The use of CO[subscript 2] laser cutters/engravers in technology and engineering education "allows even beginning students to produce professional parts in a very short time [and] empowers and motivates students, helping to bring out their creativity" (Flowers, 2000, p. 11). They are fast, accurate, fun to use, and they facilitate iterative design. Laser machining is essentially a two-dimensional (2D) process. The challenge described in this article was for students to create examples of different ways in which lasers can be used to fabricate products that have 3D geometry. This turned out to be a great vehicle for STEM integration and a tool for teaching process engineering. This article is a review of several ways laser cutters/engravers have been used in one technology and engineering program not just for 2D designs, but to design and prototype products that have three-dimensional (3D) geometry. This progression of ideas begins by addressing 2D geometry.
