Is this process really better than the one used in the Peachy printer? Peachy printer uses resin tank that is filled with salt water from the bottom (which raises the level continuously, resin floats on saltwater) and the UV curing is done from the top. One huge thing for the Peachy is that you can use any tank, and the size of the print isn't limited. Also, Peachy costs just $100.
Well here you only need a small tank relative to the finished print, also, you don't move the laser head, but only the parts of the item that has already been printed. Everything else stays still, meaning reduced vibration which seems to mean a really steady quality of print.
In Peachy, both the laser head and the print are fixed in place. So it doesn't have the usual moving parts at all (although it uses modulated laser mirrors instead of a projector for cost reasons).
