I've used formlabs printers at work. They are great, but using them has persuaded me to not purchase my own. Most prints, I use three pair of disposable gloves. That resin and the IPA wash (which has a lot of dissolved resin) make really annoying messes. We've already lost one Form Wash due to people being careless and leaving the lid up. The IPA with resin will set over time.
You can't pour the stuff down the drain. One user tried putting really contaminated IPA in a tray and sticking it in our chemical hood to dissolve (while myself or the lab manager wasn't there to stop him). We had a surprise safety audit like we do on occasion and were cited for leaving this huge batch of flammable material out in the open.
We ended up getting a dedicated flammable cabinet for resin IPA. At the end of the week, I'll turn on the Form Wash and let it stir the wash IPA for a few minutes. While it's still stirring, I transfer it to a couple of three liter jugs and place them in the flammables cabinet. It sits for a couple of days and a lot of solids settle to the bottom of the container. Then the top 80%-90% of the IPA is carefully poured back into the wash chamber without stirring up sediment on the bottom. Fresh IPA is used to top off the wash. The cloudy wash in the bottom of the jug is poured into yet another jug. Once that jug is full, it sits for a week to settle in the flammables cabinet. We can usually capture the top 10% and pour it (through a filter) back into our main wash solution, the rest is capped and left exposed to light for several days/weeks to set, and then is disposed of in our hazardous waste.
Even with all of this settling to keep our wash solution as clean as we can, eventually, it will become too contaminated to use (formlabs recommends changing the liquid at a particular density).
It's a messy process and people still get gloves damp and touch the cure station and get resin prints everywhere. We leave IPA wipes on the counter and go though a pack of those every two weeks trying to keep the resin print area clean. I like the print quality and ease of getting a print. But after using the one at work, I decided not to get one at home.
Imagine how much messier the Saturn is if I tell you it's much messier than the FL
