FAQs: All You Need to Know About Metal Laser Cutters
❓ What is the best laser for cutting metal?
Fiber lasers are the best for cutting a wide range of metals due to their speed, energy efficiency, and ability to cut reflective materials like aluminum and copper.
❓ How thick of metal can laser cutters cut?
It depends on the laser wattage. For example, a 6kW fiber laser can cut up to 25mm stainless steel and 30mm mild steel.
❓ Do laser cutters require ventilation?
Yes. Fumes and particles from cutting need to be extracted using fume extractors or ventilation systems, especially when cutting stainless steel or zinc-coated sheets.
❓ What’s the average cost of a metal laser cutter?
Anywhere from $15,000 to over $500,000, depending on wattage, size, brand, and features like auto-loaders and real-time monitoring.
❓ Is training required to operate one?
Absolutely. Operators need to understand CAD file prep, material settings, safety protocols, and machine maintenance.
