Cleaning and maintaining the Form Cure L

Cleaning and maintaining the Form Cure L

Debris or contaminants may collect in the Form Cure L or on the machine’s internal surfaces over time, particularly if printed parts are not fully dried before post-curing. In order to preserve the reliability of the Form Cure L, it is important to regularly inspect and clean the machine’s various components and assemblies. The standard maintenance cycle for cleaning the Form Cure L is every one to three months of use.

Danger:

Fire hazard: IPA is flammable. When cleaning the Form Cure L, allow isopropyl alcohol to fully evaporate before starting a post-cure cycle.

Warning:

Wear personal protective equipment (PPE) when performing maintenance tasks. Use tools only as described.

Notice:

  • Formlabs provides instructions to advise skilled and unskilled persons in installing, operating, and maintaining the Form Cure L. The Form Cure L shall only be maintained by a qualified and trained person.
  • Do not open the Form Cure L and/or investigate internal components unless under the guidance of Formlabs Support or a certified service provider. Contact Formlabs Support or an authorized reseller for any additional guidance.
  • Unauthorized disassembly or repair procedures may damage the machine and void the warranty.

Schedule of maintenance

Follow the cleaning schedule to inspect, clean, and maintain your Form Cure L on a regular basis.

Maintaining the turntable

The Form Cure L relies on the turntable’s rotation to expose part surfaces to even amounts of light and heat. The turntable must have sufficient clearance to continue rotating.

To maintain the turntable:

  • Periodically lift the turntable to inspect underneath it for small pieces of cured resin. Remove particles of cured resin from above and below the turntable to ensure the turntable can rotate without interruption.
  • Clean the turntable and the surface underneath as needed.
  • Use isopropyl alcohol to clean the turntable or the base if necessary, and allow isopropyl alcohol to fully evaporate before starting a post-cure cycle.

Maintaining interior surfaces and the light diffusers

The internal surfaces of the Form Cure L are covered in a reflective coating that reflects the light from the LEDs to ensure that parts post-cure evenly. Additionally, the primary 375 nm and 405 nm LEDs and the secondary white LEDs in the Form Cure L are covered by frosted light-diffusing panels. These light diffusers spread the light from the LEDs and ensure that parts post-cure evenly. If the reflective coating or light diffusers are damaged or covered, parts may not post-cure properly.

Resin hardens during post-curing. Cured resin blocks light and must be removed. If parts are washed but not fully dry before post-curing, certain washing solvents, such as tripropylene monomethyl ether (TPM), may evaporate and form deposits on the interior surfaces of the Form Cure L. These deposits cloud the reflective coating and prevent parts from post-curing properly.

To maintain the interior surfaces of the Form Cure L:

  • Visually inspect the internal surfaces and light diffusers of the Form Cure L for traces of resin, cracks, or other damage.
  • Clean the reflective coating and light diffusers as needed. Use isopropyl alcohol to clean the reflective coating and allow isopropyl alcohol to fully evaporate before starting a post-cure cycle.

Maintaining the door

The Form Cure L door has double walls to insulate the post-cure chamber and internal surfaces that reflect light. A damaged or dirty door may reduce the effectiveness of the Form Cure L.

To maintain the Form Cure L door:

  • Visually inspect the door for traces of resin, cracks, or other damage.
  • Clean the door with a non-abrasive microfiber cloth and soapy water or a general purpose cleaner, such as glass cleaner.

Maintaining the touchscreen

The LCD capacitive touch user interface displays post-cure cycle information, settings, and error messages. Damage to the touchscreen may prevent you from interacting with the Form Cure L and starting a post-cure cycle.

To maintain the Form Cure L touchscreen:

  • Visually inspect the touchscreen for any traces of resin.
  • Check that the touchscreen responds to inputs.
  • Clean the touchscreen with a non-abrasive microfiber cloth and a general purpose cleaner, such as glass cleaner.
