The Formlabs Resin Pumping System lets you print more efficiently than with traditional resin cartridges. The system uses a five liter resin container and a motorized pump to dispense resin into the resin tank, leading to fewer print disruptions and reducing the consumption of single-use plastic.

1. Resin pump: A motorized pump draws resin from the resin container through the transfer tube to dispense resin into the resin tank.
2. Transfer tube: A silicone tube used to transfer resin from the resin container to the resin pump.
3. Transfer cap: A cap with an output barb used to attach the transfer tube to the resin container.
4. Resin card: An RFID card included with the resin container that is programmed with the resin container’s resin type. The RFID chip comes attached to an instruction card in the box.
5. 5 L Resin Container: A five liter opaque container that holds uncured resin for printing.
6. Zip ties: Fasteners used to secure the transfer tube to the resin pump.
7. Cable clip: A clip with an adhesive back that can be attached to the printer to keep the transfer tube in place.
8. USB-C cable (Resin Pumping System (Form 4) only): A cable that connects the pump to the printer for power and communications

Using the Resin Pumping System with SLA printers

1. Remove the stock cap from the resin container.
2. Attach the straw to the transfer cap. Push the straw into the opening in the bottom of the cap until it is fully seated.

3. Screw the transfer cap onto the resin container. Ensure it is properly seated and tightened to prevent leaks or spills.

4. Remove the resin card from the resin container. If you are using the Resin Pumping System (Form 3), separate the lower section of the card at the scored line.
5. Insert the resin card into the resin pump’s card reader slot. The card should fit snugly into the slot.

6. Connect one end of the transfer tube to the exposed barbed fitting on the resin pump. Push the tube onto the barbed fitting until it is flush against the flange at the base of the fitting.

7. Use a zip tie to secure the transfer tube to the barbed fitting on the resin pump to prevent resin spills.

8. Remove the blue silicone plug from the resin container’s transfer cap to expose the output barb and the vent hole.
9. Connect the other end of the transfer tube to the transfer cap’s output barb. For added security, you may optionally secure the transfer tube to the resin container with another zip tie.

10. Insert the resin pump into the printer’s cartridge slot.
• On Form 3L generation printers, the resin pump must be placed in the left cartridge slot.

11. Place the resin container next to the printer on a clean, level surface. Take care to not pull or pinch the transfer tube when moving the resin container.
12. Resin Pumping System (Form 4): Plug the integrated USB-C cable into the port on the back of the printer.

13. If the printer is powered on, it displays a message on the touchscreen and plays a notification sound once it detects the resin pump.

Once the resin pump is inserted into and recognized by the printer, you can start printing.

The transfer tube and pump tube cannot be reused when changing materials for printing with the Resin Pumping System. Transfer tubes and pump tubes are available for purchase from Formlabs on the Formlabs store. The replacement tubes are the same for both the Resin Pumping System (Form 3) and Resin Pumping System (Form 4).

Using the Resin Pumping System (Form 3) with the Form Auto

When installing the resin pump into a printer mounted on a Form Auto, attach the included cable clip to the back of the printer to secure the transfer tube in place. Be mindful of the orientation of the transfer tube. Take care not to tangle or pull on the tube when inserting the resin pump into the cartridge slot.

Resin containers and straw caps are made of high-density polyethylene (HDPE) and polyethylene (PE) and can be recycled with plastic household waste once fully cleaned. The transfer tube is not recyclable and should be disposed of with regular household waste.
