I wanted to color the labels on an acrylic box for a Raspberry Pi enclosure with a paint. This method uses a powder which is etched into the laser engraving. The powder used is called LaserDarc
. I bought a sample of 3 colors for around $70.
The Raspberry Pi enclosure pattern was from Thingiverse
The laser used was the Trotec Speedy 300 at my local Techshop. This instructable assumes you already know how to cut and etch acrylic on your laser.
