FAQs
What makes TiO2 particularly valuable for RF applications?
TiO2 (rutile) offers an exceptionally high dielectric constant (ε=75) with low loss, enabling miniaturization of RF components while maintaining performance—ideal for antennas, filters, and waveguides.
How stable are the dielectric properties with temperature?
Excellent stability—the dielectric constant varies only ±5% across a wide temperature range from -50°C to +110°C, making it suitable for demanding environmental conditions.
What RF applications is this material best suited for?
Microwave antennas, waveguide components, RF filters, dielectric resonators, phase array systems, and any application requiring high permittivity with low loss at microwave frequencies.
How does the sintering process affect dielectric properties?
Proper sintering to 1300°C achieves 98-99% density, which is crucial for consistent dielectric performance. Lower densities may reduce the permittivity value.
What design limitations should I consider?
Standard ceramic design rules apply—avoid sharp corners, maintain uniform wall thicknesses where possible, and account for anisotropic shrinkage (different in X/Y vs Z).
Can I create complex geometries with internal features?
Yes! This is a key advantage over traditional ceramic manufacturing. Create intricate waveguide structures, complex antenna shapes, and internal channels impossible with conventional methods.
How long does the complete process take?
Printing varies by model. Chemical debinding takes 6h + 2h drying, thermal debinding ≈60h, and sintering ≈43h including ramp times and holding.
What safety precautions are necessary?
Standard ceramic filament handling—use in well-ventilated areas during printing and debinding. The sintered TiO2 is biologically inert and safe for handling.
What’s the shelf life of the filament?
Six months when stored in original vacuum-sealed packaging in cool, dry conditions
Can I achieve different permittivity values?
The ε=75 is characteristic of fully dense rutile TiO2. Variations in sintering density or the use of composite designs can modify effective permittivity for specific applications

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:
