Wood is easiest to engrave with CO2 laser which will basically burn the wood. Our wood block project included adding custom name to a wood beam. LaserCutz made 2 versions of wood laser engraving, one with outline (scored) and another full line scan engraving (darker text)

PC and ABS plastic changes color to white when excited with fiber laser frequencies, this allows adding custom names and logos on various plastic products such as this small plastic cup which can be used for medical purposes or anything else.

Normally laser has no color as it engraves (burns out material) however stainless steel and titanium metals react differently to variable laser frequency and as result color engraving is possible on both stainless steel and titanium.  In this sample dog photo was engraved on metal plate as a gift. Dog face has holographic look which shines in different colors.  This job was done with our state of the art fiber laser and variable frequency control module.

This project required adding European Union regulatory marking on device prototype ABS plastic enclosure.
