Haha those are pretty cool and quick but there are the usual issues with that method of printing. The biggest being that the light source used to harden the resin is probably controlled by a DLP mirror like all the rest, so that means the resolution is limited to the size of the DLP chip. Let's say it is 2000x2000 resolution (which I think is on the high side), that means that in a standard 200mmx200mm build area you only have 0.1mm of precision or 10 steps/mm (roughly 1/10th what FDM printers get).
Their membrane tech is pretty big if they let other people use it, because I hear that the problem with those other goo-based printers, the limiting factor is how each layer gets scraped off the build glass which can break the part.
Looks cool as heck though.
