Materials for Laser Engraving
There are several materials used
for laser engraving; here is a description of them.
The following links will help better explain
the different types of materials used in and for laser engraving.
Wood Engraving
Softwoods tend to vaporize or ignite at less
consistent depths. Lowest power, quickest speed, and a blowing fan are
required for softwood.
Engraving Plastics is Popular
Special plastics for engraving have been developed
for signage, faceplates, and other items. These plastics incorporate
silicate and other materials that conduct heat away from the material
before it can become deformed. Outer laminates easily vaporize to expose
a different colored material underneath.
Metals and Coated Metals
Brass, copper, and stainless steel, the best
traditional engraving materials, are the worst materials for laser
engraving. The laser beam cannot penetrate these materials unless the
power is raised above 75 watts, and even then the results are poor, with
ripples and deformed edges.
Stone and Glass
Stone and glass do not vaporize easily.
Sandblasting or tools with diamond drills or wheels are often still
preferred for engraving these materials. |
