UV resin printers have been a popular research area in the DIY 3D printing community for the last year or two. There are a few more too. Most are based on DLP projectors with some hackery to remove the color filters (e.g. carefully snap off a hundred little pieces of glass from a rotating wheel) as I understand it, which makes them expensive and fragile for a individual. This is a situation where volume assembly of a complete device makes more sense than garage experimentation, so Formlabs' work looks promising to me.
