Laser cutting & engraving of metal

Choosing the right metal cutting laser is a critical factor for professionals involved in industrial applications, construction, marking, and metal component production. Unlike mechanical machining, lasers offer high precision, speed, and repeatability without mechanical stress on the material.

On this page, you will find a detailed guide on which laser machine is suitable for cutting and engraving metal, which materials are supported, what to consider before purchasing, and how to choose a solution based on your actual production needs.

Metal cutting laser – which technology is suitable?

For cutting and engraving metal, the most suitable and modern solution is the Fiber Laser. Fiber lasers have high energy efficiency, long life, and excellent performance on metal materials such as stainless steel (inox), aluminum, steel, and galvanized steel. long life, and excellent performance on metal materials, such as stainless steel (inox), aluminum, steel, and galvanized steel. The laser beam is very thin and has a high energy density, which allows for high cutting speeds and high precision.

Unlike CO₂ lasers, fiber lasers are specifically designed for metal applications, offering faster cutting, less maintenance, and consistent quality in continuous production. Fiber lasers are also ideal for cutting thin materials, such as sheet metal, because they can cut through materials with a thickness of 0.01 mm. Fiber lasers are also ideal for cutting thin materials, such as sheet metal, because they can cut through materials with a thickness of 0.01 mm.

What materials can be cut and engraved with a fiber laser?

• Stainless steel (Inox)
• Aluminum
• Black and structural steel
• Galvanized sheet metal
• Brass and copper (depending on power)

What to consider before buying a metal laser

• Laser power (Watt): Determines the thickness and cutting speed.
• Application type: Sheet cutting, engraving, serial numbers or marking.
• Work surface: Depending on the sheets or pieces you are working with.
• Movement precision: Servo motors and sturdy frame.
• Cooling system: Constant temperature for continuous operation.
• Safety: Enclosed chamber and certifications.
• Service & spare parts: Important for professional production.

Metal engraving laser – when is it needed?

Fiber laser metal engraving is widely used for industrial marking, serial numbers, QR codes, logos, machine plates, and regulatory compliance (CE marking). The result is permanent, indelible, and high-contrast.

Laser cutting & engraving applications for metal

• Metal structures and components
• Industrial signage and signs
• Electrical panels and boxes
• Spare parts and custom accessories
• Jewelry and detailed metal objects

How many watts does a laser for metal need?

The required power depends on the thickness and type of metal. For thin sheets and engraving, lower power may be sufficient, while cutting thicker materials requires higher wattage. Choosing the right power ensures quality, speed, and lower operating costs.

Frequently Asked Questions (FAQ)

Can I cut and engrave with the same machine?

Yes. Many fiber lasers support both cutting and engraving, depending on the power setting and equipment.

Does fiber laser require frequent maintenance?

No. Fiber lasers have low maintenance requirements compared to older technologies.

Is it safe to use lasers on metal?

With the right enclosed chamber, safety systems, and training, fiber lasers are safe and reliable to use.
