Cleaning 3D resin printed objects is a crucial step in the post - processing of 3D resin printing. As a 3D Resin Printing supplier, I understand the importance of this process and am here to share some effective methods and tips with you.
Why Cleaning is Necessary
When 3D resin printing is completed, the printed objects are covered with uncured resin. This uncured resin not only affects the appearance of the object but also its mechanical properties. If left uncleaned, the uncured resin may continue to cure over time, leading to changes in the shape and dimensions of the object. Moreover, the presence of uncured resin can make the surface of the object sticky and prone to attracting dust and dirt. Therefore, thorough cleaning is essential to obtain high - quality 3D resin printed objects.
Cleaning Agents
There are several cleaning agents that can be used to clean 3D resin printed objects.
Isopropyl Alcohol (IPA)
Isopropyl alcohol is one of the most commonly used cleaning agents for 3D resin printed objects. It is effective in dissolving uncured resin and is relatively safe to use. The recommended concentration of IPA is usually between 90% and 99%. Lower concentrations may not be as effective in removing the resin.
When using IPA, you can pour it into a container large enough to submerge the printed object. Gently agitate the object in the IPA for a few minutes. You can use a soft brush to gently scrub hard - to - reach areas. After cleaning, remove the object from the IPA and let it dry.
Other Solvents
In addition to IPA, there are other solvents that can be used, such as acetone. However, acetone is more aggressive and may damage some types of resin or the surface finish of the printed object. It is important to test a small, inconspicuous area of the object first when using acetone or other strong solvents.
Cleaning Process
Initial Removal
Once the 3D resin printing is finished, carefully remove the printed object from the build platform. Use a spatula or a similar tool to gently pry the object off the platform. Be careful not to damage the object during this process.
First Rinse
After removing the object from the build platform, immediately place it in a container filled with the cleaning agent. This initial rinse helps to remove the majority of the uncured resin. For small objects, you can use a small container like a plastic cup. For larger objects, you may need a bigger container, such as a plastic bucket.
Agitation and Scrubbing
To ensure thorough cleaning, gently agitate the object in the cleaning agent. You can do this by swirling the container or using a mechanical agitator if available. For areas with stubborn resin, use a soft - bristled brush to gently scrub. A toothbrush can be a good option for small and detailed objects.
Multiple Rinses
It is often necessary to perform multiple rinses to completely remove all the uncured resin. After the first rinse, transfer the object to a container with fresh cleaning agent and repeat the agitation and scrubbing process. This helps to remove any remaining resin that may have been left behind in the first rinse.
Drying
After the final rinse, remove the object from the cleaning agent and let it dry. You can place the object on a clean, dry surface or use a paper towel to gently pat it dry. Make sure the object is completely dry before proceeding to the next step of post - processing, such as curing.
Post - Cleaning Curing
After cleaning, the printed object still needs to be fully cured. Curing is the process of exposing the object to UV light to harden the resin completely. There are curing chambers available that are specifically designed for 3D resin printed objects. These chambers typically use UV LEDs to provide a controlled and even curing environment.
Place the cleaned and dried object in the curing chamber and follow the manufacturer's instructions for the curing time and intensity. The curing time can vary depending on the type of resin and the size of the object.
Tips for Effective Cleaning
Wear Protective Gear
When handling cleaning agents such as IPA or acetone, it is important to wear protective gear, such as gloves and safety glasses. These solvents can be harmful if they come into contact with your skin or eyes.
Use a Filter
If you are using a large amount of cleaning agent, consider using a filter to remove the dissolved resin. This can help to extend the life of the cleaning agent and make the cleaning process more cost - effective.
Keep the Workspace Ventilated
Ensure that the workspace where you are cleaning the 3D resin printed objects is well - ventilated. The fumes from the cleaning agents can be harmful if inhaled in large quantities.
