Too much air, however, forces the molten acrylic to dry too quickly and will result in a bubbly and cloudy edge. The air helps push the acrylic emis- sions down into the cut so that the fume extraction and dust collection system can then extract the debris. The laser and the exhaust system's ability to remove the gas helps keep any staining from occurring around the edges, so the more CFM, the better. It is also helpful to equip your laser sys- tem with a vacuum table, if possible. This accessory not only fixes various materials to the working table using a light vacuum to ensure material stability and correct focus- ing over the entire surface, but it also cre- ates a downdraft, which pulls the flame down completely through the material. With so many factors contributing to the acrylic laser cutting process, it is clear why a suitable approach is vital. If you understand your acrylic types, capabili- ties of your laser system, and supporting machine accessories, then you, too, can skillfully laser cut acrylic and achieve high- quality edges.
