Alumina Toughened Zirconia 3D Printing Paste
Print the strongest oxide in the range — alumina-toughened zirconia — on 3DCeram's Ceramaker laser-SLA platform, then debind and sinter to a dense biocompatible ceramic.
- ✓ 1094 MPa 4-point bending strength at >5.2 g/cc — highest of the 3DCeram oxides
- ✓ Biocompatible and thermal-shock resistant — implants, dental and high-load wear parts
- ✓ Ceramic SLA paste for the 3DCeram Ceramaker platform — quote-based, mutual NDA before spec review
What your process engineer actually checks
Measured mechanical data
1094 MPa 4-point bending strength at >5.2 g/cc and sub-0.5 µm grain — the highest-strength oxide in the 3DCeram range, backed by datasheet numbers rather than a vendor estimate.
The full ceramic workflow
Every order ships with the debinding and sintering parameters. ATZ is solid-state sintered to >99% density, and shrinkage is compensated in build prep so the first part lands on dimension.
A materials engineer on the line
Solids loading, rheology, shrinkage and cracking are where ceramic AM fails. Talk to an engineer who runs this paste — sub-4h reply, NDA standard.
Alumina Toughened Zirconia 3D Printing Paste is a 3DCeram alumina-toughened zirconia paste for the Ceramaker laser-SLA platform — an 80% zirconia / 20% alumina blend that pairs high strength with biocompatibility and thermal-shock resistance.
Why engineers choose this paste
A composite oxide tuned for the highest bending strength in the range with biomedical-grade compatibility.
1094 MPa bending strength
The highest 4-point flexural strength of the 3DCeram oxides — zirconia toughness reinforced by alumina hardness.
Biocompatible
Used in implants and dental parts where wear resistance and body compatibility both matter.
Thermal-shock resistant
Withstands rapid temperature change better than single-phase oxides.
220 GPa modulus
High stiffness and hardness at >5.2 g/cc density and sub-0.5 µm grain.
Print → debind → sinter
Ceramic stereolithography on the 3DCeram Ceramaker platform. The green part is larger than the finished part — shrinkage is compensated in build preparation.
Laser SLA print
The ceramic-loaded paste is cured layer-by-layer on a 3DCeram Ceramaker laser-SLA machine into a green part.
Debinding
The organic binder is removed in a controlled thermal cycle, leaving a fragile ceramic-only brown part.
Sintering
Solid-state sintered to >99% dense ATZ (>5.2 g/cc), sub-0.5 µm grain and 1094 MPa bending strength.
Typical applications
High-load and biomedical parts that need both strength and durability.
ATZ — physical & mechanical properties
