Look, this is the first plane in the world to be created using the new technology of “3D printing”. The airplane was built using only a computer—but it can fly at a speed of 100mph and has a two-meter wingspan.

         It was produced using a special nylon laser printer that builds up something layer-by-layer. The parts were made separately and attached using a “snap fit” technique so the aircraft could be put together without tools in minutes.

         No fasteners at all were used in the manufacture of the plane. Unmanned and electrically powered, the plane can travel in near silence and is also equipped with a small autopilot system. The special production process used is known as “laser sintering (激光烧结)”and allows the designers to create shapes and structures that would normally include costly manufacturing techniques. This technology allows a highly-tailored aircraft to be developed from your own design to first flight in days, while using traditional materials and techniques would take months. And because no tooling is required for manufacture, major changes to the shape and scale of the aircraft can be made with no extra cost.

         Professor Jim Scanlon, who led the team, said, “The process allows the design team to revisit historical techniques and ideas that would have been too expensive using traditional manufacturing.” He added, “This form of structure is very firm and lightweight, but very complex. If it was manufactured traditionally it would require a large number of individually tailored parts that would have to be connected or fastened at great expense.”

         The new printed plane is known as the Southampton University Laser Sintered Aircraft—or SULSA for short—and is part of a wider project using cutting-edge manufacturing techniques. The University of Southampton has been at the leading position of Unmanned Aerial Vehicle development since the early 1990s.

My alarm o’clock rings in my ears at 5:00 every morning. On hearing the ring, I will get out of bed and put on my glasses. The house is quiet as I walk downstairs while my husband and three kids sleep in peace. Instead of going for a long run as usual, today I chose my favorite exercise DVD and started moving. Sweat rolled down my face and into my eyes. My heart beat wildly as I face my body to finish each movement before a mirror. Of course I felt extremely tired towards the end, but a smile spread across my face. I smiled because the DVD was over, and there appeared a brighter smile of success from pushing my body to its extreme limit.

While some people are fond of chocolate, shopping, smoking, or work, what I need is taking exercise to pass each day. People shake their heads when they see me run with sweating heavily through the town. Some look surprised when I refuse to try just one bite of chocolate cake. They seem greatly puzzled by my “no thank you,” or by my choice to just have a vegetable salad. I have come to realize that it doesn’t matter to just say “No.” to any kind of food that I don’t want to eat.

Do you wonder what drives me to roll out of bed at 5:00 a.m. every morning? What makes me refuse ice cream firmly? Commitment—I’m determined to change my life with a way which can not only free me from daily anxiety, but also increase energy and self–confidence. And above all it will surely help me to keep good body shape and maybe extend my life. This is the real reason why there’s a huge smile spreading across my face when I look at myself in the mirror or try on my favorite pair of jeans that now fit me just right and look perfectly on me. I never doubt that I cannot make a difference within myself inside and out without such commitment and sweat.
