Okay, Seats then: Oy, I envy you not, your volumes must be fun!
I am not sure how much those systems cost anymore. When I did this they were very spendy. Probably a lot cheaper now.
I do also recall that we had to think through carefully where we put them in the shop for part flow, lighting etc.
Once they were set it was a pain to move them and the projector to the lay up mold relationship was an important consideration.
Since the systems I played with were in their infacy then I would suggest getting as much freedom in that arena you can from the System Manufacturer. It caused us no end of grief.
Our application was Nacelle fixed and door panels that had a lot of very busy features, we were limited to the number of stations where we could use the laser projector. Our factory had multiple lay up rooms and our executives liked to shuffle things around which meant we broke down the original set up and moved it three or four times. It would take us the better part of a week to reset the system in its new location. (Again this is ancient history)
Changes to the actual projected ply locating lines did go pretty quick when we needed them.
Have bunches of fun!
Composites and Airplanes - what was I thinking?
There are gremlins in the autoclave!
