Ceramic 3D printing with unparalleled precision.

/ What is ceramic 3D-printing?

Ceramic 3D printing with XJet technology is a forward-thinking and innovative manufacturing method for ceramics that functions like an advanced inkjet printer. Unlike powder- and laser-based processes, nanoparticles in liquid form are deposited layer by layer and then sintered into strong, solid, and highly durable components. This approach to ceramic 3D printing offers exceptional detail accuracy, reliable and predictable results, and a high production speed.

/ design products with unlimited freedom

Ceramic components that require internal channels, extremely thin walls, or tolerances below 50 micrometers are often difficult to manufacture using traditional production methods. Techniques such as milling, pressing, and injection molding encounter geometric limitations, particularly in complex high-tech applications.

With ceramic 3D printing using XJet’s NanoParticle Jetting™ (NPJ), previously existing limitations are overcome. This technology functions as an industrial inkjet printer specifically designed for ceramic materials. Instead of traditional powders and lasers, it uses liquid cartridges containing billions of suspended nanoparticles. The part is digitally built layer by layer in layers of 7 to 10 microns, including a soluble support structure that is essential for print quality.

After the printing process, the support can easily be removed in water, after which the part is sintered into a solid ceramic component with an exceptional density of more than 99.5%. This innovative approach guarantees accuracy and reliability in applications where high performance is required.

/ What are the concrete benefits for you?

• Minimum feature size of 150–200 microns
• Dimensional accuracy up to ± 50 microns
• More than 99.5% density with extremely low porosity
• Ultra-thin layers of 7–10 microns for highly detailed surface finishes
• Soluble support structures for complex internal geometries
• Smooth surface finish (Ra 1–3 μm), often without the need for post-processing
• High precision and reliable dimensional consistency

Because the process is fully digitally controlled and shrinkage during sintering occurs isotropically (uniformly in all directions), dimensional accuracy is reliable and reproducible. This results in fewer iterations, fewer correction cycles, and a higher chance of successful production on the first attempt.

The combination of nanoparticles and soluble support structures enables geometries that are not achievable with traditional manufacturing techniques, such as internal cooling channels, hollow structures, complex overhangs, and components within other components. At the same time, the process preserves the industrial material properties of the ceramic, including isotropic strength, extremely low porosity, and high resistance to both thermal and chemical influences.

/ clean, safe and efficient production

Because the process uses sealed cartridges instead of loose powders, it is both clean and safe. There is no risk of explosions or exposure to fine dust, while material waste is also significantly reduced. This makes the system not only technically attractive but also highly practical for use in industrial environments.

/ for high-tech applications where precision matters

Ceramic 3D printing with NPJ offers valuable opportunities for applications where complexity, precision, and reliability are essential. This includes medical instruments, aerospace components, RF parts, and wear-resistant high-tech solutions.

/ FAQ

1. How strong is 3D-printed zirconia compared to traditionally pressed ceramics?

3D-printed zirconia using NanoParticle Jetting™ (NPJ) achieves a density of over 99.5% after sintering. This provides isotropic strength comparable to traditionally pressed or milled ceramics. Because the material is built evenly, layer by layer, mechanical and thermal properties remain consistent, while complex geometries can also be easily realized.


2. Can I produce small precision ceramic parts without expensive molds?

Absolutely! NPJ technology is fully digital and does not rely on molds or dies. This makes it ideal for small series, prototypes, or high-precision parts. With minimum feature sizes of 150–200 microns and tolerances up to ±50 microns, even complex, small precision components can be manufactured without additional tooling costs.
