SWISSto12 – Revolutionising Satellite Communications with 3D Printing Innovation

In the rapidly evolving world of telecommunications and aerospace, SWISSto12 stands at the forefront of technological advancement. Headquartered in Renens, Vaud, Switzerland, this trailblazing company has redefined how radio frequency (RF) systems and satellite payloads are designed, manufactured, and deployed.
With its slogan “Communications Performance in Space,” SWISSto12 embodies innovation by merging additive manufacturing (3D printing) with advanced radio frequency engineering to deliver high-performance, lightweight, and cost-efficient solutions for space and ground applications. Founded in 2011 as a spin-off from the prestigious Swiss Federal Institute of Technology in Lausanne (EPFL), the company has since become one of Europe’s fastest-growing aerospace and telecommunications firms.
The Genesis of SWISSto12: From Research Lab to Global Space Technology Leader
The story of SWISSto12 began in academic research laboratories at EPFL, where its founders explored the potential of additive manufacturing for high-frequency electromagnetic applications. Recognising the limitations of conventional machining in producing complex RF components, the team developed a revolutionary process to 3D print precision-engineered antennas, waveguides, and filters.
This breakthrough technology quickly caught the attention of aerospace and telecommunication giants. By 2011, SWISSto12 had transitioned from an academic venture into a private company backed by prominent Swiss and European investors. Since then, it has established a strong presence across Switzerland, the United States, and EMEA regions, serving leading global clients in both commercial and defence sectors.
SWISSto12’s Ground-Breaking 3D Printing Technology
Redefining Radio Frequency Engineering
At the core of SWISSto12’s success lies its proprietary and patented 3D printing technology for RF components. Traditional methods of producing metal waveguides and antenna assemblies are limited by geometry, material waste, and assembly complexity. SWISSto12’s additive manufacturing process, however, allows for intricate internal structures and optimised designs previously considered impossible.
This approach results in:
-
Significant weight reduction – vital for space and aerospace missions where every gram counts.
-
Enhanced performance – smoother internal surfaces and precision geometries ensure optimal RF transmission.
-
Design flexibility – components can be customised for unique mission profiles or compact integrations.
-
Cost efficiency – reduced assembly steps and fewer parts translate into lower production and maintenance costs.
These innovations have positioned SWISSto12 as a world leader in high-performance RF solutions, used in satellites, aircraft, naval systems, and ground-based communication platforms.
HummingSat: The Small but Mighty Geostationary Satellite
A New Era in Satellite Telecommunications
Among SWISSto12’s most celebrated achievements is HummingSat, a small yet powerful geostationary telecommunications satellite. Designed to deliver the performance of traditional large satellites at a fraction of the size and cost, HummingSat represents a major leap in the commercial satellite industry.
Developed in collaboration with the European Space Agency (ESA) and other global partners, the HummingSat family offers operators a compact, affordable, and rapidly deployable solution for delivering broadband and communication services across vast regions. Its innovative payloads are built using SWISSto12’s own 3D-printed RF technology, ensuring unmatched reliability and performance.
Advantages of HummingSat
-
Miniaturised Design: Smaller satellite buses reduce launch costs and improve orbital flexibility.
-
High Efficiency: Advanced RF systems maximise power output within compact geometries.
-
Rapid Deployment: Manufacturing and integration timelines are significantly shortened compared to conventional GEO satellites.
-
Scalability: Multiple HummingSats can be deployed in constellation formations for extended coverage.
HummingSat has become a flagship example of how SWISSto12 is changing the paradigm of satellite manufacturing and communication performance in space.
