Change your 3D printer nozzles in less than 60 seconds without tools or hot pressing, just use your fingers! If you can unscrew a tube of toothpaste, you can use a Revo nozzle. Just screw one in any cold place from Revo and you're ready to print in 3D. No frustrations. Each Revo nozzle is a pre-assembled nozzle and HeatBreak in one unit, so there is no dangerous hot clamping and no chance of improper assembly. Say goodbye to frustrating HotEnd leaks and enjoy reliable 3D printing! An expanding range. We are ready to make RapidChange nozzles in any size. Currently, we have brass nozzles in 0.15mm, 0.25mm, 0.4mm, 0.6mm and 0.8mm, with many more compatible nozzles to follow later. The wear-resistant and high-throughput variants are already on our roadmap and will continue over time.
