Default Laser or plasma

While recently in Mexico, there is a glut of metal sculpture, not a piece
of which I saw bought. Schools of fishes, large sailfish, small sailfish,
three dimensional trees all cut out of a flat piece of metal, then pushed
out to achieve depth. I can see the cuts, and they are definitely either
plasma or laser. Some of them are very thin. How is it possible to
differentiate between laser cut goods and plasma cut? Just how thin can a
plasma cut be?

I've seen the same stuff in south FL. It looks to be done with an
inexpensive CNC plasma.

There is a HUGE range in plasma cutter quality. Goes from looking like a
cheap Oxy torch all the way to almost laser with the fine cut consumable
oxygen units.

"The Kid's" full time job is lead man on a bank of laser cutting machines.
The new unit cost $300K ($600K with the accessories) and it cuts to 1 thou
tolerance with a mirror smooth edge. They put a lot of stuff on that laser
that used to be CNC milled.
