Molbot & maesebit & bottenus,

Sorry it took so long to get in on this thread.

I do the following post cure procedure:

1. I remove the stage with product and place into a container.

2. I then fill the container with isopropyl alcohol until the design and stage are covered.

3. I gently swish the container with contents around. This tends to loosen liquid resin.

Note 1: Prior to using the ultrasonic cleaner I run it for 3 minutes to degas the water. This allows the water to work perfectly.

Note 2: Ultrasonic cleaners and isopropyl alcohol can produce a highly explosive gas. No sparking electronic/electrical device nearby. No open flame. I run an exhaust fan when the ultrasonic cleaning is going on. If you don’t have an exhaust fan, use a regular fan to blow air over the ultrasonic cleaner towards a window.

4. I then place the container into an ultrasonic cleaner filled with water and run it for about 60 to 90 seconds. I have run it for as long as 3 minutes, but 60 to 90 seconds works for me.

5. I remove the container and contents and gently swish the alcohol in the container again.

6. I drain off the isopropyl alcohol (heavily saturated with resin) from the container into a 2nd container.

7. I then wash the the stage and content with ambient temperature water using a gentle spray. I do this until I don’t see any more liquid resin.

8. Finally, I gently dry the stage and design using a can of air (keyboard cleaner).

9. At this point I place the stage in the ultrasonic side of the machine and start the final post cure process.

10. Finally, I place the second container with the used alcohol/resin outside in the sun to dry out so I can dispose the used resin legally.

On a second note, I only run the exposure times as suggested. The MiiCraft support team informed me that exposing too long can cause the resin to swell.

I hope all this is of some use to somebody.

I don’t have the time to be on the forum all the time so if you ask a question, I might not get back to you for some time. Please be patient.

On a third note, can the person who runs the forum clean up threads with unrelated junk. What a complete waste of time.
