as CHL said, don't scan impressions. it just doesn't work. the labs that have done it have spent immense time dialing in every little thing to make it work. I used to work for a lab in Mormon Central that went all digital after opening back up from COVID. seemed to be doing well last I saw, but they also spent a solid year plus working on dialing everything in to make it work. they were also picky enough that the doctors who were sending them physical impressions were actually taking good impressions, so they had that working for them too.
if you're going to use the printer as a producer, then you're going to have to spend some money to make it worth while. whilst formlabs is relatively cheap, and accurate, you dont get the speed. the printer we have cost us about $25k. prints the same amount of models that we were printing on the Form2, in 1/10 the time.
shop, shop, and shop some more. if you've never used a printer before, then definitely get a cheapo one from amazon to just try until you get comfortable with it. if you're familiar with resin printers, then go all in, and get something that is going to last you.
