Laser Etching Acrylic for Outdoor Applications

This photo is a cast acrylic sign that we made for use at Jimani about 10 years ago. It is on the outside of our building and has been exposed to all elements of the weather here in sunny California for a decade. It just recently struck me just how durable this material is and how well the laser etching held up for an outdoor an application.

We did this with a YAG laser. This was done before fiber lasers were available. This type of mark is done with  surface foaming using this cast acrylic material.
