What your process engineer actually checks
Measured mechanical data
397 MPa 4-point bending strength at >3.9 g/cc density, 300 GPa modulus and 16.4 GPa Vickers hardness — datasheet numbers you can qualify against, not a vendor estimate.
The full ceramic workflow
Every order ships with the debinding and sintering parameters. Alumina is solid-state sintered, 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 3D Printing Paste is a 3DCeram alumina (Al₂O₃) paste for the Ceramaker laser-SLA platform — you print a green part, then debind and sinter it to a dense, hard, electrically insulating oxide ceramic.
Why engineers choose this paste
A workhorse technical oxide: hard, wear-resistant and a proven electrical insulator at temperature.
397 MPa bending strength
4-point flexural strength at >3.9 g/cc density after sintering — a dependable structural oxide.
High electrical resistivity
Insulates at temperature with 23.3 W/m·K thermal conductivity — the standard choice for electronic and telecom parts.
16.4 GPa Vickers hardness
High hardness and good wear resistance for jigs, guides and abrasion-exposed components.
Chemically inert
Resists most acids, bases and molten media — suited to lab and process-hardware duty.
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 dense alumina (>3.9 g/cc), ~2.2 µm grain size and 300 GPa modulus.
Typical applications
Where hardness, insulation and chemical inertness matter more than toughness.
