Hi guys!

I am working on a project to build a SLS printer. While searching for a galvo setup for my machine, most of them were meant for laser projectors(stage lighting). Can we use these galvos for SLS? I plan on using a 40W CO2 laser for the sintering. Can anyone please help me in this matter? Most of the galvos in the net are too expensive, it would be really helpful if anyone could me some links where I can find some inexpensive galvo setup.
