Formlabs Resin Washing Solution is non-flammable per GHS classification, mitigating storage and environmental health and safety concerns. Wear disposable non-reactive gloves (nitrile or neoprene) when working with Formlabs Resin Washing Solution.

Formlabs Resin Washing Solution can be used with the Form Wash V2 or the Form Wash L.

To wash parts in Formlabs Resin Washing Solution:

1. Fill your wash containers. Fill the wash bucket (e.g., of your Form Wash or Form Wash L) with Formlabs Resin Washing Solution. Fill a separate container with water. Ensure the container is large enough so that printed parts can be fully submerged in water and that the container has a lid. Alternatively, IPA can be used instead of water for faster drying times.
2. Wash your printed parts as you would with IPA. Follow the guidelines in our support article Form Wash/Form Wash L time settings as a baseline.
3. When the wash cycle is complete, move your prints to the secondary container and let them soak in water for 30–60 seconds. No agitation is required.
• Ensure the parts are rinsed within eight hours of washing with Formlabs Resin Washing Solution. If parts are wet with Formlabs Resin Washing Solution, they may swell and have reduced accuracy and mechanical performance.
4. Let the prints air dry. The parts will regain their normal appearance as they dry. Air drying takes 4–6 hours. Use compressed air to accelerate dry time to 30–60 seconds or a fan for parts to dry in 30–120 min.

5. Place the parts in the Form Cure or Form Cure L to finish post-processing. When post-curing, follow the recommendations for your resin for best results.

Cleaning the build platform

If the build platform has also been washed with Formlabs Resin Washing Solution, clean the build platform thoroughly before using it again.

1. Dry the build platform with a clean paper towel.
2. Remove any remaining resin or solution residue from the build platform using a paper tower wetted with IPA, then wipe the platform dry again.

Formlabs Resin Washing Solution has twice the longevity of IPA and minimal evaporation, leading to less frequent top-offs and full changeouts of washing solution. If a thin film of resin remains on printed parts after washing with the solution, the solution is overly saturated with resin and should be replaced.

Form Wash L V1 and Form Wash L V2 units with firmware version 1.4.0 or later can track the saturation of your Resin Washing Solution using the solvent monitor.

Alternatively, monitor the saturation of your solvent using 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, such as this one sold by Cole-Parmer. 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.

The water bath loses effectiveness when it is oversaturated with dissolved Formlabs Resin Washing Solution. Replace the water regularly and dispose of the water-solution in accordance with local regulations.

Spilled Formlabs Resin Washing Solution does not present an immediate fire or health hazard, but it does leave an oily residue that can be slippery. The solution evaporates very slowly, so the spill won’t dry by itself.

To clean up a Formlabs Resin Washing Solution spill:

1. Put on a pair of disposable nitrile gloves.
2. Absorb excess solution with paper towels.
3. Clean up any remaining residue using wet paper towels.
4. Dispose of any tools used to clean up the spill (paper towels soaked with the solution, gloves coated in solution) with non-flammable hazardous waste according to local regulations.

Over time, Formlabs Resin Washing Solution accumulates dissolved liquid resin, which reduces its efficacy. For best surface quality, replace the solution once parts do not come out well.

Disposal

To safely dispose of contaminated Formlabs Resin Washing Solution:

1. Consult the safety data sheet as the primary source of information.
2. Research your local regulations for non-flammable hazardous waste disposal. This will most likely involve hiring a waste disposal service. For smaller amounts, check with your local waste disposal service to see if they have any suggestions for removal.
3. Provide your waste disposal service with the Formlabs Resin Washing Solution SDS and let them know that your waste also contains small amounts of methacrylated monomers and oligomers (unpolymerized plastic resin) and trace amounts of photoinitiator. Have a copy of the Formlabs resin safety data sheet (SDS) on hand in case the disposal service attendant needs more information.

Recycling

The Formlabs Resin Washing Solution container is made of high-density polyethylene (HDPE). Empty containers of Resin Washing Solution can be recycled in accordance with local regulations.

Formlabs resins

Formlabs Resin Washing Solution 也未经测试或验证可安全用于以下树脂：

• Alumina 4N Resin
• Castable Wax Resin
• PU Rigid 650 Resin
• PU Rigid 1000 Resin
• Flame Retardant Resin
• Flexible 80A Resin
• Flexible 50A Resin Powder
• Silicone 40A Resin
• 用于生物相容性应用的所有 Formlabs 树脂（如 BioMed 树脂和牙科树脂）

Formlabs 不建议使用 Resin Washing Solution 清洗 Tough 树脂家族的打印部件，因为这会导致部件表面粘性：

• Tough 1000 Resin
• Tough 1500 Resin V2
• Tough 2000 Resin V2

使用所有其他 Formlabs 树脂打印的部件（如通用树脂和 Alpha 树脂）均可使用 Formlabs Resin Washing Solution 进行清洗。

Finish Kit

Formlabs Resin Washing Solution 不适用于 Finish Kit 漂洗桶，但可在水浸泡过程中使用。

Form Wash V2 和 Form Wash L

Formlabs Resin Washing Solution 可与 Form Wash V2 和 Form Wash L 清洗桶配合使用。

Form Cure 和 Form Cure L

Form Cure 在使用时不排气，因此任何蒸发的溶液都会在加热器、风扇和内部表面凝结。如果将仍带有 Formlabs Resin Washing Solution 的打印部件放入 Form Cure 中，溶液会从打印部件上蒸发并凝结在 Form Cure 和 Form Cure L 的内表面上，偶尔会导致反射表面浑浊。因此，在打印部件充分干燥后（无论是用 IPA、TPM、水或是 Formlabs Resin Washing Solution 清洗）再放入 Form Cure 或 Form Cure L 中。

Formlabs SLA 打印机

请勿使用 Formlabs Resin Washing Solution 清洗您的 Formlabs SLA 打印机，尤其是光学器件表面。
