Formlabs Form 3 Cartridge Spring Fingers Kit
The cartridge floor contains a set of spring fingers that read the cartridge ID chip and a motorized dispense arm attached to a spring.
When the printer, using the LevelSense measurements, determines that the resin tank needs to be refilled, it activates the dispense arm.
The dispense arm, driven by a motor underneath the cartridge floor, squeezes the bite valve on the bottom of the resin cartridge. Once the tank has been refilled, the spring attached to the dispense arm pulls it out of the way so that no resin is dispensed inadvertently.
