Kraetonics LLC has been awarded a two-year, $2 million contract from the Air Force Research Laboratory to develop software tools and manufacturing technologies for next-generation frequency selective surfaces (FSSs). The project, beginning Aug. 8, 2025, and concluding Sept. 10, 2027, will be led by Dr. Raymond C. Rumpf, the company’s chief technology officer. The technology aims to enhance the Air Force’s capabilities in controlling and manipulating radio waves, providing a strategic advantage in modern battle environments.
Frequency selective surfaces are patterned metallic surfaces used on aircraft, ships, autonomous vehicles, munitions, radomes and other platforms to block, redirect, absorb or otherwise control electromagnetic signals. Kraetonics has secured an exclusive license from the University of Texas at El Paso for advanced algorithms capable of wrapping these patterns across irregular and doubly curved surfaces without distorting the metal elements, preserving their electromagnetic performance.
By integrating this technology with Kraetonics’ flagship additive manufacturing software, OmniSlice, Kraetonics will enable rapid design and 3D printing of structures containing the advanced FSS technology. This approach will significantly reduce the time from concept to manufactured device, allowing delivery in a matter of hours.
“This is an extraordinary capability we are developing for the Air Force,” said Rumpf. “It should be impossible to perfectly wrap repeated patterns over curved surfaces, but the algorithms we are using can do it. Combined with OmniSlice, products can be moved from idea to finished hardware in mere hours.”
The initiative aligns with Kraetonics’ mission to create tools and methods that maximize the potential of additive manufacturing in defense platforms. Kraetonics is an ambitious team of disruptive thinkers who develop ideas and tools that help its customers take full advantage of additive manufacturing through innovation, software, and advanced manufacturing techniques.
