[QUOTE="tuyere, post: 367968, member: 26916"] FWIW I've actually had more scaling issues with expensive DLP printers than with LCDs, because the projector unit complicates things and if it's out of alignment you can get scale issues that vary across the plate and aren't fixable with the resin scale factor. We have that on our Asiga right now, the prints are too big at one end of the plate and too small at the other, it took me forever to figure out why we were having fit issues with some but not all of the parts from a printer despite the calibration/scale tests looking good (because they were dead-center on the plate and the models were elsewhere). Users generally can't service this kind of issue themselves. LCD printers are now good and cheap enough that the benefits of DLP printers are... declining, I'd say. I myself would definitely go with a Phrozen or similar prosumer-tier LCD printer over an Asiga or other dental DLP if I were setting up my own lab, and cost isn't the only factor there. [/QUOTE]
