We have several CO2 laser machines which generate a laser beam of infrared wave length which is then focused to a point to cut through materials. This process involves immense heat and is suitable for only certain materials and can have an affect on materials. As an example "wood burns", this may seem obvious but unlike cutting timber with a saw or a drill the edges of the cut will be burnt to a fine charcoal and if you for were to get close and sniff it, it will smell. More seriously some materials may "cut" but release chemicals in the process which are harmful to humans or the machine itself. Materials we use include acrylic (also know by brands such as Perspex and Plexiglas), wood, bamboo, leather, EVA, BoPET (Mylar), HIPS and other enginerring plastics.
