Unlike simple traction systems, in which only one of the drive wheels is in charge of pulling the filament, in dual-drive systems both hobbs are geared with each other. With Hemera, E3D steps forward and introduces its first “dual-drive” extruder, the technology that made Bondtech extruders the undisputed leader. Source: E3D E3D's first dual-drive extruder By replacing the nozzle and the standard heater block with nickel-plated copper ones and replacing the thermistor with a PT100 thermocouple, it can reach temperatures of up to 500✬.
As standard it can reach a maximum temperature of 285 ✬. It has dimensions of just 77 x 44 x 83 mm and a weight of 388 g. Although it is an extruder developed to operate in direct mode, it also supports mounting in bowden systems. Unlike the other E3D extruders, the Hemera drive train is made entirely of hardened steel and the distance between the pull point and the melting point is minimal. It is a dual-drive type extruder for 1.75 mm filament that incorporates the famous hot-end V6. Video 1: E3D Hemera promotional video.

E3D Hemera is one of the most advanced direct extruders on the market. It is mainly recognized for its famous hot-end E3D-V6, and for Titan and Titan Aero extrusion systems. E3D is the most important international company in the development of high-quality hot-ends and one of the main companies, together with Bondtech, in the development of extruders.
