Direct Part Fiber Laser Marking.

This has given rise to the practice of direct part marking. It is the process of permanently marking parts to enable users to track them throughout their life cycle. The most common marks are bar codes and data matrix codes, which are cut, engraved or stamped onto the parts. Laser marking technology is a popular method for marking parts today.

QR Codes

A two-dimensional matrix code, consists of black and white cells set up in a square or oblong shape. These symbols represent bits of data, with the black lines indicating a “1” and the white spaces indicating a “0” – the two digits used in data storage. The matrix can store up to 2,335 characters, including both letters and numbers, which are encoded onto the bits.


Barcodes come in one- and two-dimensional options. The linear or one dimensional barcode represents data through the varied width and spacing of parallel lines. Two-dimensional barcodes use rectangles, dots, hexagons and other geometric patterns and symbols that are machine readable using computers, smart phones and barcode scanners. They are used in direct part marking mainly for the purpose of tracking data on manufactured components. The marks are laser engraved on the components for purposes such as:

  • Lowering manufacturing costs through loss control
  • Quality assurance
  • Compliance with government regulations and industry standards

Benefits of Using Laser Engraving

  • It’s not only permanent, it’s also very difficult to intentionally remove. This makes it ideal for identifying components that have a high value and need to be protected.
  • Barcodes are easy to read using a range of systems, including mobile applications
  • Laser engraving of marks enables very small sizes to be used with a high level of fidelity.
