Laser Marking Meaning

Laser engraving or laser etching is a subtractive manufacturing method that uses a laser beam to change the surface of an object.

Laser marking meaning.

A fast and clean technology laser marking is rapidly replacing older marking. Laser marking works by using a focused beam of light to mark the surface of a material. To achieve a good result this should be the same or a multiple of the dpi selected in the print setting. A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation the term laser originated as an acronym for light amplification by stimulated emission of radiation.

Laser engraving and laser marking is the practice of using lasers to engrave or mark an object. Laser marking also known as laser engraving or laser etching is a marking method which utilizes laser light to mark materials using a fine spot diameter ranging from 0 002 to 0 01 the laser marks with short pulses 30 nanoseconds providing precise control and negligible heat input to the part. Laser marking on the other hand is a broader category of methods to leave marks on an object which also includes color change due to chemical molecular alteration charring foaming melting ablation and more the technique does not involve the use of inks nor does it involve tool bits which contact the engraving. The ppi parameter pulses per inch determines how many laser pulses per inch are used for the engraving.

Maiman at hughes research laboratories based on theoretical work by charles hard townes and arthur. This process is mostly used to create images on the material that may be seen at eye level. Laser marking is what happens when the beam interacts with the surface of a material slightly altering its properties or appearance. The mark settings object is used to change the laser settings within the marking sequence.

This concentrated beam targets only a specified area allowing the laser marking machine to create precise high quality high contrast marks that. To do so the laser creates high heat that will vaporize the matter thus exposing cavities that will form the final image. When the beam interacts with the material s surface it alters the material s properties and appearance. The technique does not involve the use of inks nor does it involve tool bits which contact the engraving surface and wear out.

Ppi and hz parameters. The first laser was built in 1960 by theodore h. The laser marking process. It is achieved by moving a low powered beam slowly across the material using a method called discoloration which creates high contrast marks without disrupting the material.

Laser engraving is the practice of using lasers to engrave an object.
