I modified several laser printers to deposit toner directly on
copperclad. It worked well but was a bit cumbersome at times and I had to
drag out this big printer every time I wanted to use it. For me, using
either pre sensitized boards or keeping a supply of boards I have
previously laminated photosensitive film on seems like it would be very
quick without the intermediate step of making transparencies.
Each to his own, but it's fun experimenting. Yesterday I was able to
successfully remove the backlight from an Ipad screen I bought used. Will
post when I have some results.

I don't see the point of that.
UV lamps are cheap adn so are printer transparencies.
My cheap inkjet can do 4800x2400DPI and good photoresist is
cheap.
Compared to that, 3D printer is very crappy option.
I was thinking more along the lines of reworking something like
Epson's
cheap A3+ Workforce WF-77xx printer or multifunction into printing
directly on PCB panel.
For me, that would be a meaningful change.
Pritner is GREAT in general, cheap and above all, great for exactly
this
purpose.
