The Epilog laser machine in the prototype lab uses a highly focused, high-power beam of light to vaporize or burn materials (such as wood or acrylic) in a precise, computer-controlled path. The laser can also engrave surfaces by moving back and forth to etch surfaces without cutting through them.

Key Components and Functionality

Laser Source: Typically CO2 (for non-metals) or fiber (for metals) lasers, which generate the infrared light beam.
Mirrors & Lens: The beam is reflected by mirrors and focused by a lens into an intensely hot, small point (similar to a magnifying glass) on the surface.
Motion Control: The laser head moves rapidly across the material (in x and y axes), controlled by software, to trace the digital design.
Process - Engraving (Rastering): The laser burns away the top surface layer, creating a shallow mark, often moving back and forth like an inkjet printer.
Process - Cutting (Vectoring): The laser uses higher power to move along a line, vaporizing the material entirely through its thickness.

Settings

Each type of material used in the laser cutter has unique process settings. The settings include the power, speed, and frequency.
