A 150-watt or higher CO2 laser (700 used -8000)  is generally needed to cut metal, with higher wattages allowing for cutting thicker materials. For example, a 150-watt laser can cut up to 1.2mm thick metal, while a 400-watt laser can handle up to 3mm. Additionally, certain metal cutting technologies, like those developed by Kern Laser Systems, can enable CO2 lasers in the 100-650 watt range to cut metals like stainless steel, aluminum, and brass efficiently.

CNC plasma should be a more  practical solution.
Big issue is the cost of steel or aluminum.

Plasma with jigs goes a long ways.
