I'm not trying to talk you out of it but just be aware that resin wont be your only expense involved in printing. I'm on my third Form 1 and I would like to "upgrade" to the F1+ but not willing to pay $750 for what I see as a repair and not an upgrade. That aside the resin vats PDMS layer needs replaced constantly so you will have to either keep buying new vats or replace the PDMS yourself with a solar panel encapsulating kit. The PreForm software has improved immensely but isn't quite perfect yet, but getting close. Support from Formlabs is painfully slow but usually acceptable. I have had a 50% print success rate at best, but its currently much much worse. It is amazing when it works but unfortunately that has not been often and so has cost me alot more time and money than I ever suspected or hoped. I dont know that there are any truly viable alternatives at this time though, probly a couple more years before the Form 1 sees any real competition.
