Roto Extruder Prusa MK3 Edition

Please note: This Extruder kit is not compatible with the Prusa MK3.5.

Please note, this kit is designed specifically for use with a Prusa MK3. If you're planning to install Roto on a different 3D printer then please use this link.

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. Why not add the MK3 Roto Filament sensor to your printer to implement peace of mind within your workflow with remote monitoring and quick, simple maintenance for the most hands-off 3D printing experience ever.

Pair with your perfect Hotside

Pair your Roto Extruder with one of our carefully curated Hotside packs to ensure your printing needs are met, straight out of the box. All Hotside packs come with your heating and sensing elements plus a variety of nozzles for you to start quick swapping with. Select from the following options: 

Starter - Ideal for users printing at standard speeds with PLA, PETG and ASA 

High Flow - Perfect if you're looking to push your Prusa printer's print speed capabilities to the limit 

High Flow X - All the benefits of the High Flow pack with the bonus of abrasive resistance for printing with fibre filled materials 

Please note:

• This kit does not include the Roto Filament Sensor as it is only compatible with the MK3S and MK3S+. You can purchase it separately here.
  
• We have not tested MMU1, 2 or 3 units with roto and are therefore unable to provide support for these configurations.
• This kit is not compatible with the Prusa MK3.5
