Tencent Digital (Compile: Daxie) drones will undoubtedly play an important role in the future. These auto-flight machines have emerged in the areas of package delivery, aerial photography, law enforcement and extreme sports. This type of equipment has entered the scale of production.
Now, engineers from Nanyang Technological University in Singapore have found a new way to not only complete the manufacturing of drones through 3D printing, but also to complete the assembly of their required electronic components.
Philip Keane is a doctoral student working at the university's 3D printing center. The drone he designed uses aviation-grade materials. After being printed in a 3D printer, the product can basically take off directly. Now.
Keane said that the biggest challenge he faces is how to make these electronic devices withstand the high temperatures that occur during the printing process. They overcome this problem by adding some high temperature resistant protective layers outside the device.
His design takes about 14 hours to complete the printing, and it will be suspended 3 times in order to place the corresponding electronic devices in the fuselage. In the end, the drone can be lifted simply by assembling the motor and the propeller.
The printing material used by Keane is called "ULTEMTM 9085", a high-strength, lightweight thermoplastic that was previously used in the manufacture of commercial aircraft. Keane said that with the help of this material, drones are exceptionally strong and can carry more than 60 kilograms of cargo.
At present, the problems in the entire production process have been solved. Keen's next goal is to reduce the weight of the drone itself, while improving its durability and improving the flight mechanics performance.
