How a Laser Cutter Works

• Laser focuses on the material

• High heat cuts or engraves

• Air assist reduces burning

• Exhaust removes smoke

Cut vs Engrave

• Cut → thin vector lines

• Engrave → filled shapes or thick lines

• Engraving does not cut through

Color Coding Example

• Red → Cut

• Blue → Score

• Black → Engrave

Colors tell the laser what to do first.
