What Power Level Is Recommended for High-Quality Laser Cut Mylar?

As a general guideline, for thin Mylar sheets around 0.1 mm (100 micrometers) thick, a low to medium-power laser can be used, typically in the range of 10 to 40 watts. Thicker Mylar sheets, such as those around 0.25 mm (250 micrometers) or more, may require higher power lasers in the range of 40 to 100 watts or more.
