When processing thicker materials, a higher laser power is crucial for achieving a good quality result. As a rule of thumb for acrylic for example, we recommend 10 watts per milimeter.
A comparison of the laser cutting time for different sheet thicknesses of acrylic between 200 and 400 watts is shown in the graphic.
In addition to acrylic, other plastics can be processed by laser, such as polycarbonate or SAN. These require high powers of 200 or 400 watts in order to be able to cut them cleanly even with a comparatively low thickness of 2 and 3 mm.
