What kinds of stones can be engraved with the laser?
Laser engraving on stone is particularly suitable for polished, ideally dark natural stones such as granite, marble, or basalt. The more homogeneous and fine-grained the stone, the better the results of the stone engraving will be. However, even pebbles can be processed well with the laser due to the smooth surface. Another ideal candidate: White marble – the laser engraver can produce a homogeneously white stone engraving.
Can stones be cut with the laser as well?
Laser cutting of stones is not possible.
How to get a stronger contrast during laser engraving on stone?
In order to achieve a stronger contrast, you can fill the engraving with synthetic resin or lacquer. Especially in the case of polished stones, the lacquer or the resin adheres particularly well to the engraved (and thus roughened) surface.
What must be taken into account when engraving photos?
As stones have an uneven surface, they are best suited for coarsely rasterized images (250–333 dpi). Very fine and detailed images may be difficult under certain circumstances, but this depends very much on the structure of the stone.
