Noooo! 2 hours is way too long. Your prints are swelling and deforming with that long a soak. RTFM, my friend. I think Grey calls for 20 minutes of IPA soak, 10 mins in tank 1, 10 in tank 2.
I tend to agitate the IPA during rinse, either by pulling the wash basket up/down slowly or putting a lid on the tank and shaking it. This lets me reduce the IPA soak time by about half, which I need to do because many of the parts I print have very thin walls and 20 minutes is too long, they get soft and mushy.
I had a magnetic stirrer I made, but it went to magnetic-stirrer-heaven in a glorious cloud of magic smoke and I haven’t rebuilt it…
@Randy_Cohen yeah, I don’t usually leave my parts in for that long, I had to go out and my kid was bothering me to get it done.
Some little Minecraft figures he designed and wanted to drown in paint
Thanks for the info though, as I didn’t realise that too long in the IPA may be detrimental, cheers!
