As a natural material please be aware that the tone of the wood grain can differ slightly from sheet to sheet. In some cases this can be quite variable. Tones vary from rich brown / reddish tones to more silvery / brown tones.
Both faces of walnut sheet are laser cut with protective paper backing applied to minimise burn marks and ensure a clean result. In some cases a subtle discolouration can occur around the surrounding area of the cut line if the backing has not adhered fully to the surface. These marks are usually unnoticeable but they can be easily sanded off with a fine grit wet and dry paper if required.
The average cutting kerf (how much the laser takes away) for Walnut is +/- 0.1mm. As a benchmark, we recommend that minimum cut widths be no smaller than the corresponding thickness of the material. For example, if cutting from 3mm walnut, it’s best not to allow any widths less than 3mm. We can go smaller (see cut width image above) but this can make your components quite fragile which might not be suitable for some applications. See more on cut widths and Kerf (how much the laser takes away.)
Laser cuts with a dark brown tinge edge.
For walnut our standard raster engraving is a shallow light surface scratching and has a dark brown appearance that is darker in tone than the walnut surface. The laser also subtly reveals the texture of the wood grain. As standard we engrave through the protective backing (applied for laser cutting) into the walnut surface. You will need to remove all the protective backing once you receive your job.
Please be aware that as a natural material, slight variation in the tone of the engraved finish can occur from sheet to sheet. Tone of wood, grain line and density and moisture content all have an impact on the engraving tone. Variation in tone can also be affected by power distribution if you have lots of pieces of artwork to engrave that vary in size.
If you would like your engraving to be deeper than our standard settings, you will need to specify this in your job request. Deeper engraving will be carried out through the protective backing in the same format as standard raster engraving. Be aware that the higher laser power and slower processing speeds required can cause more oils from the wood to be released.
