8-2 Sample Materials
DO NOT ENGRAVE OR CUT PVC (Polyvinylchloride) BASED MATERIALS. The fumes are
extremely toxic if you inhale them. The fumes are so caustic that it can chemically destroy the
metal parts of the laser system. Damage to the laser system from this type of abuse WILL NOT
be covered under warranty.
There are many variables that can affect the cutting and engraving process such as differences
in the thickness of the material, density of the material, composition of the material, and the
manufacturing processes used to make the material. Please use these settings as a guideline,
in most cases these settings should work out well, but sometimes may have to be adjusted to
produce desirable results.
In compiling these settings, all samples were run with the resolution set at 500 DPI(except were
otherwise noted). When using a lower resolution in order to achieve greater engraving speeds,
remember that the resolution will be reduced which in turn will reduce quality and depth. In
order to compensate for lower resolution settings, lower the speed and/or increase the power to
achieve the same depth. The opposite applies for higher resolution settings.
Below is a list of the various materials that were tested. The following pages will fully describe
the results of these tests and will offer helpful hints when choosing materials, setting
parameters, and using different techniques to provide the best laser cutting and engraving
results.
