Debris or contaminants may collect in the Fast Cure or on the machine’s internal surfaces over time. In order to preserve the reliability of the Fast Cure, it is important to regularly inspect and clean the machine’s various components and assemblies. The standard maintenance cycle for cleaning the Fast Cure is as needed.

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

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

To maintain the turntable:

• Inspect the underside of the turntable and the top of the tray for small pieces of cured resin. Remove particles of cured resin to ensure the tray sits flush on the turntable and 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.

The post-cure chamber of the Fast Cure reflects the light from the LEDs to ensure that parts post-cure evenly. If the post-cure chamber is damaged or covered in resin, parts may not post-cure properly.

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 Fast Cure. These deposits cloud the reflective coating and prevent parts from post-curing properly.

To maintain the post-cure chamber of the Fast Cure:

• Visually inspect the internal surface of the Fast Cure for traces of resin, cracks, or other damage.
• Clean the post-cure chamber as needed. Use isopropyl alcohol to clean the chamber and allow it to fully evaporate before starting a post-cure cycle.

The Fast Cure door seals the post-cure chamber and contains the UV light from the LEDs. A damaged or dirty door may reduce the effectiveness of the Fast Cure.

To maintain the Fast Cure door:

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

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 Fast Cure and starting a post-cure cycle.

To maintain the Fast Cure touchscreen:

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

The Fast Cure uses three UV LED assemblies to post-cure parts. The LEDs have an estimated lifetime of 1,500 hours. Once the LEDs reach the end of their lifetime, the Fast Cure displays a message to inform you that the LEDs need to be replaced.

If the LEDs are past their lifetime and require replacement, please contact Formlabs Support or your authorized reseller for details on how to replace them.
