There's an argument for getting a serious commercial printer like an Asiga, because you'll have access to serious product support for businesses, and I agree to a point, but you'll pay an incredible premium for that and not a whole lot more. Commercial printers produce better parts than a Phrozen will, but the difference isn't actually that big for most purposes, and you will often have just as big a headache getting good parts from dental printers as you will from a hobbyist or prosumer model- and if the Phrozen turns out to be a lemon, it doesn't hurt too much to just junk it and buy another, whereas a $30k printer can become a nightmare albatross around your neck if you get unlucky and your vendor is ****.
Higher-end printers can also cost significantly more to operate because of consumables, particularly the imaging hardware and the build trays. LCD-based printers like the Phrozen use an off-the-shelf smartphone/tablet screen to do the light exposure masking, so they're reliable and affordable because they're being manufactured in hundreds of thousands or million-tier quantities, you benefit from economies of scale. Replacing one is straightforward and won't cost too much.
In comparison, our Asiga DLP printers make use of a very expensive and specialized projector + mirror microarray unit that is manufactured especially for that product in small quantities. Replacements cost thousands of dollars, and the projector units often die quite quickly. And they need to be installed by an experienced specialist technician, which you will have to pay another large sum for. Asiga resin trays also cost a couple hundred a pop, and they use RFID tags to artificially limit their lifespans- they stop working after so many prints, even if the tray is in good condition and has more prints in it. With a Phrozen you can just replace the tray FEP membrane yourself indefinitely for 10 bucks a pop.
The far end of this spectrum are Carbon printers, which really do Just Work and produce great results with little effort. I love Carbons, as someone who prints parts and does not pay for the equipment. You'll also pay many thousands of dollars a year to *rent* them, no you can't buy them. I think an M3 Max is, like, 100-125k per year, before considering consumables, tray rentals, etc. For the cost of one Carbon for a year, you could build an enormous fleet of Phrozens with, like, 50x the capacity. Not that they're interchangeable like that, but my point is you can save an enormous amount of money by being willing to learn a new skill and figure things out for yourself.
