Last year, I took a high school class called "Design Tech and Robotics." We had a large warehouse to work in full of power equipment and precision milling tools. My teacher also set up a large trailer in the rear parking lot that took up 20 parking spaces, which we called the "proto-lab." Inside of this lab we had some of our most commonly used tools, including a maker bot and an epilog laser cutter.
At one point in the year, our teacher gave us an assignment to come up with something to cut out of wood using our epilog laser cutter for the purpose of mass production and selling it at our robotics team's craft fair. It was around Christmas time, and the new Star Wars movie was in theaters, so I put the two together and came up with the idea to CAD out easy-to-assemble Star Wars-themed Christmas tree ornaments, both TIE fighters and X-wings. I was pretty good at computer-aided design, so that part was easy. But I had never used the laser cutter before, so it was a little daunting when it was time to go into the proto-lab to use it.
I thought maybe I'd just plug my design in and start laser cutting, but it wasn't that simple. I sent the file through the computer and the laser printer sprung to life, shooting lasers at the wood and over-burning it. It was also printing off center, and was all out of whack. My teacher wasn't pleased that I wasted an entire piece of wood, and came over and asked, "Do you have any idea what you are doing?" I of course didn't. He expected me to know because by this point, most of the other students had already used the laser cutter. He was a little impatient with me, saying things like, "It isn't rocket science." But after 30 minutes of adjustments, he helped me position things properly and I managed to finish my project. My Star Wars ornament was chosen out of 17 projects to be sold at our craft fair. And now I even teach other kids how to craft projects using the epilog laser printer through our school's summer robotics program.
