I developed this static mixer design to streamline casting demos. Often times, a casting demo can get bogged down with portioning, mixing, and degassing, especially when you’re trying to have a group of students get hands-on time with the casting materials.
With this design, you load up degassed silicone, store the unit until needed, and then dispense mixed material out of the nozzle. If you’d like to build your own, you can find all of the source files on Thingiverse. This project was also picked up by Hack A Day.
