Can you laser engrave on acrylic paint?
I found acrylic paint (water based) works the best, although a bit pain in the butt to apply. I use q-tips to fill pain in the the engravings, let it dry for few minutes, then wipe with very slightly damp cloth. Trick is in timing for paint to dry and amount of moisture on the cloth. It's a delicate balance.
Our acrylic paints are designed for fill reverse engraved areas on signs or applications. Specially designed to use on laser engraved plastics our acrylic filler paints will not affect nor “craze” the lasered area.

Cast acrylic is ideal for laser engraving because it creates a frosted surface. Common trade names for cast acrylic are Lucite™, Acrylite™, Shinkolite™A and Hesa™-Glas.

Enamel-based acrylic paints are designed to adhere to glass and look transparent or vibrant, depending on the number of coats you apply. The versatility and range of colors of these paints make them ideal for almost any etched glass project.
Laser marking on paint
Laser marking precisely removes and carbonizes extremely thin paint layers from a wide variety of materials. When using a laser marking machine for engraving on paint, a bit of the material is ablated from the surface.
No enameling experience is required. After enameling students will mark the enamel using a laser engraver. After the enamel is engraved students will learn basic Limoges painting techniques to create one-of-a kind jewelry compositions.

Does acrylic block laser?
Acrylic also usually has lower VLT ratings than glass, though it still offers ample protection from lasers.
In 3mm acrylic you can expect around 0.25mm (0.01″) deep, and in some of the woods the laser will cut up to 0.5mm (0.02″) deep. To go further into the material than this will increase the risk of undesirable damage such as warping (in acrylic) and excessive burning (in timber).
Laser Cutting Speeds
Cutting acrylic is usually best achieved with relatively slow speed and high power. This cutting process allows the laser beam to melt the edges of the acrylic and essentially produce a flame-polished edge.
