bed-levelling systems.
Unparalleled Flexible Printing
Hemera constrains your filament like no other extrusion system. You won’t truly ‘get’ the impact of the optimized constraint that Hemera provides until you’ve printed flexibles with it. But trust us - the performance is second to none and also has a significant impact on printing normal materials such as PLA or PETG.
This new heatsink design was a result of extensive testing to ensure that airflow is diverted up and away from both the HotEnd and the heated bed, reducing the risk of warping and uneven stresses forming in the printed part.
E3d Nozzles and Blocks fit on the Hemera! You are not just limited to the Aluminum Block and Brass Nozzle.

1/8/2019 at the request of E3D we are temporarily holding off sales of the Hemera hotend till the problem is rectified. This should only be for a few days. In the meanwhile. You can sign up to be notified once they are back in stock and as soon as this issue is corrected we will put them back up.
1/9/2020 E3D has released a QC check and we at PRINTEDSOLID will QC every Hemera hotend before shipping there is no delay on shipments QC checks are underway and ongoing for inventory.

Printed Solid has the Hemera in stock which is a miracle. The Hemera itself is a great upgrade to the Ender 3 and the setup was very easy. Best recommended upgrade to take the printer to the next level
Easy to install drop-in replacement for your hotend!
This was basically a drop-in replacement for direct-drive assemblies. I mounted it to a Printermods MDD plate on an Ender 5. Had to get this after my janky E3D V6 + HeroMe mount proved to be too unreliable. This, on the other hand, is perfect! No clogs, no problems! I paired it with a Noctua fan to make it extra quiet as well.
Hemera on Ender 3 Pro
Installation was moderately advanced but I expected that given the research I did prior to purchasing. Bought primarily to print flexible filaments but does an excellent job at standard PLA as well. I found that I needed to modify my feed and spool holder on the Ender 3 Pro to prevent flexible filaments from binding but after some tweaking and further modifications to my printer everything is working great on what I've tested so far!
Great upgrade, the process could use some work
Overall, I really find this a worthwhile upgrade. The reduced retractions have improved my print times on long prints and there's a noticeable improvement in print quality. I know a lot of people talk about this as an upgrade only for people who print flexibles, but I think that's not entirely true. I've never printed flexibles and I don't have any plans to. I do however print a fair bit in white PETG. If you've never printed with white PETG, let me tell you how badly that stuff strings regardless of retraction distance. The titanium dioxide used to get that bright white color just makes it string like crazy. With the Hemera, the problem is completely gone. For me, this loses a star because the process of integrating it is pretty sloppy IMO. There are plenty of print at home mounts for this, but the one for my CR10S Pro left something to be desired. If you're going to put out a product that will require adapters for every printer it goes on, you've gotta nail that. I wound up having to tweak the files myself to make them work.
Works fantastically and was easier to make a custom mount for than any other Hotend I've used before!
