What is the Difference Between Raster and Vector Motions When Laser Cutting?

When processing a design file there are two distinct ways the laser system handles different elements of the design — raster motion and vector motion. Here’s a brief description of the difference between the two:

Raster Motion

Raster motion is overlapping left-to-right/right-to-left movement of the optics carriage. It is used for laser engraving, marking, and photo imaging.

Universal Laser Systems’ ULS control software will parse design files for bitmap images, text, and filled areas, and interpret these elements as raster objects. It then automatically calculates raster processing patterns for the laser system. Overlapping left-to-right/right-to-left motion creates a filled rectangle, like this:

Vector Motion

Vector motion is used for laser cutting, scoring, and some marking. In these cases the laser system’s X-Y axis motion system simultaneously moves in two dimensions along the path to match the shape being processed.

The ULS laser system control software will parse design files and interpret thin lines as vector objects. It then calculates 2D vector paths for the laser cutting, engraving, and marking machine.
