How can you tell how strong a laser is
Laser cutting machines are able to cut metal with great precision. This is the main reason they are so popular. Plasma cutters can be cut with 2X greater accuracy than laser cutting machines. Plasma lasers can be used to cut metals with a precision of 0.1mm, or.004 inches. Laser cutters can cut metals at a precision of.05mm to.002 inches.
Some PVC-based acrylic releases toxic fumes when lasered. Therefore, it is better to check the chemical compositions of the materials you plan to engrave.
