SÌ, you can engrave metal with a fiber laser. Infatti, fiber lasers are one of the most effective tools for engraving a wide variety of metals, compreso l'acciaio inossidabile, alluminio, ottone, rame, e altro ancora. The focused beam of a fiber laser creates detailed, high-contrast marks that are both durable and resistant to wear. Fiber lasers can perform different types of metal engraving, such as annealing, acquaforte, and deep engraving, making them versatile tools for various applications, from industrial marking to personalized items.

2. What Can a Fiber Laser Not Engrave?

While fiber lasers are highly effective for metal and some plastics, they have limitations when it comes to certain materials:

• Transparent Materials: Fiber lasers struggle to engrave clear materials like glass or acrylic because the laser light passes through them without being absorbed.
• Materiali organici: Fiber lasers are not well-suited for engraving organic materials like wood, pelle, or paper. CO2 lasers are better for these types of materials.
• Highly Reflective Metals: Although fiber lasers can engrave most metals, extremely reflective metals like silver and gold might require special settings or surface treatment to avoid reflecting the laser beam and damaging the equipment.

3. What Are the Limitations of Laser Engraving?

Incisione laser, while powerful and precise, does come with some limitations:

• Compatibilità dei materiali: Not all materials can be engraved effectively. Per esempio, certain plastics may emit harmful fumes, and transparent or highly reflective materials pose challenges.
• Depth Limitations: Achieving significant engraving depth can be time-consuming, and some materials may not allow for deep engraving without compromising structural integrity.
• Size Restrictions: The work area of the laser machine limits the size of the objects you can engrave. Larger items may need to be engraved in sections or require specialized equipment.
• Surface Preparation: Certain materials might need pre-treatment (per esempio., applying a coating or paint) to achieve the desired engraving result, which adds extra steps to the process.

4. Will a Fiber Laser Cut Metal?
