What Ceramic Materials Are Commonly Used in Binder Jetting?

Overview of Ceramic Binder Jetting

Binder Jetting is well-suited for producing ceramic components with moderate to high complexity in large quantities. The process involves selectively depositing a binder onto a ceramic powder bed to form a green part, which is then sintered to achieve final strength and density. Binder Jetting does not involve localized heat during printing, allowing for rapid build rates, no support structures, and easy scalability.

Common Ceramic Materials Used in Binder Jetting

Alumina (Al₂O₃)

Alumina is the most widely used ceramic in Binder Jetting due to its excellent electrical insulation, high hardness, and thermal resistance.

• Dielectric strength: >10 kV/mm

• Applications: Electrical insulators, wear-resistant parts, and biomedical components

Silicon Carbide (SiC)

Silicon Carbide is valued for its high thermal conductivity, hardness, and resistance to corrosion and wear.

• Operating temperature: >1,400°C

• Applications: Heat exchangers, mechanical seals, and high-load structural parts

Silicon Dioxide (SiO₂)

Silicon Dioxide is commonly used for low-density, thermally stable parts.

• High dimensional stability

• Applications: Casting cores, investment molds, and lightweight structural elements

Zirconia (ZrO₂)

Zirconia is utilized for its fracture toughness, biocompatibility, and thermal insulation.

• Fracture toughness: ~7–10 MPa·m½

• Applications: Dental crowns, oxygen sensors, and structural implants

Glass-Filled Ceramics

Glass-filled ceramics offer enhanced formability and smooth surface finishes.

• Ideal for intricate designs and rapid prototyping

• Applications: Decorative ceramics, consumer product prototypes
