The Form 4L Resin Mixer improves material performance by keeping resin homogenous in the tank during the printing process. A Resin Mixer is required anytime you are printing. Resin Mixers typically last for the lifetime of your printer.
For convenience, we recommend having one Resin Mixer for each Resin Tank.
