Revo Hemera is a compact, powerful extrusion system with the convenience of E3D’s RapidChange Revo ecosystem. With dual drive gears and hardened steel hobbs to grip filament from both sides, Revo Hemera gives your 3D printer exceptional pushing force. A tightly constrained filament path means material can’t flex and bend on its way to the melt zone, making it a top choice for challenging 3D printing filaments, like flexibles.

Compatible with Revo Nozzles so you can change nozzles at room temperature using just your fingers

Custom motor end-caps provide convenient T-slots for flat mounting, leaving plenty of room for other accessories, like bed leveling probes or part cooling fans

Compatible with many popular 3D printers, including the Creality CR series and Ender series, Prusa, Anet, Biqu, Monoprice, and many more. Check out our 3D printer upgrade guides

Everything you need is get started is included in the box – just mount it to your 3D printer and start 3D printing

Ready for Revo.

Change nozzles at room temperature using just your fingers. No complex tools, no hot tightening. Revo Nozzles are factory sealed nozzle and heatbreak in one, so they’re easy to fit and can’t leak material when in use.

New hotness.

A Revo HeaterCore heats up in seconds. It’s much safer too – unlike other solutions on the market, a positive temperature coefficient (PTC) means the Revo HeaterCore can not melt at extreme temperatures: power reduces as it gets hotter, so hazards are reduced in the event of a thermal runaway.

Tight filament path.

Hemera is a combined extruder and HotEnd, so it has fewer transitions than most extrusion systems available. A tight filament path gives it excellent performance with hard-to-print materials, like flexibles. Even with the softest flexibles, you can print without the underextrusion or filament binding you would get with a typical setup.

Resistant to wear.

Hemera’s stainless steel hobb teeth are resistant to wear, so with the right combination of components, your Hemera can effortlessly 3D print advanced abrasive and composite materials, like carbon fiber-filled filaments, for serious industrial applications.

(Disclaimer: abrasion-resistant Revo Nozzle required – ETA 2022)

Optimized airflow.

Hemera has a uniquely designed lightweight aluminum heatsink for highly effective cooling. Air is circulated through the fins and then up and away from the 3D print, preventing any unintentional warping of the printed part.

No loss of torque.

Hemera’s 3.32:1 dual drive gears produce pushing force of up to 120N on your filament from both sides, for accurate, controlled extrusion with no loss of torque. Sharp, individually machined hobb teeth ensure excellent filament grip strength, and round-bottomed profiles help to reduce any build-up of filament debris, for high-quality, consistent extrusion from first to final layer.

E3D quality.

Each Hemera drivetrain includes shielded bearings and high-quality igus® bushings for optimal wear resistance. Lubrication is precisely applied to each drivetrain by robots during assembly, and drivetrains are thoroughly analyzed using an accelerated wear test to ensure your Hemera will have many years of 3D printing life.

Mounting options.

Hemera’s custom motor end-caps provide convenient T-slots for flat mounting on many popular 3D printers, leaving plenty of room left for other accessories, like bed levelling probes, or extra part cooling fans. 

Flexible to any setup.

Hemera plays nice with Bowden and direct drive setups. Just add a Bowden adaptor (sold separately) and your Hemera becomes a powerful Bowden filament drive.
