FAQ: Fiber Laser Marking Machines

Q1: What materials can a fiber laser marking machine work on?

A: Fiber laser marking machines are best suited for metals such as stainless steel, aluminum, brass, copper, gold, silver, titanium, and hard plastics like ABS and polycarbonate. They can also mark some ceramics and coated materials. However, they are not ideal for wood, glass, or transparent plastics—CO₂ lasers are better suited for those.

Q2: How does fiber laser marking work?

A: Fiber laser marking uses a focused beam of light from a fiber laser source to alter the surface of a material. The process involves localized heating, which causes oxidation or vaporization, creating a permanent mark. The laser beam is controlled by a galvanometer (mirror system) to move rapidly and accurately across the material surface.

Q3: What are the advantages of fiber laser marking over traditional methods?

A: Key benefits include:

• High precision and clarity, even on small components

• Fast marking speed, improving productivity

• Non-contact process, which means no physical wear and tear

• Eco-friendly, with no need for ink or chemicals

• Low operating cost, thanks to long laser life and no consumables

Q4: How do I choose the right wattage?

A: Wattage depends on the material and the depth of the mark:

• 20W–30W: Light marking, barcodes, serial numbers on metal/plastic

• 50W–60W: Deeper engraving, faster cycles

• 100W+: Heavy-duty applications, high-speed deep engraving on tough metals

Q5: Can it be used for color marking?

A: Yes, but it depends on the material and machine configuration. Some fiber lasers can produce color markings on stainless steel and titanium through controlled heat oxidation. However, color marking is more sensitive and slower compared to standard marking.

Q6: What maintenance is required?

A: Very little. Since fiber lasers are solid-state and air-cooled, there’s no need for regular part replacement or liquid cooling systems. Basic dusting and checking for lens cleanliness are generally sufficient.

Q7: Is training required to operate the machine?

A: Basic training is recommended, especially on using the software (like EzCAD) and understanding safety precautions. Most suppliers provide online or in-person training upon purchase.

Q8: Is fiber laser marking safe?

A: Yes, but proper safety measures are essential:

• Use protective eyewear (lasers are Class 4 devices)

• Shielded enclosures and interlocks are recommended

• Proper ventilation in the work area to remove fumes
