It's worth mentioning this topic alongside the OpenManufacturing google group post on photopolymer printers: https://groups.google.com/forum/?fromgroups#!topic/openmanufacturing/bbQD-Gc00H0 and more loosely, the DVD burner used for graphene supercaps: https://groups.google.com/forum/?fromgroups#!topic/openmanufacturing/MWz-ONRVBVE (cross-posting is confusing as it is; perhaps meta tags can be visualized on some metagroup GUI)

Looks like a Blue Ray drive could be converted into a scanning UV photopolymer 3D printer with very high resolution. Maybe use rotary scan by spinning either the build vat and stage, or the drive itself (SATA would make the electrical slipring less ugly)
from Lemon Curry project, a UV DLP project, http://code.google.com/p/lemoncurry/wiki/main :
"Visible Light Cured
405nm and above photopolymers are sensitive to light within the visible spectrum and should be handled away from sunlight or bright lights.
405nm is used in the LED lasers found in Blue Ray drives.
470nm Blue Led's are available in a wide range of power levels and beam angles. "
