英文摘要：

This paper designed a quadrotor helicopter based on 3Dprinting technology.According to the features of quadrotor helicopter,we made a detailed analysis of the quadrotor＇s flight principle,the innovation and improvement of the structure in order to make a mechanical simulation analysis for the key parts of 3Dprinting.The results show that it is easy to manufacture the body of the aircraft to realize the prototyping vehicle with personal design through 3Dprinting technology which made rapid.Compared with the conventional aircraft,the final quadrotor has stronger maneuverability,smaller size and smarter performance,which also has broad application prospects.
