We have the Direct Imaging system here.  Gerber files are input into a standard PC, and it uses a wax printer to mask sheets of copper
clad polyamide.  These are etched , cut out, then aligned on a layer of ft4 material with glue between the layers, which is heated to
bond them.  Pins & tubes are inserted to join the layers together.  Drilling takes place at various stages.  They claim 5/5 resolution
is possible but I haven't tried anything that fine.  Soldermask is an optional stage.
