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.
Compact, Integrated System
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.
Filament Constraint Like No Other
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.
A Never-Before-Seen Heatsink
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.
Performance. Power. Push.
With 3:1 gear reduction, precision milled hobbed gearing and E3D engineering, we’ve developed Titan to push with awesome power, while also being incredibly light and compact.
The gear ratio means you’re able to use lighter motors as you’ll need less torque for the same filament pushing force - so direct drive systems have a lighter moving carriage, and bowden-style printers become powerful, reliable little beasts when combined with your E3D V6 hotEnd.
Titan fits perfectly into E3D’s modular ecosystem, Titan works for all configurations of bowden, direct extrusion, 1.75mm and 3mm. To switch filament diameters only the filament guide needs to be swapped out, and both 3mm and 1.75mm versions are supplied with every Titan. To use Titan as a bowden extruder you just insert a bowden adaptor into the body instead of a hotend. Bowden adaptors for 3mm or 1.75mm are available as a low cost optional extra.
Extruders with high gear ratios often struggle with snappy retracts and keeping up with Volcano for big, fast printing. Titan's balanced gearing ratio of 3:1 means that you can cope with fast extrusion situations like Volcaneo, and the lightweight gear-set gives snappy retractions.
Direct-drive extruders can have issues with ‘pulsing’ of flow, because the lower resolution of filament motion results in filament being extruded in pulses. This results in a slight wavy surface finish, and is particularly prevalent when printing at low layer heights. Using 3:1 gearing triples the resolution of the system and allows for smooth printing at the lowest of layer heights, using the smallest of nozzles.
A fully guided filament path from extruder to print means your filament is carefully guided every step of the way, ensuring a smooth journey to the meltzone. The guide constrains filament throughout the extruder, leaving no gaps and no opportunity for buckling of flexible filaments.
The CNC machined individually cut filament drive teeth allow grip of the slipperiest of Nylons.
A combination of grip and torque allows extrusion of even the most viscous materials like metal filled and carbon reinforced filaments.
1.75mm or 3mm filament: Titan is compatible with either diameter of 3D printing filament, and easily swaps between the two.
The extruder has ample force for even the toughest, gnarliest materials out there, ones that hat would cause lesser extruders to skip, grind or buckle.
