Cleaning Your Printer

When you are finished printing using a resin, clean your printer and dispose of your waste properly. If you still intend to print during this session with the same resin, you usually can reuse your resin and IPA.

1. Clean your Build Platform

On the bottom of your build platform, some residue from the previous print will likely remain. Remove all solid debris from the platform with a pair of tweezers, and then you may reuse the remaining resin.

Pick up the build platform and hold it angled above the partially full resin vat. Scrape the resin off of the platform into the vat with long strokes of the scraper.

Warning!

Do not reattach the build platform at this time. The next step involves removing the vat, which normally protects sensitive components, such as the projector. If the build platform is attached loosely or improperly, it may fall and severely damage the printer.

2. Store or Dispose of Resin

Make sure that the remaining resin is acceptable to for reuse in the future. Do the following before storing your resin:

  • Check the color of the previous print for irregularities. For a normal print, the color of your resin should remain consistent throughout the entire print. If the previous print has darkened or browner locations in the print, it is possible the resin density is inconsistent or that there is some contamination. The print itself may still match your need and you may continue using it, but Ackuretta recommends disposing of this resin if you see these inconsistencies.
  • Make sure your resin is watery. Take a scraper, spatula, or spoon and dip it into several different areas of your resin. Pour out the resin slowly back into the vat. The resin should have a thin, watery consistency. If the resin has thickened or it falls off in strings, UV light may have dispersed over the resin and started to harden it. This may cause your next model to print inconsistently or to become unstable. As such, Ackuretta recommends disposing of your resin in this case.
Storing Unused Resin from the Vat
  1. Find a dry, opaque empty bottle that has not been used for any other purpose.
Note

Do not use a bottle with another resin, or even the original resin bottle that you poured this resin from. This is to prevent resin cross-contamination.

2. Place a funnel on the mouth of the bottle and put a wire filter inside the funnel.

3. Hold the vat diagonally over the bottle and slowly pour the resin into the funnel. The watery resin will pass through the filter, and any sediments or debris will be trapped by the filter.

4. Label the bottle with the type of resin used and the date that you stored it.

5. Use a tissue dipped in IPA solution to wipe down the funnel.

6. Clean the filter into the ultrasonic cleaner with your previously used IPA for about 1 minute. For more information about using the ultrasonic cleaner, see Cleaning and Drying the Print.

7. Remove the filter from the ultrasonic cleaner and clean it with a tissue dipped in IPA solution.

3. Prepare a Container for IPA Disposal

Choose a plastic container to use specifically for waste IPA storage. The container should be dry and have a tight seal. Ensure that you have enough space in a storage cabinet for this container, and that the container will be kept away from any heat, flame, or sparks. The container should not be stored in a cabinet alongside strong oxidizers, acetaldehyde, chlorine, ethylene oxide, acids and isocyanates.

Warning

IPA is a controlled chemical in many countries and must be disposed of properly. Check the federal safety regulations and disposal methods in your country.

When storing IPA, whether for disposal or for use, keep all containers far away from any sources of heat, sparks, or flame.

4. Clean Your Vat

Pour a small amount of IPA into the vat, and tilt the vat so the IPA reaches all locations. Use a rubber spatula to push the IPA out into your IPA disposal container.

5. Reattach the Vat to the Machine

Slide the vat above the thumb screws, and pull it back into place on the machine. Twist the thumb screws clockwise until they hold the vat securely.

6. Reattach the Build Platform

Slide the build platform onto the machine arm. Twist the thumb screw clockwise to hold the platform securely.
