Medical Devices

Precision is life-saving in the medical world. From surgical instruments to implants, every device needs proper labeling for compliance. Laser engraving is the go-to method for durable, corrosion-resistant markings.

In fact, regulatory bodies like the FDA often require such permanent markings.

Medical Instruments

Laser engraving is critical in the medical field for marking surgical instruments and devices. This includes engraving serial numbers, barcodes, and brand logos, which are vital for traceability and regulatory compliance. The non-contact nature of laser engraving preserves the integrity of the instruments while providing clear and permanent markings.

What About Aerospace, Defense, and Automotive?

Aerospace and Defense

High precision is a must in these industries. Laser engraving ensures traceability and reliability for aircraft components and military equipment.
For example, critical parts of an aircraft often bear engraved serial numbers that endure extreme conditions.

In the aerospace industry, laser engraving is used to mark critical components with identification numbers or specifications. The high precision of laser technology ensures that these markings meet strict industry standards without compromising the structural integrity of the parts.

Automotive Industry

VIN codes, dashboard components, and gear labels—all these rely on laser engraving. Its speed and precision make it irreplaceable in high-volume automotive manufacturing.

Aerospace companies avoid using laser engraving for components due to high costs.False

Aerospace industries rely on laser engraving for precision and durability in marking components, despite its cost-effectiveness.


Stainless steel is a popular choice for laser engraving due to its corrosion resistance.True

Stainless steel’s strength and resistance to corrosion make it a common material for laser engraving.

Parameter Settings for Laser Engraving on Stainless Steel

Parameter Recommended Range Details and Tips
Laser Power 80–180W Adjust based on the thickness and type of stainless steel. Thicker materials may require higher power.
Engraving Speed 0–1000 mm/s Start with a lower speed and adjust as needed. Higher speeds may reduce detail, while slower speeds can affect efficiency.
Frequency ~100 kHz Higher frequency reduces engraving depth, making it suitable for surface detailing.
Focus Position Offset by 2–3 mm Slightly defocusing can improve engraving results. Test for optimal adjustment.
Power Ratio Lower for black engraving Reduce power ratio and increase speed when engraving black for better contrast and clarity.
Filling Method Adjust based on font size For smaller fonts, increase the density to improve visibility.
Corner Speed Adjust for precision Fine-tune corner speed and acceleration to balance between engraving precision and efficiency.

Additional Tips

  • Testing and Optimization: It’s important to perform multiple trials with different parameter combinations to identify the most suitable settings for your specific project.
  • Engraving Depth: Shallower engraving is often sufficient for surface marking, while deeper engraving may require adjustments in power and speed.
  • Material Variations: Different stainless steel grades may react differently, so adjustments may be necessary.

By following these recommendations and experimenting with parameter settings, you can achieve high-quality engraving results on stainless steel.
