Not sure what 4 doors you are refusing to see, but I think your basic understanding of how a print is formed may be wrong.
Yep, you are missing something. Yes, saline solutions are considered quite harsh for exposed mechanisms. However the saline is not being exposed to the mechanisms here. The resin floats on top of it and it is only touching at an interface layer at the bottom of a pool of resin. The resins being used are a UV curing epoxy(generally) that exhibits minimal water absorption. Most of the time, the water issue with FDM plastic extruders comes into play when they are heated. This design uses no heat. The uv is a collimated laser spot, not a widebeam of UV light.
Nope, you got it all wrong here. The print begins with a pool of resin on a stable base(the wire mesh or a layer of aquarium rock, etc) that hold the print in place. as the Z height increases, the saline is pumped(dripped) UNDER the liquid resin to raise it up. There is no solid layer being raised. the resin being used is just slightly less dense than the saline solution, so it floats on top, allowing the laser to hit the resin and cure a solid area, then the saline raises a bit and liquid resin flows over the edge and creates a new liquid layer ready for curing. The saline acts as both a Z layer mechanism and as a support mechanism for overhangs and such.
Sorry you got burned by another "company" that used Kickstarter style methods to defraud you. That is one of the hazards of such a system. That is also the reason why I think Peachy is legit. They are trying to make a system that doesn't cost two arms and a left testicle. If they were only trying to defraud you, they would be aiming for a bigger payday.
