Draining the resin cartridge (Form Studio 1)

Formlabs SLA printers dispense resin from resin cartridges into resin tanks, which hold the liquid resin used during a print. The Drain cartridge function empties remaining resin from the inserted cartridge so it can be replaced and disposed of. This can be useful if you want to finish a resin cartridge but do not want to be interrupted during a print.

To drain a resin cartridge: 

1. If you have not done so already, insert the resin cartridge you want to drain into the printer.
2. Open the printer cover.
3. Insert and latch an empty resin tank or a used resin tank holding the same resin as the cartridge.
4. Close the printer cover.
5. On the printer touchscreen, tap Settings > Tools > Drain cartridge. The Drain cartridge screen appears.
6. Tap Start to begin draining the resin from the cartridge into the tank.
   • If you have not inserted the required consumables or they are mismatched, the printer prompts you to correct the issue.
   • If the resin tank is too full to hold the remaining resin in the cartridge without overflowing, the printer warns you. Tap Ignore to drain the cartridge anyway or Abort to exit the tool.
7. Wait for the resin cartridge to drain into the tank. This may take several minutes depending on the amount of resin in the cartridge.
8. When the cartridge is fully drained, the printer displays the message Cartridge drained successfully. Tap Close to continue using the printer.
