Laser cutters create designs and patterns by cutting into materials. It is subtractive manufacturing technology that the machine use a powerful laser beam source to melt, burn, or vaporize material away. A laser cutter typically follows directions from computer numerical control (CNC).
The process starts with an extremely small laser beam that is emitted from a tube when a current passes through. This current causes the laser to reflect off a partial mirror and point through a focal lens in the machine head. Following the vector file that holds the 2D design, the laser beam cuta away at a materials until the image is completed. These laser cutting machines are highly capable of creating finely detailed patterns with a high-quality surface finish. There is a wide range of laser cutting techniques and compatible materials that you can use.
Laser Cutter Materials
Depending on the type of laser that is utilized, there's a wide range of compatible materials available. With the co2 laser cutter, you can use wood, acrylic, leather, glass, plastics, foams, as well as cardboard and other paper materials.
How to Design for Laser Cutting?
When creating a design or pattern for laser cutting, you can use eigher 2D or 3D softare. Laser cutters essentially function like an average 2D inkjet printer but come with drivers that allow the laser cutting machine follow specific designs. While these specific drivers are highly common in 2D design software, there is less support from 3D software.
Graphic design software like Adobe Illustrator and free drawing tools like AutoCAD are ideal 2D programs for laser cutting technology.
Laser Cutting Techniques
Vector Cutting: With vector cutting, the laser beam is continuously fired, cutting directly through the material. This technique is solely used for vector graphics and extremely small lines.
Raster Engraving: Contrary to vector cutting, the rastering process burns off only the top layer of the materials instead of cutting all the way through it. The design is engraved in a different color, integrating the image within the selected materials. To do this, the laser is usually preset to a lower power level. Instead of a high-powered pulsing beam, the laser cutter unfurls finely detailed dots to produce the design without cutting through the material.
