Turn a small marble stone into a beautiful charm for any type of event.

Preparation

Required material:

Small marble stones (we used a marble mosaic tile and removed them from the mat)

Machine used:

Speedy 360, 100 Watt
1.5" lens
Vacuum table

For this sample you can use any laser machine from the Speedy laser engraver series.

Tip:

Use the 1.5" lens if you want to engrave fine details as shown in our graphic

Step by Step

Step 1: Import design

Create your own file or import our template, then send the job to the laser machine using the settings below:

Print settings

Process mode	Resolution	Cut line
Standard	1000 dpi	none

Halftone	Others
Color	-

Tip:

Since we are engraving in great detail, using the highest resolution possible is recommended (1000 dpi).

Step 2: Engraving the marble

The first step is the wash the dust off the stone by running it under water. Let the stone dry off, then place it in the laser machine and focus on the surface. If the stone is rounded, focus on the average value of the engraving area. Enter the material parameter settings. The parameters can vary depending on laser machine and available laser power.

Laser parameters engraving:

Color	Process	Power (%)	Speed (%)	ppi/Hz
black	Engrave CO₂	50	20	1000

Passes	Air Assist	Z-Offset	Advanced
1	on	- 0.5 mm	-

Info:

We used a negative offset value. Thereby the surface is exposed to more laser power and the engraving shows more contrast.

Step 3: Cleaning

Clean the stone with a damp cloth, we do not recommend putting it under running water as it will wash off the engraving dust which gives contrast to the engraving and shows better.
