I’ve had my printer just a bit under a year and I print almost weekly (ALOT more in the beginning). I’ve had to replace the wash three times (?), and I’ve used ~ 3.5 gallons of alcohol. I use a spray bottle to clean everything up (tools, work area, build plate, + the occasional tank clean), so I tend to use a lot as I don’t like resin hanging around. The cost isn’t much worse than a bottle of resin at $30 for 1gal on amazon so while it adds cost it’s not too much. You might also look into water washable resin but I have no experience with it so I can’t recommend it one way or the other.
Oh speaking up cleanup and build support removal don’t forget eye protection and maybe an n95 mask (the smell can be strong from both the resin and alcohol). You’re playing chemist here with some smelly chemicals.
I would love to hear the effects all those knobs have on the tone.
