I can’t get Everclear in California, and it appears as though denatured alcohol has been banned as well by the all-knowing powers-that-be in this state. How am I going to thin shellac without denatured alcohol?
Anyway, with the Yellow Magic 7, I have done an IPA rinse after the YM7, but it’s not really necessary in my opinion. With the white Peopoly resin, using IPA to clean the part after post-UV it has a dull finish. With the YM7 there are some shiny areas left, which I’m guessing means there was some uncured resin on the surface when I put it in the curing vat. I think this can be solved by extra time in the YM7 or longer ultrasonic cleaning time. Currently I have my ultrasonic set for its max time which is 480 seconds. A manual cleaning with a small paint brush should accomplish the same thing.
I then do a water rinse and put it in my UV curing vat. My vat consists of an 8-quart stainless steel stock pot from Walmart ($7) and a wooden lid I made to hold the Peopoly UV curing lamp. I submerge the part in water in the pot and let it run for an hour or two. I still need to get a timer to control the curing time better.
This pot replaced my 3D printed curing chamber because I wanted to try submerged in water curing and the 3D printed chamber was too small.
After this process, the part may still be a little tacky, but that goes away after a day or so.
