Light yet powerful. The Roto gearbox consists of a first planetary stage, followed by a second spur gear stage and a third stage with two rolling cutters. In short, this results in sufficient extrusion force to fully utilize the maximum volumetric flow rates of our Revo High Flow nozzles while ensuring a favorable failure mode for motor shutdown (instead of filament grinding).

Maintenance-conscious. Special emphasis was placed on user-friendliness during the development of Roto. To access the rolling cutters, only three screws need to be removed to take off the heatsink and filament path, while the extruder housing remains mounted in place. We have also revamped the filament tension system and developed a simple, bi-stable mechanism that either provides optimal tension or completely releases it to facilitate filament loading and cold pulls. This means you can change the nozzle and release the filament with one hand.

Cool design. Roto features the first 3D-printed metal heatsink of its kind. SLM 3D printing allowed us unprecedented design freedom, meaning the design has been highly optimized beyond the obvious coolness factor of this technology. The heatsink prevents creeping heat by reducing heat buildup through conduction and directing air through the air break to interrupt the heat radiation from the hot side, resulting in the thermally most efficient heatsink we have ever produced.

Standard or smart. The development of Roto does not stop at the basic performance features you are used to. The sensor bundle expands your arsenal with filament monitoring, an action button, and monitoring of fan speed and heatsink temperature. With all these enhancements, you can...
