looks good for steel,
remember ; if you want your machine size to fit in a normal room and print in hours not weeks then you have to work in steel, not other metals, Irrespective of the amount of money you have got to spend on the laser and the size/ rating of its power source.
as
The larger the laser the longer its focal length so you can get very large machines.
Except steel most metals absorb only single digit percentage proportion of laser beam energy.
calculate it your self
