The UV (300-410nm) resins are easily made clear in the visible spectrum.
Mercury lamps in off the shelf DLP projectors output in this range but
the color wheels and optical coatings on the lenses reduce it's efficiency.

Even my el-cheaper printers interact with my PC
I suspect that that is on their long-term roadmap.
But, right now, they are trying to re-invent the wheel. After 6 years of
development, they are now only about 30 years behind the industry
standards.
Rep-rap has been developed from the Maker movement. The one major knock I
have against that is
Loading an SD card works because it
is pretty bullet-proof and easy to manage as is just pressing a button.
Also, most of them are running from laptops, so they don't have a
parallel port or PCI slots.

IANAL,
But as far as I know, the only part of a patent that *really* matters is
the claims. So even though the description seems obvious, the claims
might say something like: where the insulator is made of pure
unobtainium. That might be non-obvious.
