4.6 Instructions for Specific Materials
The following instructions are suggestions to help speed safe work with a range of materials. The
user should research the specific safety and engraving requirements of their specific material to
avoid the risk of fire, hazardous dust, corrosive and poisonous fumes, and other potential problems.
Once the product is known to be safe or appropriate protective equipment has been set up, it can
be helpful to engrave a test matrix of small boxes produced at various speed and power settings
to discover the ideal settings for your design. Alternatively, start with low power and fast speed
settings and rerun your design as many times as needed, using progressively greater laser intensity.
4.6.1 Ceramics
When engraving on ceramics, generally use moderate to high power. Using more loops rather than
higher power and lower speed can help avoid cracking the material during work. Be mindful of the
health risk posed by dust generated from ceramic engraving, especially for repetitive industrial
applications. Depending on the material and the amount of work, a fan or even full ventilation
system may be required to address the problem. Similarly, operators and others in the work area
may need to use breathing PPE such as masks and respirators.
4.6.2 Glass
When engraving glass, generally use high power and low speed. As with ceramics, it can be helpful
to run more loops at lower settings to avoid cracks. Care must be taken when engraving fiberglass
and carbon fiber to avoid combinations of settings that produce a laser intensity great enough to
damage the structural integrity of its component fibers, producing blurry marking. PPE should be
worn to avoid exposure of the eyes, nose, mouth, and skin to the dust produced by working with
either material, especially for repetitive industrial applications. Clothing worn while working with
fiberglass should be washed separately afterwards.
