E3D-Online has designed a new dual driven extruder, known as the E3D Hemera. It was previously known as the E3D Hermes

Statement from E3D

“You’re probably wondering why at the last minute everything that you were expecting to be called ‘Hermes’ is now called ‘Hemera’.

Unfortunately, less than 24 hours before launch, we received a legal challenge from a company much larger than us, and with significantly more legal resources. They objected to us naming our product after a Greek god from the Mycenaean era, as they feel that name belongs to them. Unfortunately, we don’t have the time or resources to resolve this through a long legal process and we just want to get on with making incredible extrusion systems. Therefore we’ve had to undergo a rapid unscheduled rebranding, and have settled on Hemera, a somewhat less fashionable Greek god, yet still in keeping with our other mythological names, and our first female one too. Please do excuse us if some of the content is slightly less polished than usual, it’s been a long hard night. If you see any instances of the old name hanging around please do let us know too.

Thanks in advance for your understanding.”

Read on E3D Hemera…

The news was announced at the TCT show 2019 in Birmingham. By getting the workings of a dual drive extruder, they have developed their version with some added benefits!

Therefore, by combining a hotend and extruder, they have created an all in one system which does both!

Using hardened metal dual gears, each groove in the gears is custom milled rather than being tapped therefore allowing a better grip on filament. Due to the material type and in addition to using Igus bearings, lubrication is not needed so as a result, they are low maintenance!

What else is new with the E3D Hemera?

In addition to the above, the E3D Hemera has an aluminium body which is designed to enhance the airflow. Therefore, you can use lower-rated fans. Above all, the airflow is redirected to blow upwards rather than on the print area.

It uses a custom made Nema 17 motor. They have replaced the end caps with customised parts using die casts and machining technologies. Additionally, to help in the mounting of the E3D Hemera, T-nut slots have been inserted into the caps. As a result, this assists in mounting the extruder as well as other technologies, such as a BLTouch.

Other info…

The E3D Hemera AKA Hermes is designed so that any tinkering is done at the top rather than fiddling down the bottom. The size of this is smaller than their Titan Aero Extruders. Also, they are following what Prusa Research do when it comes to quality checks. E3D will mark each one with QC so that it can be tracked down to its origin!

To get rid of the gap between the extruder and nozzle, the filament is pushed directly into the heartbreak. As a result, this allows for ease of use when using flexible filaments.
