What are the expenses of an SLA printer, are the prints more rigid than PLA and how is handling the liquids practically ?

The resin is a lot more expensive than filament, which is one reason I like to make delicate, open things with it. The prints are kind of soft when they first come out, but after some UV curing (leaving in the sun, for example), they get hard and even brittle. They can sometimes break and in fact these extremely delicate models do sometimes break if you're not careful removing the supports. You have to be gentle. They clean up really nicely though, and you can sand the prints afterwards and then polish with mineral oil to get them really transparent. As for handling the liquid, you need to make sure not to get it on your skin. It's not bad once you get the hang of it but it's a bit scary at first. You just have to use gloves, clean things up religiously, etc.
