Form 4 Mixer

The Form 4 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 Form 4 Resin Tank.

Form 4 Resin Tank

Low Force Display™ (LFD) 3D printing uses a flexible yet strong dual-layer film tank for consistent, high-quality prints. Every resin tank includes a reusable lid, making it easy to stack tanks and store resin outside of the machine. With a separate tank for each individual resin color or type, switching materials is as easy as sliding in a new tank.
Resin Tanks are built to last and deliver consistent performance for at least 75,000 layers of printing — approximately 340 prints using clear aligner models (22 mm tall), any resin, and 100µm layer height
