When laser engraving extruded acrylic it remains clear and does not produce much of a contrast. Extruded acrylic, on the other hand is ideal if you are only going to laser cut. The material has a lower melting point which produces an almost flame finished edge from the laser.
The quality of engraving is also affected by the purity of the acrylic. Cheaper acrylic doesn’t usually cut very clean due to inconsistent melting points over the sheet material.
Mirrored reverse side engraving
A common laser engraving technique on clear (cast) acrylic is to mirror the engraving on the back side of the perspex. This produces a ‘look through effect’ from the front of the surface. We will reverse your artwork prior to starting an engraving job like this.
