[0002] As the name suggests, a laser engraver is an advanced device that uses lasers to engrave materials. Laser engravers differ from mechanical engravers and other traditional manual engraving methods. Mechanical engravers use mechanical means, such as diamond, to engrave objects with extremely hard materials.
