Laser Engraving Colour Fill Tutorial - Part 1: Wood


Often our laser cutters are set into the production line tirelessly running through jobs which although critical can be highly repetitive. It is easy to forget that as well providing cutting solutions these machines can create great pieces for exhibition stands, your most valued clients or maybe you just want to have a bit of fun with your laser cutting machine.

Today we will be covering a different way that you can laser process wood. In this post we will look at using paint to fill wood.

What you will need:

  • Wood
  • Masking/Transfer tape
  • Clear lacquer spray
  • Spray paint

1.     Begin by covering the wood with wide masking or transfer tape.


2.     Then ensure you have no air bubbles trapped between the tape and the wooden surface. 

3.     Next up its time to put the material into the laser and prepare the graphic. Your graphic should only contain black for the engraving – no greys. This will give you a nice consistent depth and finish to the engraving.  TIP: if you want a slightly deeper engraving increase the intensity adjustment under raster.


4.     After the engraving is finished remove the work piece and apply a coat of clear lacquer. This will seal the wood and stop the colour from soaking into the material giving a crisper edge finish.

NOTE: Mixing lacquer and polyurethane can cause a reaction making the wood appear white – only use one.

5.     Once the clear coat has completely dried apply the coloured spray paint. Multiple coats are recommended for best results but make sure to let the paint dry between layers. 


6.     Once the paint is completely dry carefully remove the masking tape to reveal the finished product!
