Although all our acrylic laser cutters are equipped with a standard exhaust fan for the cutting fumes, we recommend you purchase an extra fume extractor if you want to discharge the fumes indoors. The main component of acrylic is methyl methacrylate, cutting combustion will produce strong irritant gas, it is recommended that customers configure a laser deodorant purification machine, which is better for the environment.
Because of the characteristics of laser focus and the thickness of the acrylic, the unappropriated focal length may deliver bad cutting results on the surface of the acrylic and the bottom part.

Lowering the airflow from the air blower is recommended. Setting an air blower with too high pressure may blow back the melting objects to the plexiglass, which may form an unsmooth cutting surface. Shutting down the air blower may lead to a fire accident. At the same time, removing part of the knife strip on the working table can also improve the cutting quality since the contact point between the working table and the acrylic panel may result in lighting reflection.
Acrylic on the market is divided into extruded acrylic plates and cast acrylic plates. The main difference between cast and extruded acrylic is that cast acrylic is produced by mixing the acrylic liquid ingredients in molds whereas extruded acrylic is produced by an extrusion method. The transparency of the casted acrylic plate is more than 98%, while the extruded acrylic plate is only more than 92%. So in terms of laser cutting and engraving acrylic, choosing good quality cast acrylic plate is the best choice.
