Extruded Acrylic (XT)
Extruded acrylic is created by pressing an acrylic mass through a "die" (a mechanism similar to a nozzle). The process resembles how cake frosting is pressed through a piping bag tip.
This production method gives the extruded acrylic different mechanical properties than cast acrylic. In addition, it has a comparatively lower thickness tolerance (±5%). Extruded acrylic has a lower production cost, and is thus economical when produced in high volumes.
As a rule of thumb, processing extruded acrylic requires less laser power than does equally thick cast acrylic material. When extruded acrylic is cut with a laser, flame polished edges are created, which tend to be sharper on one side of the material. Laser engraving extruded acrylic is not recommended due to the unclear, matte grey finishing (see the image above).
