3D printer makes his dream come true

Wang Tielin, a student of the Electromechanical Engineering of the Optoelectronic Information College of Changchun University of Science and Technology, has a college student mechanical innovation base in the college. As long as he is not busy with his studies, he goes to the laboratory to print drone parts with like-minded students with a 3D printer. These drone parts are designed and manufactured by Wang himself. Every time he made drone parts, he sold them all over the country through the Internet. He has a dream of starting a business after graduation and selling the drone parts he designed and manufactured to the world.

Wang mainly studies the use of 3D printing technology to manufacture drone parts. “Generally, simpler and smaller parts require more than an hour to print, and larger ones take longer. In addition, a lot of effort is required in the early design.” Wang took out a drawing and a computer, the drawing is his hand-drawn part pattern, and the computer is for 3D modeling use.

When it comes to the design process, Wang said that there is no fixed time. If there is no inspiration, you may not be able to come up with a satisfactory design in a month; if you have the inspiration, you may be able to design a more perfect part with just a few strokes. “Now there are not many people in Jilin Province who design their own racks and parts. Those who can stick to it are all emotion-driven.”

At present, Wang has completed the “Iron Anchor II” traversing machine frame. Its acceleration capability is particularly strong, and the thrust-to-weight ratio is particularly large. It can reach a maximum speed of 180 km/h in two seconds. In addition, his second-generation racks and a large number of parts have been sold to various places through the Internet.

Speaking of the future, Wang hopes that he can develop his hobby into a career: “I hope that one day in the future, I can sell the parts and racks I designed to all over the world, and I hope to participate in higher-level competitions.”
