Deep laser engraving of aluminum using a paint removal process. The powder-coated red aluminum part was laser marked using the i-Series Fiber Laser Kit with a 254mm lens. The part was engraved with a frequency of 50 kHz. The fastest method to remove the paint was to mark each letter in the logo individually. Removing the paint going letter by letter gave the paintless time to cool of resulting in a much faster cycle time. The red part with 0.0045″ coating needed 140 seconds to be removed.
