E3D Revo Roto Extruder

 Roto is the extruder that Revo deserves. It carefully balances weight (140g) and force (70N+) to provide the lightest, most power-dense 3D printing extruder on the market.

Lightweight yet full of force

The roto gearbox consists of a planetary initial stage followed by a spur secondary stage with a dual hobb third stage.  To put it concisely, this results in enough extrusion force to fully utilise our Revo High Flow nozzles' maximum volumetric flow rates while providing a favourable motor stall (rather than filament grind) failure mode.

Maintenance minded

Ease of use was a major consideration in the design of Roto. To access the hobbs all you need to do is remove three bolts to remove the heatsink and filament path whilst leaving the body of your extruder mounted in situ.

We have also revamped the filament tensioning system, providing a simple bi-stable mechanism that either provides the optimal tension or completely releases the tension to help with filament loading and cold pulls. This means you can change the nozzle and release the filament with one hand.

Cool Design

Roto features a first of its kind 3D printed metal heatsink. SLM 3D printing gave us unparalleled design freedom, which means beyond the obvious cool factor of using this technology, the design has been highly optimised. The heatsink prevents heat creep by reducing heat build-up via conduction and directs air through the air-break to disrupt the radiating heat from the HotSide, resulting in the most thermally effective heatsink we have ever produced.

Standard… or smart

Roto's evolution doesn't stop at the base performance characteristics you're used to. Upgrade to the sensored bundle to add filament monitoring, an action button, fan speed monitoring and heatsink temperature monitoring to your arsenal. With all these improvements, you can implement peace of mind within your workflow with remote monitoring and quick, simple maintenance for the most hands-off 3D printing experience ever.
