Re: CNC Painting

I have always wanted to put an airbrush on my router and spray
artistic designs on t-shirts. I thought that the z height could be
varied slightly to get different line widths and density. I still mean
to try it some day. I would just do it as a hobby, but I wonder if
there may be a market for a mall kiosk where customers could watch
there own shirts get sprayed by a "robot" artist. A small silkscreen
dryer could cure them in a few minutes. The designs could even be
customized with their names etc. Just thinking out loud. Actually, it
is this very concept that got me started in cnc 5 years ago.
