With most laser machines the answer is no, however it is possible with a UV laser.
UV laser systems are perfect for marking delicate materials. Commonly used on glass and crystal, UV lasers use what is known as “cold processing”, this is where the laser uses high energy photons on the ultraviolet spectrum to break the chemical bonds in the material through a cold reaction, therefore making a mark on the material.
As this process generates no heat it is perfect for delicate materials which would usually sustain thermal damage from fiber and CO2 lasers. This is why the use of 3D printing onyx® and marking it with a UV laser system is the perfect combination in modern day smart manufacturing.
3D printing allows for the creation of unique highly detailed parts, however it is not possible to create parts with intricate markings with the 3D printer alone, this is where a UV laser system comes in. Being able to mark Onyx® with high precision, allowing for QR codes, part numbers and other critical markings to be added to the material without damaging the part in any way.
