Background

Applications listed below show the versatility of 3D printing in the rapid prototyping and manufacturing of critical drone components and structures. Similar to the aviation industry, the drone industry benefits from 3d printing in drone performance, efficiency, and customization of drone design. The primary benefits over traditional manufacturing methods are the capabilities to print complex, lightweight designs, and use strong carbon fiber reinforced materials. A 3D printed carbon fiber drone frame can ensure the drone is both lightweight and strong. There are many different types of drone technology, but most drone manufacturers use 3d printers at some stage in their drone production. From a simple quadcopter drone to more advanced unmanned aerial vehicles and autonomous drones, 3 d printing technology has something for the entire drone market. In the drone market, some drones are referred to by the term remote piloted aircraft (RPA). The key applications of 3D printing in drone manufacturing are summarized below.

Applications:

Payload Enclosures / Attachments

3D printing is used to fabricate enclosures and attachments for various payloads, such as sensors, cameras, and other mission-specific equipment.

Conformable Fuel Tank

Additive manufacturing enables the creation of conformable fuel tanks that can be tailored to fit specific spaces within the drones, optimizing fuel storage capacity.

Battery Compartment

Additive manufacturing is used to create custom-designed battery compartments for efficient and secure battery placement.

Oil Tank / Glycol / Hydraulic Fluids

3D printing enables the production of tanks and containers for storing oil, glycol, hydraulic fluids, and other essential fluids used in drone operations.

Avionics and Radio enclosures

3D printing is utilized in drone manufacturing for enclosures for avionics and radio equipment, protecting sensitive electronics from environmental elements. 3D printed drones may require a specialty ESD building material to shield electronics from charge. For example, ABS ESD-7 or other like material.

Shrouds and Closeouts

3D printing is employed to produce shrouds and closeouts that streamline the aerodynamics of the drones and protect internal drone components.

Wing Structures

3D printing is utilized to manufacture wing structures, offering lightweight and strong components to improve flight performance. These designs likely could not be created using traditional manual methods.

Aileron Flaps

Additive manufacturing is employed to fabricate aileron flaps, contributing to the RPA’s control and maneuverability during flight.

Aerodynamic Surfaces

A 3d printer can be used to create aerodynamic surfaces that optimize the drone’s performance and stability in flight.

Connectors / Reducers

3D printing is employed to produce connectors and reducers that facilitate the integration of different components and systems in the drone.

Wire Ways / Conduits / Connectors

Additive manufacturing enables the creation of pathways and conduits to route wires and cables neatly throughout the RPA.

Clips / Clamps / Grommets

3D printing is used to fabricate clips, clamps, and grommets that secure various components in place during drone operations.

Hydraulics Supports and Standoffs

Additive manufacturing is employed to create supports and standoffs for hydraulic components, maintaining proper positioning and alignment.

Fuselage Components

3D printing is utilized to manufacture components for the RPA’s fuselage, such as access panels and structural elements.

Component Connectors

Additive manufacturing is used to produce connectors that join different components and systems within the RPA.

Air Filter Boxes / Air Ducting

3D printing enables the creation of air filter boxes and ducting to regulate airflow for cooling and ventilation.

External Camera and Gimbal

Additive manufacturing is employed to create mounts and housings for external cameras and gimbal systems used in surveillance and imaging.

Air Intake Manifolds

3D printing is utilized to fabricate air intake manifolds, crucial components of the RPA’s propulsion system.

Brackets

Additive manufacturing is used to produce brackets that support various components and systems within the RPA.

Mounting for PODS / Avionics and Electrical Systems

3D printing enables the creation of custom mounts for PODS, avionics, and electrical systems in the RPA.

Conclusion

There are nearly endless possibilities for using 3d printers to manufacture drone parts to create a final product. As more high-performance capabilities are needed for drone delivery, drone racing, and defense applications, drone manufacturing will continue to move away from traditional manufacturing methods. Here we only covered end use drone parts, but there are plenty of ways that 3d printers can be used alongside traditional manufacturing methods. These include sacrificial tooling for carbon fiber layups, rapid prototyping, and creating molds for polyurethane foam. Aerial additive manufacturing is helping to revolutionize the drone market.
