What is laser engraving
Co² Laser
The type of laser that I use is an industrial grade CO2 laser.
A CO2 laser emits invisible infrared light at a wavelength of 10,600 nm. When focussed, the beam of light is able to precisely cut, engrave or etch a wide range materials.
What can a laser do?
Cutting
The laser can cut a wide range of material: wood, acrylics, leather, vinyl-free fabric, paper and cardstock to name a few.
Limitations:
A Co2 laser cannot cut through metal, stone, glass or vinyl. Glass will shatter under the sudden temperature difference required to cut. Vinyl based products emits hydrochloric acid when vaporised by the laser.
Engraving
Engraving involved removing material to a precise dept without cutting all the way through. The laser can remove a very precise amount of material.
Everything that can be cut can be engraved.
Etching
Etching refers to slightly marking the material, or removing coating over a surface that can’t be engraved. Glass, including mirrors can also be etched. Same goes for a lot of powder coated metals. Most stone based material can be etched as well. Everything that can be cut or engraved can be etched.
Common materials
Wood
Wood is a fantastic medium to use with a laser. It can be cut with an unmatched precision as well as engraved.
Acrylic (Plexiglass)
Laser can make perfect cuts, which allow for incredibly clean end results and stronger bond when using solvent to glue pieces together. Acrylic can also be engraved with different effects. Great for illuminated signs or night lights.
Slate and other stones
Slate and stones can make for extremely durable products. Etching them with a laser gives wonderful results.
