E3D has launched the RapidChange Revo Roto, the “featherweight all-in-one extruder” that was announced during Formnext.

Weighing just 140 g, the Roto is designed to fully leverage the maximum volumetric flow rates of E3D’s Revo High Flow nozzles. It also features a 3D printed aluminum heat sink with “minimized wall thicknesses and skeletonized areas”, providing improved performance by way of thermal efficacy.

Removing three bolts will allow users to access the Roto’s internals while leaving the extruder’s body mounted in their 3D printer. Thanks to a “revamped” filament tensioning system, users can also change both nozzles and filament with one hand, E3D says.

The Roto arrives in standard, Bowden, and sensored versions, the latter of which features filament, fan speed, and heat sink monitoring, as well as a programmable “action button”. The action button functions similarly to those on the Prusa XL’s Nextruder, to which users can assign a shortcut to often-used features. In the Roto’s case, this could include loading or unloading filament, or preheating the print bed.

The RapidChange Revo Roto is currently available on E3D’s website, with standard and Bowden versions at around $145 (£115) and the sensored version at around $200 (£155).
