Iv got a customer that has a MAZAK Laser and it will cut shapes out of pipe and at its lowest power setting it will ingrave (not cut all the way through) but considering the cost of the machine and the software for it i dont have 1,000,000 laying round to buy one. you can see a little bit about the machine they have here
Laser Cutting Services now personaly after seeing what it cost to fix that thing when it brakes and only has a 6 month warrenty i would never own one of theres. dont get me wrong its a nice machine when its running but you could buy allot of plasma tables and all kinds of other toys for what that thing cost.
