The Hemera does this by decreasing the gap between the drive wheels and the melting area. The best way for your filament to feed through the nozzle is through an extrusion system which is efficient and leaves little room for error. The fewer parts in an extruder, the better for the user in terms of putting it together, so this was one of the aims for the Hemera extruder, and it looks like they’ve achieved their goal brilliantly. It has various custom parts which not only give it a lovely, sleek look, but gives a convenient mounting slot and other features.
The Hemera was put together in a way that gives it a simple, yet high performing, compact design which works consistently with most FDM 3D printers. Compact & Seamless Systemĭue to the all-metal, stainless steel design, the size of the gears could be reduced, enabling the system to be more compact without sacrificing on performance. This results in a low-maintenance system and increase prevention of filament getting stuck in an oily extrusion system. It’s not necessary to lubricate the gearbox of the Hemera due to the hardened, stainless steel design. Similar to the Titan extruder, it has a self-cleaning characteristic as any loose remains slip off the extruder’s smoothed teeth. The individually CNC cut teeth on the drive gear, along with the rounded bottom profile supplies the solid grip, and resistance of filament remains jamming into the drive gears. This works so well because the user can adjust the filament tension through its secondary gear shaft, being on a movable, sprung idler. To gain a massive grip boost and filament force of up to 10kg, E3D used a hardened stainless steel dual-drive. You get very little slip, and plenty of grip because of the dual-drive gearsįeatures of the E3D Hemera Extruder Modern Dual-Drive Systemĭual drive systems (not to be confused with dual extrusion) are well known to supply a better performance than single drive systems.Small compact system which requires very little maintenance.Cooling fins provide highly effective cooling.Able to print at high speeds and maintain great quality.Very precise tolerances meaning flexible filaments can be printed easily.
#E3D HEMERA ALTERNATIVE UPGRADE#
There are many upgrade guides out there for specific 3D printers so it shouldn’t be too difficult to get it done for your printer. So if you have an extrusion-based 3D printer, you should be able to upgrade it to the E3D Hemera. This combination of features gives you plenty peace of mind over the quality of your prints, and pushes you to aim higher in your printing abilities, rather than just printing basic items. It gives your 3D printer exceptional pushing force, serious control over starts and stops, better filament grip which reduces the presence of grinding and slipping, and decreased blobbing and stringing. The E3D Hemera delivers exceedingly precise results by featuring a dual-drive, very short filament path and a reinforced stainless steel drive train. It’s also obtainable as a Bowden extruder system so it fits most people’s needs.
This allows 3D printer users to print flexible filaments with some of the industries best performance and accuracy, usually done at 50mm/s. The Hemera Extruder costs around ($130) from Amazon (or from the E3D website) for the Bowden & some extra for the Direct Drive version (around $150). What makes this extruder special is how it combines the market leading V6 hotend, with a newly developed filament drive mechanism which comes together to create an exceptionally responsive direct-drive extrusion system.
