How thick was the abalone?

It was .050" and I cut it in several passes because I was afraid I would fracture it. It is very delicate and has many varying densities.
I applied glue to the rastered part and pressed the abalone into place with a piece of hardwood and light taps with a hammer. Then sanded it smooth.
Enough to do four names is about $50.

Dave...
When cutting the inside pieces of the plastic, how did you account for the kerf of the laser cut....do you make those pieces slightly larger? Ive not done any inlay, but it's one of those things on the list I'd like to try (...the same for wood intarsia.) Does this technique improve the cut?

There is, or used to be, thin sheets of abalone (abalone-like?) made specifically for laser inlay.
The material also came in other colors and patterns.

Here's a post where Mike Mackenzie elaborates on the inlay process and in an ensuing post, the abalone (Ablam) material I spoke of:

The abalone is a natural shell material with varying degrees of density. I enlarged my drawing by .005" to allow for the kerf and was able to do the first piece but on the second I only enlarged the drawing by .002".
If I were inlaying plastic or wood where I cut through the material I would go back to the .005".
David:
My customer provided the material and requested that I use it as opposed to the thinner ablam.
I used blue painters tape on the underside to keep the material together.
I concur with the remarks by Mike Mackenzie.

The customer's always right!
I've always been fascinated by inlay work. It would be one of the reasons I'd buy a laser.

Jim,
Thank you.
I did a test run on a small piece of the same material which resulted in such a nice snug fit, I decided to run without an adjustment. I used Rowmark's LaserMax material from Johnson Plastics.
Mike offered very sound advice. The figure will likely need to be adjusted based on your machine, as well as the material you are cutting, be it wood, plastic, acrylic, etc.

Did you use typical engraving stock for the three colors?

I'm glad you explained the plaque was intentionally shaped as a trapezoid.
I thought it was a weird camera angle. :-)

So far, Chroma-Crystal would fall under digital imaging. If the subject became rampant, we could create a specific folder.
