Formlabs products perform best when they are well-maintained and properly cared for. For the best results, observe these Formlabs guidelines to clean and maintain your Form Wash.

• Inspect all parts after printing to determine the best washing process.
• Operate the Form Wash only when the wash bucket is filled with a sufficient amount of clean solvent.
• Do not wash loose parts in the wash bucket without the basket as this may damage the internal components.

Isopropyl alcohol (IPA) is suitable to clean most surfaces, including cured and uncured resin. When wiping the outer surfaces, use a non-abrasive cloth and a general purpose cleaner. Other materials may scratch the outer lid.

Dissolved resin accumulates on the walls of the wash bucket. Periodically, while replacing the solvent, clean out the wash bucket to remove these resin deposits. Rinse the wash the bucket before refilling it with fresh solvent, then wipe the wash bucket with a paper towel.

To maintain the outer lid:

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

To maintain the display:

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

If any liquid resin spills on the display or knob, promptly clean and inspect the Form Wash to minimize any cosmetic or functional damage to the device. If you experience a resin spill, document the problem with photos and clean the unit as best as possible. Contact Formlabs Support or your authorized reseller as soon as possible.

Form Wash (1st Generation)

Before starting a wash cycle, ensure that the solvent level in the wash bucket is between the minimum and maximum fill lines. If the solvent level is below the minimum fill line, parts washed on the build platform may not be fully immersed in the solvent during the wash.

Form Wash (2nd Generation)

The Form Wash (2nd Generation) features a maximum fill line of 15 L and three different solvent fill levels (7 L, 10 L, and 14 L) that correspond to the three build platform mount arm positions. When using the Form Wash (2nd Generation) make sure that the solvent volume reaches the build platform surface.

The level of resin concentration of the solvent will increase gradually as more parts are cleaned in the solvent, reducing the effectiveness of the wash. Measure the resin concentration of isopropyl alcohol (IPA) or tripropylene glycol monomethyl ether (TPM) with a hydrometer.

The hydrometer packaged with the Form Wash does not measure the correct range of specific gravity for use with Formlabs Resin Washing Solution. A hydrometer that can measure a specific gravity of 0.900–1.000 should be used instead. The specific gravity of fresh Formlabs Resin Washing Solution is 0.94. When the specific gravity of the used Resin Washing Solution is above 0.975, it will not be fully effective as a final wash.

For printing operations without access to a solvent recycling system, note that safe and appropriate disposal methods of used solvent will vary by location. Whether replacing IPA or TPM, consult the safety data sheet (SDS) from the solvent supplier as the primary source of information.

Formlabs occasionally releases new firmware versions for the Form Wash to introduce features and critical updates. Keep the firmware of your Form Wash up to date to ensure optimal performance.
