Zetamix TiO2 filament lets you 3D-print dense titanium-dioxide (rutile) ceramic with a very high dielectric constant on a standard FFF printer, then debind and sinter to a functional RF part — the same print → debind → sinter workflow we run in-house on our 3DCeram M.A.T. Permittivity εr = 75 (±5) at 9.4 GHz makes it a material for miniaturized microwave devices, antennas and dielectric resonators.
Why engineers choose Zetamix TiO2 filament
Sintered titanium dioxide (rutile) with a very high, batch-consistent dielectric constant — for RF and microwave parts.
Dielectric constant εr = 75 (±5) at 9.4 GHz lets you shrink RF components and antennas that would be far larger in low-ε materials.
Loss tangent of 1×10⁻³ to 5×10⁻³ keeps dielectric losses low at microwave frequencies.
Titanium dioxide (rutile), 81% by mass, sintered to 98–99% of theoretical density for stable, repeatable RF behaviour.
Consistent permittivity and loss from spool to spool, with ±5% dielectric stability from −50 °C to +110 °C.

Full specifications are listed in the Specifications tab. Dielectric and density values are process-dependent — final properties vary with print, debind and sinter parameters.
From spool to dense rutile ceramic part
Three stages — the same workflow we run in-house.
Design & scale
Scale the model by 123.4% (X/Y) and 125.7% (Z) for sintering shrinkage. Design for the RF geometry and target frequency you need.
Print on FFF
Print the green part on any standard FFF machine with a grooved drive gear and flexible build plate. No cooling fan; 0.5 mm retraction at 80 mm/s.
Debind & sinter
Acetone debind (6 h, 40 °C), thermal debind to 500 °C, then sinter to 1300 °C in air to a dense rutile part. No furnace? We run this for you.
Where Zetamix TiO2 is used
Engineers print TiO2 when they need a high-permittivity dielectric in a complex, miniaturized RF geometry.

Watch how Zetamix ceramic and metal filaments go from spool to dense, sintered part — the same FFF print → debind → sinter workflow we run in-house.
Choose your Zetamix material
Every Zetamix filament prints on a standard FFF 3D printer — we print and validate them in-house on our 3DCeram M.A.T. system — then debind and sinter to a dense ceramic or metal part. The highlighted row is the material on this page; compare the range below:
