The Optimus Prime (擎天柱) model on Zhu Xiaoxuan’s desk looks small–only 30cm high. But it may be the first Transformers (变形金刚) toy made by a 3-D printer (打印机)in China.
Zhu, 14, from Shijiazhuang Foreign Language School, designed it himself. Zhu is a big Transformers fan. In winter vacation, when he saw news that people abroad made many things with 3-D printers, he quickly thought of printing a 3-D model of his favorite Transformer: Optimus Prime.
But where did he start? Zhu went to a local 3-D printing company and found that he first needed to design a digital (数码的) 3-D model. However, the software is much for difficult for a teenager to learn.Feeling challenged, Zhu decided to have a try. He found a video online that showed how to use the microsoft. He watched it and learnt hundreds of computer commands (命令).
After three days of hard work, he built the arms. But they turned out to be too long. Zhu had to re-design it. “The model has 96 parts and almost every part needs to be adjusted (调整). You can imagine how many times I have failed,” Zhu said.
Finally, over 20 days later, Zhu completed the design and had Optimus Prime printed out.
