Laser Cutter

The laser cutter is located in the southeast corner of the wind tunnel lab, and can be used to cut thin, soft materials(woods, plastics, etc.) and to engrave anodized metals.

Using CorelDraw to Create an Image


CorelDraw functions like most other drawing programs. Along the left side of the screen are different drawing tool. In CorelDraw you can create shapes and lettering, scale objects, and set lines to either thick or thin, red or black. Black is used for when you want to make the laser cutter shade a shade or area without cutting through. This is called rastering. Red tells the laser cutter to cut through the material. You should only use thin red lines for cutting, thick red lines will cause the laser cutter to cut the same pattern about 8 times.
