It’s something that I often wondered. Acetone, even diluted as nail polish remover, does a great job of cleaning prints and, unlike IPA, doesn’t leave the piece with an awful smell.
Is it mainly price, or are there other reasons?
It’s really easy to fuck up and have it melt more than you intended. And with resin prints, specifically, there’s not really much needing to be cleaned up like with FDM printing. I prefer to just sand them if there happens to be any burs or whatever.
Really? I’ve been using it and never had any problem with the resin prints “melting”, getting too brittle/soft or break down in any form from over exposure to it
And with resin prints, specifically, there’s not really much needing to be cleaned up like with FDM printing.
Uh, I think you got it backwards, you have to clean the excess resin of a SLA print, while FDM is ready once it’s fully cooled, sanding optional
People who are actually in the know don’t use IPA. Several gallons of denatured alcohol can be had for a fraction of the price of IPA. It’s simply the less efficient but more commonly known chemical for the job.
The denatured alcohol you typically find in the the US contains a lot of methanol. It’s much more toxic than IPA.
Methanol is only a bigger issue if you drink it…unless you were drinking your isopropyl alcohol that’s not a very big concern.
You can absorb it via the skin too.
