The E3D Hemera is a dual-drive extrusion system complete with a fully hardened stainless steel drive train and optimized heatsink design. Created by E3D to ensure high-quality components and durability. The E3D Hemera offers extraordinary filament control and allows the 3D printer user to take flexible printing to the next level, thanks to its super constrained filament path. This is a bowden version for mounting onto a frame, where the filament is pushed through a bowden tube.
For E3D Hemera, we opted for a hardened stainless steel dual-drive arrangement which provides a huge boost in grip over single drive systems, in fact, we’re able to push filament with up to 10kg of force. The secondary gear shaft is on a moveable, sprung idler which allows the user to adjust filament tension.
Hemera is a system of components designed to work seamlessly together as a single compact product. It has a custom motor which is based on a NEMA17, along with our own faceplate designs which has allowed us to add our own features for user convenience, such as mounting slots as well as produce a very compact system.
Hemera constrains filament like no other extrusion system, fact. You won’t experience the full extent of its unrivalled filament constraint until you print ultra-flexible materials. This exceptional filament constraint also has a significant impact on printing rigid, and semi-rigid materials such as PLA or Nylon.
Hemera features convenient T-Slots for easy mounting to your printer, plus space for other accessories, part cooling fans and bed levelling probes to name a couple.
Hemera’ heatsink design ensures 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.
All interaction with Hemera is from the top. To set filament tension the user simply twists a thumbscrew and a cam slider mechanism with a captive nut compresses a spring and loads the idler. Filament tension is increased by rotating clockwise and decreased by rotating counterclockwise. Simple. Should you need to disassemble Hemera for maintenance, the internal mechanisms are easily accessible by removing the fan, and undoing the two faceplate screws. Full access is available to clean and replace parts even while filament is loaded. When you pop off the faceplate the filament, idler and spring all come along too, as one neat assembly.
