Laser Engraving and the Six Most Common Materials
Once, prices for laser engravers were beyond most people’s budget, but there are now more affordable options on the market. Laser engravers are typically quite versatile in the variety of materials that they can engrave on or laser-cut. However, if you are using a fibre laser engraver, you may want to avoid many organic materials as they may appear transparent to the 1062nm wavelength of the fibre laser beam.
Six Common Materials for Engraving
1. Marble and Granite: are excellent for engraving photos due to their natural high contrast.
2. Stone and Brick: are great for engraving pieces that will go outdoors as they are tough-wearing against the elements.
3. Wood: is very commonly used but you will need to pay close attention to the different required parameters for each wood type.
4. Glass: produces stunning effects that tend to leave a frosted look but be mindful of possibly leaving a rough surface due to chipping caused by the laser.
5. Acrylic: is durable, lightweight and often comes in sheets, known as polymethyl methacrylate (PMMA) and is an excellent alternative to glass. Cast PMMA yields similar results to glass when engraved however extruded acrylic is more appropriate for laser cutting projects.
6. Metal: practically every metal can be engraved upon and it is the most commonly used material for laser engraving.
