Acrylic board is the most commonly used engraving material. It is easy to be cut and carved into various shapes and sizes with lower cost.

Acrylic board has two production processes: Casting and extrusion. Laser engraving mainly uses casting acrylic board to complete. The frosting effect is very white, which is in sharp contrast with the original transparent texture. Acrylic extrusion board is still transparent after carving, and there is not enough contrast effect.

Acrylic generally adopts the back carving method, that is, carving from the front and viewing from the back can make the finished product more three-dimensional. When carving on the back, the image should be mirrored first, and the carving speed should be fast and the power should be low. If the power is too high, the bottom surface will appear uneven stripes, if you want to carve deeper, you can try to carve several times.

In the case of back carving, we should first carve the off color part deeper, and then use flame polishing to fill the color. Without polishing, the color seen from the front will not be uniform.

In the purchase of acrylic, pay attention to the purity of the board, engraving in a high temperature environment, if the purity of raw materials is not up to standard, it is easy to make the board melt.
