In the design file, the laser cutting lines should be marked in red—# ff0000 or 255,0,0—with a “hairline” thickness. Choose a thickness of 0.001mm when working with software that does not allow you to set the hairline thickness, and 0.000mm when working with CAD programmes. Cut lines should be created on a separate design layer, which is best described as cutting.
Laser cutting sheet metal requires precise designs where dimension precision is critical. Therefore, while constructing them, keep in mind that the actual thickness of the laser cutting line ranges from 0.05 to around 0.10 mm depending on the type of material and its thickness.
Furthermore, it is important to ensure that no laser cutting line in the project is duplicated because if this occurs, the laser cutter will cut numerous times in the same spot, resulting in a significantly thicker and lower quality cutting edge, thus increasing the cost of laser cutting.
