Laser Cutting: Digital Technique to Cut and Engrave Materials


  Laser Cutting is a digital subtractive fabrication technique that consists of cutting or engravinga material by means of a laser. Laser Cutting can be used on a number of materials such as plastic, wood, cardboard, etc. The process involves cutting material using a powerful and highly accurate laser that focuses on a small area of the material. The high power density results in rapid heating, melting and partial or complete vaporizing of the material. As the heat affected area is small, around 0.5 mm, cut parts show minor deformation. Usually, a computer directs the high-power laser at the material and traces the path.
