Nanoe launches high-permittivity Zetamix TiO₂ ceramic filament for RF applications | VoxelMatters - The heart of additive manufacturing
Nanoe is unveiling its newest ceramic filament, Zetamix TiO₂, at EUCAP 2025, the 19th European Conference on Antennas and Propagation, starting on March 30th. This sinterable titanium dioxide-based material, also known as rutile, delivers an exceptionally high permittivity of approximately 75 with impressively low dielectric losses. Specifically engineered for radiofrequency (RF) applications, this product represents a niche that can be ideally explored via Nanoe’s accessible bound filament technology.
A key feature of Zetamix TiO₂ is its ability to enable the production of significantly lighter and more compact RF parts. Because high permittivity materials can concentrate electromagnetic energy more efficiently, designers can reduce the size of components like dielectric resonators and antennas without sacrificing performance. A direct comparison (in the image below) between a resonator printed in zirconia and one made with the new TiO₂ filament shows how much space and weight can be saved using this advanced material.
The development of the Zetamix TiO₂ filament was a collaborative effort between Nanoe, Thales, and the LEAT laboratory, with support from the Agence Innovation Défense. As the highest permittivity 3D printable ceramic currently available, it enables improved RF miniaturization and complex component manufacturing capabilities. This launch follows Nanoe’s earlier Zetamix Epsilon line, reinforcing the company’s growing portfolio of RF-focused materials.
Sintered TiO₂ has long been valued in RF for its ability to reduce signal losses while maintaining high performance. Now, with Zetamix TiO₂, engineers can 3D print intricate dielectric structures directly, unlocking new possibilities in antenna design, RF filters, waveguides, and more. The new filament is particularly suited for use in aerospace, defense, and high-frequency communications, where space-saving and performance are equally critical.
