Clean Parts With Ultrasonic Cleaner

NOTE: Read all documentation that came with your ultrasonic cleaner for operating and safety instructions.

Always wear 100% nitrile gloves whenever handling anY uncured printed part, as well as when handling any solvent used to clean such parts.

CAUTION: Ensure that your ultrasonic cleaner is properly rated to use flammable solvents. Failure to do so could present a fire hazard.

The following instructions are recommendations for using an ultrasonic cleaner to clean parts made with FabPro™ materials. For instructions for NextDent®materials, please see your material's Instructions for Use.

  1. Label your glass or steel containers as "1st Bath" and "2nd Bath."
  1. Wearing nitrile gloves, place the printed part(s) inside 1st Bath container. Pour recommended solvent (seeCleaning Chart) into the container until you completely submerge the printed part. Dirty solvent may be used for this first bath.

    NOTE: You may use "dirty" solvent for this first part bath. Solvent is considered "dirty" when it has reached the maximum number of prints specified for your material in theCleaning Chart. You may use "dirty" solvent for an additional number of prints equal to the "maximum number" specified in cleaning chart. For example, for FabPro Proto GRY material, you may use "dirty" IPA or EZ rinse C to clean 10-12 parts, for a total of 20-24 parts cleaned. Once you have reached this maximum again, you must discard the solvent/material mixture according to all local, state, and federal regulations.
  1. Place 1st Bath container inside the ultrasonic cleaner.

  1. Follow the instructions in your ultrasonic cleaner's User Guide to power it on and begin cleaning. Follow the instructions in theCleaning Chartfor how much time is required for this first bath.
  1. After the cleaning cycle has finished, remove the printed part from the ultrasonic cleaner using nitrile gloves. You may wish to use shop air or an air compressor to dry the part in between cleanings, as this is an effective method for getting one solvent off the part before cleaning it with another.
  1. For 2nd Bath container, follow the instructions above from Steps 2-5, but this using "clean" solvent. Follow the instructions in theCleaning Chartfor how much time is required for this second bath.

NOTE: You must use "clean" IPA for the second part bath. Solvent is considered "clean" if it has been used to clean less than the maximum number of prints specified for your material in theCleaning Chart. Rinsing with dirty solvent in this step risks not completely cleaning the part of uncured liquid material.

TIP: Once you have used the "clean" IPA to wash the maximum-allowed parts, you may then use it for the first, "dirty" part bath (see Step 2).
  1. Inspect the part(s) closely to make sure no liquid material remains. Pay particular attention to shiny areas, as they may indicate the presence of liquid material. If you are unsure if liquid material remains, it is best to repeat Step 6.

NOTE: Be sure that you place lids on Containers 1 and 2 when they are not in use.

NOTE: Solvents must be disposed of according to all state, local, and federal regulations.
