Replacing an empty resin cartridge with a full one of the same type:
More information on the resin system and changing a cartridge can be found on the webpage “Formlabs Resin Tank Information” through the Formlabs website.

Both the resin cartridges and build platforms are cross compatible with both the Form 2/3 as well as the newer Form 3 3D printers however the build tanks are not interchangeable. Types of resins are distributed between the Form 2/3 and Form 3 based on frequency used as well as which benefit from the low force SLA process employed by the Form 3 and should not be swapped without consultation with the staff.

  1. Remove the empty resin cartridge:
    1. Close the vent cap at the top right of the resin cartridge to prevent resin from spilling out once removed
    2. Hold the cartridge handle and lift to remove from the Form 2/3. Store the cartridge upright with the valve cover installed to protect storage surfaces from resin.
  2. Insert a new resin cartridge:
    1. Shake and rotate the new resin cartridge to ensure that the resin is mixed thoroughly.
    2. Align the cartridge with the opening at the back of the printer. Push down on the cartridge handle until the top of the cartridge is level with the printer.
    3. Press open the vent cap to ensure the resin tank can fill correctly

New build tanks should be marked off when a new resin cartridge is put into rotation. This allows us to keep track of the wear on the build tanks and troubleshoot the printers more easily. Each new build tank is marked with a countdown of the number of liters remaining. Continue to numbers off the list as new resin tanks are put into use.

Switching a printer from one type of resin to another

More information on the resin system and changing a cartridge can be found on the webpage “Formlabs Resin Tank Information” through the Formlabs website. This includes videos and animations.

  1. Remove the build platform - this prevents resin from dripping onto the glass
  2. Remove resin cartridge:
    1. Close the vent cap at the top right of the resin cartridge to prevent resin from spilling out once removed.
    2. Hold the cartridge handle and lift to remove from the Form 2/3. Store the cartridge upright with the valve cover installed to protect storage surfaces from resin.
  3. Remove the resin tank
    1. Hold the front tabs of the resin tank
    2. Gently pull the front tabs of the resin tank to release the tank feet from the tank carrier. The Resin Tank LT wiper ejects during removal.
  4. Cover the resin tank and store on the left side of the fume hood
  5. Insert the resin tank for the resin that you plan to use
    1. Lift the Form 2/3 orange cover. Use the tank grips to hold the Resin Tank LT, with the wiper resting inside the tank. If the tank contains resin, cover the tank with the plastic lid to align the wiper and minimize the risk of spills during insertion.
    2. Align and insert the four small feet of the resin tank into the corresponding slots in the tank carrier on the printer.
    3. Hold the front tabs and carefully push the tank until the tank feet lock into the slots on the tank carrier. Check the touchscreen display to confirm that the Form 2/3 detects the tank. The Form 2/3 will only detect the tank when the tank is fully inserted.
  6. Lock the wiper blade
    1. Align and insert the wiper foot into the wiper mount.
    2. Push the wiper toward the tank.
    3. Ensure the wiper foot is securely locked into the wiper mount.
  7. Insert resin cartridge:
    1. Shake and rotate the new resin cartridge to ensure that the resin is mixed thoroughly.
    2. Remove the protective valve cover from the underside of the cartridge. Use the cover to protect the bite valve during storage.
    3. Align the cartridge with the opening at the back of the printer. Push down on the cartridge handle until the top of the cartridge is level with the printer.
    4. Press open the vent cap to ensure the resin tank can fill correctly.
  8. Replace build platform
  9. Make sure that all of the resin tanks are correctly labeled.

New build tanks should be marked off when a new resin cartridge is put into rotation. This allows us to keep track of the wear on the build tanks and troubleshoot the printers more easily. Each new build tank is marked with a countdown of the number of liters remaining. Continue to numbers off the list as new resin tanks are put into use.

Safety Concern

Safe Operation Procedures Review

  1. Check resin cartridge and tank, make sure build material matches and is desired material.
  2. If resin is not desired material, disconnect wiper at build tank, remove build plate by sliding towards front of fume hood. Remove cartridge, cap valve on bottom and close valve on top of cartridge. Replace build tank, wiper, and cartridge with desired material.
  3. Launch Preform on Ultimaker computer
  4. Import desired STL
  5. Select “one click print” in the top left corner menu, change position, orientation, resolution and support as desired (note: that Preform will report on print ability of model, changing part rotation can affect print ability.
  6. Select print (orange button) from top left menu
  7. Select desired printer
  8. Press button on Formlabs printer to start print

Post Processing

  1. Excess resin should be removed from the build tray and part with IPA over a waste container.
  2. Place build tray and part in the Form Wash for 20 to 30 minuets (part can be placed individually within basket if necessary
  3. Allow 30 minuets for IPA to evaporate before placing part in Form Cure
  4. Set Form Cure time and temperature based on resin type, place part within form cure, wait for time to elapse
