Ceramic Binder Jetting
— Complex Ceramic Parts Without Tooling
Produce high-performance ceramic components directly from CAD — no molds, no machining, no limits on geometry. SiC, Alumina, Zirconia. 8–12 L/h throughput. From R&D prototypes to production volumes. Upload your file — we will show you what is possible.
Why Binder Jetting for Ceramics?
Traditional ceramic manufacturing requires expensive tooling — dry pressing dies, injection molds, or slip casting setups. Binder Jetting eliminates all of that. Print complex geometries directly, then sinter to full density.

Where Ceramic Binder Jetting Delivers
Applications where the combination of complex geometry, hard ceramics, and low-to-medium volumes makes BJ the clear winner.
🔌 Semiconductor Equipment
SiC wafer handling components, plasma-resistant chamber parts, electrostatic chucks. High-purity SiC — no metallic contamination. Complex internal channels for gas distribution and thermal management printed directly.
⚙ Wear-Resistant Components
SiC and alumina pump seals, bearing sleeves, valve seats, sandblasting nozzles. BJ enables internal features that would otherwise require expensive diamond grinding — at a fraction of the cost.
🏥 Medical Ceramics
Zirconia dental crowns and bridges, alumina femoral heads, custom ceramic surgical guides. ISO 13485 certified production. Patient-specific geometry without custom tooling.
🔥 High-Temperature Furnace Hardware
SiC kiln furniture, thermocouple protection tubes, crucibles. Sustained operation at 1200–1600°C in oxidizing atmospheres. Complex shapes printed to near-net — minimal post-sintering grinding.
✈ Aerospace CMCs
SiC/SiC composite preforms for turbine shrouds, thermal protection tiles, radomes. BJ preform + PIP or CVI infiltration. Complex fiber architecture impossible with layup techniques.
🔧 Investment Casting Cores
Water-soluble ceramic cores for single-crystal turbine blade casting. BJ enables serpentine cooling passages impossible with traditional core injection. Dissolved out after casting — zero mechanical extraction.
⚡ Electronics & Sensors
Alumina substrates and insulators with integrated mounting features. Sensor housings for harsh environments. BJ prints the complete geometry — no post-machining of brittle ceramic needed.
🌎 Nuclear & Energy
SiC/SiC accident-tolerant fuel cladding, fusion first-wall components, CSP receiver tubes. Radiation-resistant ceramics with complex coolant channel geometries.
🛠 General Industrial Ceramics
Custom insulators, spacers, guides, and fixtures. When you need 50 pieces of a ceramic part that doesn't exist off-the-shelf — BJ prints them in 2 weeks with zero tooling investment.

Frequently Asked Questions
Silicon carbide (SiC), alumina (Al2O3), and zirconia (ZrO2) are our production-qualified materials. We also print ceramic matrix composite preforms (SiC/SiC, C/SiC) and water-soluble ceramic cores for investment casting. For proprietary powders, we develop custom binder formulations — typically 4–8 weeks to qualify a new material.
Up to approximately 800×500×400mm in the green state (J800P). After sintering, parts shrink predictably ~15–25% depending on material. Final dimensions up to ~640×400×320mm for SiC. Larger assemblies can be produced by joining multiple segments.
Print resolution: 400–1200 dpi. After sintering, dimensional accuracy is typically within ±1–2% accounting for predictable shrinkage (compensated in the CAD model). For tighter tolerances, we offer post-sintering diamond grinding and polishing.
No. From single R&D prototype parts (J160R) to full production runs (J800P), the same process and quality standards apply. Single prototypes typically ship in 10–15 business days.
For 1–10,000 parts, BJ is typically more cost-effective than pressing, slip casting, or injection molding — because tooling is eliminated. For very high volumes (>50,000 identical parts), traditional pressing may be cheaper per part. BJ is especially competitive for complex geometries where traditional tooling would be expensive or impossible to fabricate. Contact us for a part-specific comparison.

Minimum wall thickness: 0.3-0.5mm for SiC, 0.5-1.0mm for Al2O3 (depending on geometry). Layer thickness: 0.1-0.3mm. Post-sintering shrinkage is compensated in software. We provide as-printed and sintered tolerance data with every job.
