Which materials can I use on my laser machine? Return to top of page

There are a wide range of materials which can be safely laser cut and engraved, but there are some materials which may need some additional safety considerations before processing, and some which are best avoided.

You can always contact your material supplier to obtain the COSHH data sheet for your materials to check how they will react to heat, but we have also put together a list of the more common materials, and additional information about their compatibility with a laser here.


What settings should I use on different materials? Return to top of page

Specific materials and material thicknesses will need different settings in the laser machine speed and power to process correctly, depending on the effect that you are looking to achieve. More information can be found here.


What focal height should I be using? Return to top of page

When your laser machine was first installed, a focus gauge was supplied with the machine.

Instruction on how to use the focus gauge can be found here.

A tutorial on how to make a replacement focus gauge can be downloaded here.


Marking plain metals with a CO2 laser Return to top of page

Click here to see our step-by-step guide on how to do this.

You will need a metal marking solution (aerosol / tape / paste) to enable your CO2 laser machine to mark the metal.


Engraving mirrors or mirror acrylic Return to top of page

Engraving on mirrored materials can be very effective by engraving the reverse of the material to remove the reflective backing. When looking at the front of the material, this will then give you patters or areas where the mirror does not reflect, creating a striking contrast.
