Existing Laser Cutter DesignsLaser cutters for modeling and engravingThese laser cutters are versatile tools for cutting for prototyping and low-volume manufacturing. They typically consist of a downward-facing laser mounted on an X-Y positioning mechanism similar to that used in pen plotters. Sheets of various materials- plastic, paper, fabric, etc. are placed under the working area of the laser mechanism. As it sweeps back and forth over the material surface, the laser beam vaporizes the material in a small channel beneath it. The resulting cuts are accurate and precise, and require no surface finishing. Click the following image for an MPEG video of the Universal Laser Systems laser cutter.
In general, use of these systems has been confined to large institutions, design companies, and custom engraving shops. Some popular models are visible at the following links:
Laser cutters have a variety of advantages over other manufacturing technologies. They usually can accept data directly from a personal computer. Unlike computer numerically-controlled (CNC) mills, they are safe, clean, and require little maintenance. In addition, they are fairly fast in operation, and can cut a wide variety of flat materials. As most existing laser cutters cost between $20k to $200K, they are affordable only for moderately sized industrial operations. Clearly, a price reduction of two orders of magnitude would dramatically increase their suitability to entirely different environments, such as the home.
