Its new hot-end is branded Revo, and is an ‘all-metal’ design, allowing printing at up to 300°C. “Revo enables you to rapidly change nozzles, making it easier to use the right tool for each job or material,” according to the company. “Simply unscrew the nozzle with your fingers at room temperature, and then screw in a new one. That’s it – no tools, no hot-tightening, no fuss.” Each nozzle variant will be colour-coded, allowing extrusion diameter to be identified at a distance. Rather than a heater cartridge, thermistor and heat transfer block to take heat to the nozzle, as the V6 has Revo has the heating element wrapped around the nozzle as part of a cylindrical block with an integrated thermistor – with significantly less thermal mass that the V6 leading to faster heat-up. “We understand the fundamental physics of extrusion systems for FFF 3D printing better than anyone else, and we’re proud to have poured everything we know into this new ecosystem,” said E3D. For backward-compatibility, Revo Six will be a drop-in replacement for V6 hot ends, there will be a version to suit the company’s Hemera extruder, and the standard Revo will be the lighter and smaller Micro. Printing at up to 300°C. 0.25, 0.4, 0.6 and 0.8mm brass nozzles. The E3D website is here and there is a brief Revo video.
