The more homogeneous and fine grained the stone the better the results of the stone engraving will be.
Laser engraving marble settings.
Of course there are many variables to consider for metal engraving.
Paint the area of the marble you are going to be engraving with a thin layer of white water based paint.
When laser engraved correctly it should produce a white or gray mark.
Also available is a laser cutter user guide.
The following are suggested laser cutter configuration settings for various materials.
The lasers wattage hardness of metal desired mark etch polish anneal and the required time contrast depth will have to be considered when deciding on the final settings.
Laser engraving on stone is particularly suitable for polished ideally dark natural stones such as granite marble or basalt.
Laser engraving settings when adjusting settings a good rule is to adjust either the power or the speed.
Starting with a dark color stone is the best way to achieve a high contrast without a color fill.
This week we are laser engraving marble coasters with quirky space icons on the speedy 400 flexx laser.
Also keep the power setting as low as possible.
Metals can be engraved at just about any settings.
This will help make pencil marks for outlining your engraving much easier on you since otherwise the pencil would just rub off the marble.
However even pebbles can be processed well with the laser due to the smooth surface.
We first put masking tape over the coasters engrave.
As a starting value use 100 power p with around 30 speed v for a laser engraver with 60 watts and then 100 power and around 15 speed for any machines with less than 60 watts.
Having less variables will help to find the optimum settings faster.
If you have other settings you d like to suggest please send an email to design help ncsu edu with the details.
Unlike the full power at low engraving speed that is required for wood or paper processing we recommend different settings for hard stone surfaces.
