The polymer craft could form the basis of cheap and potentially disposable UAVs that could be built and deployed in remote situations potentially within as little as 24 hours, researchers said.
The 1.5 m-wide UAV, developed by Sheffield university, comprises nine parts that can be snapped together and has already successfully completed a test flight as a glider.
It weighs less than 2kg and is made from thermoplastic. The engineers are currently evaluating the potential of nylon as a printing material that would make the UAV 60 per cent stronger with no increase in weight.
Using support material adds a direct material cost, and significantly increases build time, in some cases by an order of magnitude. This is a result of the machine having to change between build and support structure heads after each printed layer.
New 3D printing techniques, such as the fused deposition modelling (FDM) used to make the UAV at Sheffield, could soon be used in the creation of products without the need for complex and expensive tooling and the time required in traditional manufacturing.
They plan to develop the craft for guidance by Global Positioning System (GPS) or camera technology, controlled by an operator wearing first person-view goggles.
"Following successful flight testing, we are working to incorporate blended winglets and twin ducted fan propulsion," said Dr Garth Nicholson who led the project.
"We are also investigating full on-board data logging of flight parameters, autonomous operation by GPS, and control by surface morphing technology. Concepts for novel ducted fan designs are also being investigated," Nicholson said.
