This may be a stupid question, but I did not use my Formlabs Form 2 for more than 1 year. In the basic wash station, there is still a mixture of resin and IPA. Since I placed a little weigth on top of the wash bottles, only a little bit of the liquid did evaporate.
Now the question:
Can I use the left over liquid in the wash station? Is it maybe more toxic than before? Does the resin in the IPA change in some chemical way after all this time? Just asking. Thanks!
