Optical clarity of splints is good, despite blueish tint. Letting it fall to floor (from peak height 2.3 meters) does not do anything, but throwing splint/biteguard to a concrete wall with full force.. it did something :-D
Different materials have different prices. Because of possible Finnish competitors reading these forums, i don't want to enclose exact prices in these "semipublic" threads.
To my experience it is the time save that matters most. You can design eg. occlusal splint in 15 mins (and it will fit, but it is still crappy),but it takes a bit longer to do good job. I talked to a guy who did those manually in 1.5 hrs per item. But now, working time more like ~30mins to design + 15-30 mins for finishing (atm we use normal articulator to check bite, do some drilling and then polishing) + 10 mins to take finished items from printer and prep the printing surface (clean it) for new job. OFC printing takes time, but it does not stop you from designing new things.
