UAV is 3D printed

The development of a small unmanned helicopter known as SARAH (Special Aerial Response Automatic Helicopter) was recently advanced through the use of additive manufacturing.

The UAV, made by Flying-Cam, was originally used exclusively by film makers. However, it is now being increasingly used by to provide imagery for civil aviation authorities and law-enforcement agencies.

Because these varied roles require more iterations, CRP Technology was called in and tasked its additive manufacturing department to come up with a solution. The company was able to provide a fast response time to new requirements and provide the best output quality with its unique proprietary process that uses Windform materials.

The main Flying-Cam parts to use additive manufacturing were the airframe structure, the air guide cooling system, tail units and the main battery connection.

SARAH has a 30 minute flight time with a 5Kg payload. By incorporating efficient aerodynamics, innovative flight modes and modular interchangeable payloads all in a portable unit that is quickly deployable, the UAV is able to provide centimetre precision level aerial 3D imagery.
