can anyone give me a supplier of suitable material?

Hi Rich

I remember that Rodney mentioned something about this in the following post

4) Cut rubber masks for the monumental engraving industry (they use em as sand blast resists)

The self adhesive rubber is available from sign suppliers , it stops the sand used when blasting from impacting the stone and thus only the areas you peel away are blasted , the rubber is difficult to cut as its thick , but a laser can do far better than a knife or vinyl cutter in this regard, Gives a far deeper engraving than just lasering the mable or granite and its much smoother , applys to the glass thing below. Yopu need NOT use rubber unless you are doing major depth blasting , you can use vinyls as well (laser friendly ones)

Maybe you could use something similar to the rubber masks – I though about the possibilities at the time but never followed it up.

Just a thought.

You can use any stiff NON pvc based plastic thin film , tho 0.6mm styrene or ABS is the cheapest and easiest to get. Other materials are UHI acrylic , thin polycarbonate (discolours edges) PETG etc. You can use cardstock too. Some solvents in paints can affect plastic stencils. In a pinch you can use the Rowmark Flexibrass engraving stock stuff.
