Our supply: Stock material
Thickness: Available in 3mm and 6mm
Sheet sizes: 915×100mm only
A soft but strong wood with a subtle orangey tone. Spruce timber comes from coniferous evergreen trees and has a wide prominent grain. Grain Line runs horizontally with the longer length of the material.

Natural spruce timber is only available in a sheet size of 915mm x 100mm. The grain line runs horizontally with the longer length of the sheet. As a natural material, please be aware that tone of the wood and the width of the grainline can vary from sheet to sheet.
6mm spruce usually has a much stronger, more prominent grainline than 3mm thickness and looks different in appearance.
Spruce timber is laser cut with protective paper backing applied to both faces to minimise burn marks and ensure the cleanest result. Occasionally a subtle orange haze discolouration can occur around the surrounding area of the cut line if the backing has not adhered fully to the surface. In most cases these marks are unnoticeable but they can be sanded off with a fine grit wet and dry paper if required.
The average cutting kerf (how much the laser takes away) for spruce 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 brown / orange tone edge.
We have established optimised engraving settings for all our own supply materials. For spruce the marking is a shallow light surface scratching and has a brown / yellow appearance. As as standard we engrave through the protective backing (applied for laser cutting) into the obeche 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, 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.
