Abstract
A method of scribing a graphic on a material is provided, in which laser output is applied to the material. The laser output is moved relative to the material at a high speed greater than 10 m per second, and at a high power greater than 500 W, to scribe a graphic on a surface of the material. Also provided is a system for scribing a graphic on a material. The method and system of the invention are especially useful in the scribing of building materials.
Claims12
A method of laser scribing a graphic onto a workpiece, comprising:
- applying control information from a controller operable at a controller speed in a range of 10,000 pixels per second to 50,000 pixels per second to a laser operated to produce a laser beam, and laser scribing a graphic onto a surface of a workpiece with the laser beam based on the control information, said laser scribing comprises moving the laser beam at a relative scan speed in a range of 10 m/s to 50 m/s and lasing the surface of the workpiece without burning through the workpiece, wherein the laser is operable to produce the laser beam with a power output in a range of 500 W to 5000 W.
A method of imparting a visually perceptible change to a workpiece, comprising:
- providing a laser and an operably associated controller operable to change the power output every 1 to 4 pixels;
- providing a workpiece;
- providing a controller operable at a controller speed in a range of 10,000 pixels per second to 50,000 pixels per second;
- selecting denim as the workpiece;
- applying control information from the controller to the laser to produce a laser beam having a power output;
- and
- laser scribing a graphic onto the workpiece using the laser beam of the laser based on the control information.
A method of imparting a visually perceptible change to a workpiece, comprising:
