filament check valve / return brake for MMU application
cults3d
Visit my website at https://www.printschnitzel.at/. On February 9th, 2019, version 2.0 was added. This is a one-way valve for filament that can be used in MMU applications. Use a ball with a diameter of 4mm; you can find one inside every 608 bearing. Although meant to be a concept, it works surprisingly well. The screw holding the ball in place could be replaced by a closed channel for the ball, and placing the ball during printing would make it airtight. Use higher infill density than I do to keep the ball securely in place. Watch the video at https://youtu.be/xhIuAQ11Dec. Do you have a better name for this device? If so, please leave a comment; thanks. My first language is not English, and I'm unsure if "check valve" accurately describes it.
