Engraving with a laser
is actually a simple process. A laser is merely a tool. Laser can engrave most
materials today. The most popular materials in the engraving fields are coated
metals, wood, acrylic, glass, leather, marble, plastic, and a host of synthetic
materials made specifically for lasers. Although it's confusing sometimes laser
marking is referred to as laser etching. Unlike conventional
etching, laser etching simply needs no masks or chemicals.
It was back in the early
1960's when scientists first discovered, that they could create a light source,
focus the energy and have a tool powerful enough to affect certain materials.
Laser marking is the favored marking method when permanency or aesthetics are
needed. It didn't take very long for the engraving industry to notice lasers
and soon lasers were being used for a wide variety of industrial applications including
welding, heat-treating, etching and engraving.
If you think of a laser
as a light source similar to a light bulb you'll know that a light bulb will
emit energy out all around it. And the term laser etching is basically just
another name for laser engraving.
The ability to laser cut
complex profiles can eliminate the need for additional operations, making laser
cutting very economical. And laser cutting offers a superior cut-edge quality
with parallel sides and with no burrs. Laser cutting adds high precision,
reduced contamination or warping, and a good quality finish to industrial
cutting applications.
The laser metal cutting option can be added to some of the
laser cutting machines. A laser works very well for the cutting of acrylic
(Plexiglas), PETG, thin poly carbonates (Mylar), styrene expanded PVC (Sintra),
wood, paper and fabric.
