Etching or engraving for diverse surfaces
Laser engraving process involves the user of laser for creation of detailed designs for etching or
engraving in material surface of distinct objects. Engraved images or designers may include
extremely high quality and finely designed delicate features while some may include mere
marking designs for identification or other purpose. The application includes industrial usage for
numerous sectors like keepsake engraving, medicine and engineering field, etc. Engraved
photographs on hard and durable surfaces like smooth tiles, etc are becoming well sought after in
the market giving a rise to the market for laser engraving.
Since laser offers higher versatility, a broad spectrum of materials and metals can be used for the
process and even though at the beginning of laser engraving research and tests, the metals were
fairly incompatible but now it is vastly used on novel metal alloys and other laserable materials.
Laser engraving machine and process for Wood and Paper
Burning designs through laser into wooden objects is touted among the earliest uses of this
process. Since wood doesn't take too long for burning and offers a compatible surface, it only
requires low-wattage lasers. Hardwoods like oak work quite amazingly with laser processes
however, softer woods may result in inconsistent depths in the design and have been claimed to
cause flame or ignition due to the etching process. Low wattage laser works best on wood and
paper and fiberboard functions great in context of papers but newsprint or linty paper could lead
to burning.
Plastics
Acrylic is vastly used for laser etching as it keeps the etched design together and results in a
splendid finished output. Bakelite and other hard plastics also work best with this laser etching
process. But Styrene and other similar softer plastics don't work too well with it as they tend to
melt during the process so the engraving ends up having a deformed appearance instead of the
expected result.
Like metals, numerous special plastics that are laserable are designed specifically for the purpose
of laser etching. Silicates are frequently used to reduce the heat during te process and prevent
melting of excess material. Vinyl and silicones are not compatible and don't function at all when
used for engraving through laser.
Laser engraving machine or Metals
Certain Standard metals need a predefined, shorter-wavelength for the treatment which is why
the machine also needs to be specifically designed to accommodate these materials or metals
needs. So, using all types of machines will not yield positive results. The machine designed for
coated metals also utilizes a distinct functional aspect and results in better results after it
vaporizes the coating for the metal under it such as anodized aluminum. Patented technologies
by different manufacturers are now used to make engraving machines better suited to metals.
Stone and glass are considered fairly hard to engrave well through use of lasers and usual work
well when treated through conventional or other engraving techniques. Nevertheless, a special or
a combination of distinct engraving technique can be used to develop beautiful patterns since
stone and glass produce some of the best results and work well in terms of durability.
