8. Instructions for Specific Materials
When engraving a new material, it can be helpful to engrave a test matrix of small boxes
produced with various speed, power, and frequency settings to home in on the exact effect
that you are looking for. To speed the process, here are some general guidelines for
commonly engraved materials. Again, however, these are only guidelines for your
convenience and it is the responsibility of the user to consult material safety data sheets and
other sources to ensure the safety of working with various materials and setups. Some of the
materials listed will require additional workspace and personal protective equipment in
addition to this engraver:
Metals
When engraving metals, generally use high power, a low frequency, and low to medium
speed settings. To avoid using your marker at greater than 80% power for extended periods,
you can also get similar effects by reducing the power somewhat while also increasing the
number of passes or decreasing the engraving speed. Be mindful that some metals will
produce conducting, reflective, and/or toxic dust. Softer metals naturally produce more dust
during engraving, while harder metals can require higher power settings that also produce
more dust. In addition to the risk to the user's skin and eyes, there may be enough dust
produced (especially for repetitive industrial applications) that a full ventilation system is
required to address the problem. Similarly, operators and others in the work area may need
to use breathing PPE such as masks and respirators.
Aluminum: Bare aluminum requires a somewhat higher frequency than other metals and will
never produce a strong black mark similar to those created by engraving steel. When darker
marking is required, consider employing anodization or producing a deep engraving that can
be darkened by using black epoxy or other filler. Anodized aluminum requires a little more
speed but a very low frequency.
Powder Coated Metals: Metals with a powder coating usually require a very high frequency
and, for best results, at least 3 passes to remove the coating and polish the bare lower layer.
Precious Metals: Gold and similarly soft metals should be engraved with less power but a
moderate speed. Silver and other semidurable metals are best engraved at a slightly higher
power and slightly slower speed, but still not at the same power and speed as as steel or
aluminum.
Plastics
When engraving plastics, generally use low power and high speed settings. Marking and
engraving with too much power or at too low a speed can concentrate too much energy at
the point of contact, causing the plastic to melt. Among other problems, this may produce,
poor engraving quality, noxious fumes and even fires.
