As with a milling machine, laser engraving allows us to make engravings in high relief.
In the photos of the two hairpieces, you can see how the logo and the reference are positive, that is, in high relief.
It is a matter of eliminating everything around the reference and the logo, except for these, of course, since that is what you want to reproduce.
The laser will move around the area, evaporating the material from the area surrounding the alphanumeric text (the reference) and the drawing (the logo).
Thus, this laser engraving in high relief will be achieved.
The height of the text or drawing (logo in this case) may vary as desired or due to the same limitations of the drawing to be engraved.
