Methods for Wood, Canvas, Mirror, Slate and Tile

Precise focus of the laser is critical. Every laser is different – practice makes perfect.

Wood

Wood is one of the more popular options for engraving because it’s easy to find and relatively low cost. However, engraving wood can be a frustrating endeavor if you aren’t aware of some key considerations.

Not all types of wood engrave well, and even the same wood may not engrave the same due to differences in moisture or resin content. So let’s look at some considerations when selecting wood.

Resin Content

Higher resin content is found in softer woods, which are typically lighter colored, and the more resin, the darker the burn (engraved markings). Resin levels are affected by where and when the wood was cut. Alder, Maple and Cherry are premium options.

Streaking

Lines naturally present in some woods caused by mineral content. The streaks are visible after engraving and reduce the impact of the final result.

Shade

Lighter wood provides a stronger contrast to the engrave (burn) lines, allowing your work to stand out.

Good examples of wood for engraving include:

  • Alder (great for photos)
  • Cherry (great for photos)
  • Maple (great for photos)
  • Basswood
  • Plywood
  • MDF
  • HDF
  • Balsa

Tip: Mask a high contrast portion of a photo and run on different settings to find what works best for your laser.
