I do not own a fiber laser, but I have been using Cermark for years.

In your opinion......for use with stainless steel in a clean room, what would be better.....marking a part with a fiber laser or using cermark? I remember Ferro used to tout that Cermark was used by NASA and for marking medical equipment. I can't remember if it is food safe.

I think that my CO2 laser is getting more and more obsolete, so I'm just wondering what applications are left that make it stand out.
