15 Facts About Laser engraving

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

Simply speaking, laser engraving is the process of selectively removing microscopic layers of material, thus creating visible marks on the treated surface.

Laser engraving engravers using this technology can work in either raster or vector mode.

Laser engraving can remove material very efficiently because the laser beam can be designed to deliver energy to the surface in a manner which converts a high percentage of the light energy into heat.

Good example of where laser engraving technology has been adopted into the industry norm is the production line.

At the point of engraving, the laser beam is focused through a lens at the engraving surface, allowing very precise and intricate patterns to be traced out.

Vector Laser engraving follows the line and curve of the pattern to be engraved, much like a pen-based plotter draws by constructing line segments from a description of the outlines of a pattern.

Paper masking tape is sometimes used as a pre-Laser engraving overcoat on finished and resiny woods so that cleanup is a matter of picking the tape off and out of the unengraved areas, which is easier than removing the sticky and smoky surround "halos" .

Laser engraving can cut into both flat and curved surfaces such as the surfaces on jewelry.

Since approximately the year 2000 the direct anilox laser engraving process has been dominated by the use of fibre lasers which provide the high powers of the carbon dioxide lasers together with the finely focusable beam of the YAG lasers.

Sub-surface laser engraving is the process of engraving an image in a transparent solid material by focusing a laser below the surface to create small fractures.
