Laser cork engraving and cuting.
Cork is made of the outer bark of the cork oak tree. It has a fine, closed cell structure and low density and provides good insulation for heat and sound. It is also non absorbent to liquids, dust or dirt.

Appearance and grainline
As a natural material, please be aware the tone and grain line can vary from sheet to sheet. Thinner sheets can also be prone to warping.
As a natural material burn marks are caused during the cutting process that are minimized using the following standardized cutting methods.
Compressed air (usually 4 bar of pressure) is used to prevent flaming, scorching and charring on the top surface. In some cases a subtle discolouration can occur around the surrounding area of the cut line (paticularly on thicker plywoods.) These can be easily sanded off with a fine grit wet and dry paper.
Very small flares can occur on the surface where the laser fires at the beginning of the path of a vector line / shape.
On bottom surface burn marks may appear when the laser meets the laser bed. Heat from the laser causes residues on the laser bed to transfer back onto the material.
Cut widths & Kerf
The average cutting kerf for this material is +/- 0.1mm (how much the laser takes away). As a benchmark, we recommend that minimum cut widths be no smaller than the corresponding thickness of the material. See more on min cut widths.
Cork sheet cuts with a dark black edge which produces a lot of black dusty residues.
Raster & Vector engraving
Our standardised setting for engraving cork is a shallow surface marking. Cork engraves with a dark black finish which can produce some slight dusty marks.
If you would like to engrave deeper than our standard settings, you will need to specify this in your job request. Deeper engraving produces more black dusty marks that can dirty the cork surface more.
