One of the advantages of owning a laser engraver is the wide array of materials that can be engraved. Traditionally, laser engravers were too expensive for the man in the street but the introduction of inexpensive ones has now made it possible for anyone to set up a laser engraving business. All you have to do is buy a good laser engraver, choose the best material and you are good to go!
But which are the best materials for laser engraving? A laser engraver can be used to engrave, laser-cut, and mark several materials including rubber, leather, plastics, textiles, wood, and metals.
However, if you are using a fiber laser engraver, then you may want to avoid working with organic materials like wood and leather because even though they are not transparent to the human eye, they appear transparent to the 1062nm wavelength of the fiber laser beam. It is, therefore, a good idea to ask the manufacturer of your laser for the list of permitted and disallowed materials before you start using it.
