3D Printing for Rapid Prototyping in Aerospace and Aviation

Additive manufacturing of electronics solves many of the design challenges of the aviation industry. With the level of precision afforded by Nano Dimension’s DragonFly System, it is now possible to print complex, professional PCBs, sensors, antennas and other non-planar electronics that pack more functionality in smaller footprints and customizable parts that were impossible to create before. With onsite printing, there is no need to lose time and money shipping designs out for manufacturing, nor place proprietary IP at risk.

Nano Dimension’s groundbreaking technology makes innovation possible for its aerospace customers. From device miniaturization and customization to increasing precision and printing lightweight parts quickly, 3D printed electronics is fast becoming indispensable for aerospace designers.

With the DragonFly System, aerospace product designers can perform tests and iterate on the go, enabling rapid prototyping, innovative circuit design and Improved performance.

Harris Corporation and Nano Dimension worked together on a study to explore the potential use of 3D printing for radio frequency (RF) circuits for RF systems. The project included designing, simulating, and testing a 3D printed RF amplifier and comparing it with the performance of an amplifier developed with conventional manufacturing techniques, using FR4 substrate material as a baseline.

The study on the advantages of using additive manufacturing to develop RF circuits for wireless systems is part of a joint project with the Israel Innovation Authority and Space Florida Foundation, a partnership promoting research development and the commercialization of aerospace and technology projects.

Test Results

To assess the quality of the 3D printed RF circuit versus one manufactured with traditional methods, Harris used amplifier measurements that tested for small signal gain, input return loss, and output return loss.

The resulting data showed similar RF performance between the 3D printed and the baseline amplifiers, demonstrating the viability of 3D printing technology to produce a functional RF circuit with performance comparable to those developed using conventional manufacturing techniques:

  • There was no noticeable difference in the input or output return loss response over the frequency range from 10 MHz to 6 GHz.
  • No noticeable difference was detected in the gain of the 3D printed circuit and the conventionally manufactured amplifier. The gain difference between the 3-D printed circuit and the conventionally manufactured circuit was less than 1 dB up to 4.7 GHz and less than 1.3 dB up to 6 GHz.

With the DragonFly, circuits and systems that have rigid packaging integrated with flexible circuits can be produced in a single print without the need for cables and connectors.


The performance of the 3D printed RF circuits was comparable with the traditionally manufactured circuits. In addition, the use of in-house 3D printed electronics to make RF amplifiers drastically reduces both the cost and time required per iteration so that RF amplifier manufacturers can iterate several versions in less time than with traditional methods. Other advantages of 3D printed electronics include the ability to save time by evaluating several design variations at one time, and fabricate complex electronic systems that cannot be manufactured by conventional means.


Creating an RF circuit used for conveying information such as data, video and voice across long distances, is typically a long, complex multi-stage process when using conventional manufacturing methods. Consequently, achieving optimum performance is an iterative process: create a design, produce the RF circuit, test its performance, improve the design, and repeat the process until an optimum design is reached. In practice, optimizing performance in this manner can be expensive and lead times are long.

Using Nano Dimension’s DragonFly System, Harris was able to 3D print functional RF circuits. A 101mm x 38mm (4” x 1.5”) x 3mm thick circuit was 3D printed in 10 hours. Nano Dimension’s silver nanoparticle conductive and dielectric inks were used to create the functional electronic parts in a single print and then components were manually soldered to the PCB.
