Etch Deep into Acrylic, but not Cut Through?

[AliceTut]

I have access to a 60W Epilog and a 100W Trotec. I want to create something like a die or a photopolymer plate for debossing into card stock.
To do so I need to cut away large chunks of the die material. But, to keep all of the elements in place, I would like to etch deep into the material, leaving connections between them which won't hit the paper.
My first thought would be to use acrylic, mounting the "die" on something big and flat (like a thicker piece of acrylic).
The question is, can I cut away chunks of acrylic without cutting all the way through? If not is there a material you guys would recommend? Maybe a bunch of passes on some piece of hard wood might work?

Thanks,
Gary

Fixtureman is correct just engrave what ever material you choose just like you were making a rubber stamp, wood, acrylic what ever, derlin works well for this also.
