WHAT IS LASER ENGRAVING?
Laser engraving is used to give products an individual design or a personal touch. A
sports trophy engraved with the name of the winner, ballpoint pens engraved with the
company logo or a component that is marked with serial number and batch number - these
are typical applications for laser engraving. The big advantage: With a laser, you can
engrave virtually any design on different materials. On this page we explain how laser
engraving works.
Laser engraving is as simple as printing. First, create the layout of the engraving in
your usual graphics program (CorelDraw, Photoshop, AutoCAD, Illustrator, InkScape,
etc.). Then use the printer driver to send the graphic to the laser. At the push of a
button, your selected material is laser engraved or laser cut with the stored settings.
If required, advanced settings can be set in the provided JobControl® laser software.
Process types stored in the printer driver make everyday work much easier by
automatically optimizing graphically required
Laser Engraving (or Laser Etching) is a Subtractive Manufacturing method, that uses a
laser beam to change the surface of an object.
This process is mostly used to create images on the material, that may be seen at eye
level. To do so, the laser creates high heat that will vaporize the matter, thus
exposing cavities that will form the final image. It is using the laser for marking the
surface of an item.
What is possible to do with laser engraving?
It can be used on almost any kind of metal, plastic, wood, leather or glass surface. Youcan get a lot of different engraved materials . Furthermore, it is more effective than
traditional engraving for small objects, such as jewelry. There are also smaller chances
to damage or deform the material. It can be used for many different applications, such
as medical devices , fine art and so on.
It can be used for industrial applications , but it is also possible to get a DIY laser
engraver machine , for example with a CO2 laser system . You just have to connect your
CO2 laser engraving machine on the USB port of your computer and it will work like a
printer.

Laser engraving technically explained
During the process of laser engraving, the laser beam impinges on the material, exposing
it to a great deal of heat. Depending on the exposure time, the color changes and
creates a contrast, or the material evaporates or burns. The resulting laser engraving
is permanent and very resistant to abrasion.

Laser Engraving: how does it works?
This method is quick, as the material is removed with each pulse of the laser. The depthof the marks is controlled by the number of times the laser beam is passing on the
material.
There are different types of laser engraving machines :
First ones are engraver machines where the workpiece stay stable, only the laser moves
(or inversely). Other machines dedicated to cylindrical workpieces. The last
possibilities are laser engraving machines where the laser and the workpiece are both
immobile but galvo mirrors are moving the laser beam on the surface to engrave.
After reviewing hundreds of laser engraving machines in terms of quality, speed, efficiency and above all cost, the best I could find is the following with all its advantages and specifications
