Perform these maintenance actions every week:



Put on CLEAN GLOVES before proceeding.

Print Head Clamp Pot

Inspection Only

A clean clamp pot is important to ensure the proper seating of the platform.

  1. Remove the platform.
  2. Inspect the clamp pot on the underside of the build arm for any resin or debris that will affect functionality. Pay extra attention to critical areas that interface directly with the underside of the platform:
    • Circular metal area of the clamp pot
    • Recess for platform pin

If you find a dirty clamp pot with resin or other debris, do not clean the hardware yourself. Contact Carbon Support.

Platform NFC Antenna

Inspection Only

The NFC Antenna is what the printer reads to identify the platform. Keeping this clean is critical for printer operation.

  1. Remove the platform.
  2. Inspect the NFC antenna on the underside of the build arm for any resin or debris that will affect functionality. Pay extra attention to critical areas that interface directly with the underside of the platform:
    • Round area, shown here with the orange circuitry

Deck Clamp Pots

Inspect Deck Clamp Pots

Clean deck clamp pots are important to ensure the proper seating of the cassette.

  1. Remove the cassette.
  2. Inspect the 4 clamp pots on the deck for any resin or debris that will affect functionality. Pay extra attention to critical areas that interface directly with the underside of the cassette:
    • Black ring around hardware (sits slightly proud of the hardware)
    • Recess for cassette pin

Clean Deck Clamp Pots if Dirty

  1. First place the foam insert (included during shipping) or clean aluminum foil on the pedestal to keep any debris from falling into the printer cavity.
  2. Dampen a large swab with IPA, outside of the printer, and blot on a blue shop towel.
    • Do not apply IPA directly to the clamp pot.
  3. Clean the clamp pot to remove and resin and dust
    • Clean the metal surface and the raised black ring around the hardware
    • Clean the recess by inserting the dampened swab

If there is cured resin on a clamp pot, or you cannot get one fully clean, contact Carbon Support.

Heater Glass

The M3 / M3 Max printer comes equipped with two heaters to provide temperature control for highly viscous resins to improve their flow during printing. The heaters are covered with glass to prevent resin from accidentally dripping on heating elements and igniting.

The heater glass must be clean and free of any resin or particulates for normal printer performance.

⚠️ The heaters are connected to the power supply and power must be turned off for safety before servicing.



⚠️ Burn hazard: The heater may be hot. Allow to cool 15 minutes after last print before servicing.

Locate Heaters

  • Heaters reside at the front and back of the projection volume, below where the cassette sits.
  • Heaters sit partially underneath a short overhang of the deck.

Cleaning Heater Glass in Printer

Dust or small drips of resin may be cleaned without removing glass from the printer if you can reach the area.

  • Lightly dampen a blue shop towel with IPA, outside of the printer
    • Do not saturate the towel to the point of dripping solvent.
  • Reach into the opening, and wipe the heater glass with the towel, until it is clean, dry, and without streaks.
    • Use a light touch to protect the glass

Removing Heater Glass to Clean, Replace, or Secure

Larger resin spills, especially dirty glass, or damaged glass will need to be removed for cleaning or replacing. This video also shows how to properly secure the glass. If a resin spill has dripped beyond the glass itself, contact Carbon Support.



1. Locate two glass-securing spring clips 2. Push and rotate clips outward to free glass 3. Carefully remove the glass cover - Tilt glass to remove it from printer cavity - Be careful to avoid the IR sensor when removing 4. Clean both sides of glass with IPA - Dampen a blue shop towel - Until clean, dry and streak free 5. Carefully replace glass inside printer's heater - Tilt glass to replace it in printer cavity - Ensure glass rests on metal clips on each side of reflector - Press down metal bar at center of assembly to sit below glass - Hold glass in place with thumb - Push and rotate clip back over glass - Push and rotate 2nd clip back over glass

The heater glass is tempered for safety and to increase durability, but it is still susceptible to breaking if not handled with care.

The printer will not operate if the heater glass has not been properly secured in place.

Spill Window Glass

The light engine projects light through the spill window onto the cassette window to cure resin. If the spill window is not clean, it may affect part quality.



Inspect Spill Window

Inspect the light engine spill window inside the projection volume for any smudges, resin, dust or debris that will affect print performance.

Clean Glass if Dirty

  • Lightly dampen a blue shop towel with IPA, outside of the printer.
    • Do not saturate the towel to the point of dripping solvent.
  • Reach into the opening, and wipe the spill window glass with the towel, until it is clean, dry, and without streaks.
    
  • If cured resin cannot be removed in this manner, contact Carbon Support.

Printer Door

Cleaning the door weekly is important to ensure the door retains anti-static properties by using an anti-static acrylic cleaner. In addition, cleaning removes dust, fingerprints, and small amounts of resin.

Ensure the printer door is in the closed(up) position.

Never use a dry cloth or alternative cleaners to wipe the door.

Using a dry cloth or unapproved cleaners can create a static electric charge on the door. This door had a static charge and pulled liquid resin dripping from completed parts onto the inside of the door.

This can cause resin to reach prohibited areas.

Be sure to click on the image to the right to see the resin droplets on the door.

To clean the white front panel:

  1. Dampen a lint-free polishing cloth with Brillianize (anti-static acrylic cleaner) outside of the printer.
  2. Wipe the white outside panel on the service door.

Never use acetone to clean white panels.

E-Stop Check

To ensure the emergency stop is functioning correctly, engage the e-stop to confirm the printer enters a halted state. Then disengage the e-stop and restore system power.

Touchscreen Display

It is strongly recommended to apply a screen protector to the printer's touchscreen display. With or without the screen protector, you must clean the screen weekly to prevent a resin build-up.

Clean Touchscreen Display

  1. Avoid starting a print accidentally during cleaning.
    • Remove the platform or
    • Make sure the print queue is empty. Touchscreen will say Printer is available when queue is empy.
  2. Lightly dampen a blue shop towel with IPA and wipe screen with protector until clean.
    • Do not use IPA wipes, which have a high water content.
    • Do not use acetone.
