Aluminium Nitride 3D Printing Paste
Print aluminium nitride (AlN) parts on 3DCeram's Ceramaker laser-SLA platform, then debind and sinter to a ceramic that conducts heat yet insulates electrically.
- ✓ 163 W/m·K thermal conductivity with electrical insulation — power-electronics substrates
- ✓ Print conformal cooling and channelled geometries not possible by pressing
- ✓ Ceramic SLA paste for the 3DCeram Ceramaker platform — quote-based, mutual NDA before spec review
What your process engineer actually checks
Functional thermal data
163.1 W/m·K thermal conductivity with electrical insulation and 368 GPa modulus — the property set that makes AlN a power-electronics ceramic, backed by datasheet numbers.
The full ceramic workflow
Every order ships with the debinding and sintering parameters. AlN is sintered to 97% density, and shrinkage is compensated in build prep so conformal cooling geometries land on dimension.
A materials engineer on the line
Non-oxide sintering, solids loading and shrinkage are unforgiving. Talk to an engineer who runs this paste — sub-4h reply, NDA standard.
Aluminium Nitride 3D Printing Paste is a 3DCeram aluminium nitride (AlN) paste for the Ceramaker laser-SLA platform — a non-oxide ceramic that combines very high thermal conductivity with electrical insulation.
Why engineers choose this paste
The go-to ceramic for power electronics: it conducts heat like a metal but insulates like a ceramic.
163 W/m·K thermal conductivity
Moves heat far better than alumina while staying an electrical insulator — ideal for power-electronics substrates.
Electrical insulation
High resistivity for insulating heat-spreader and substrate roles in electronics.
368 GPa modulus
High stiffness and good mechanical strength at 3.22 g/cc density.
Complex SLA geometry
Print channelled and conformal cooling geometries not practical by pressing.
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
Sintered to 97% dense AlN (3.22 g/cc, <5 µm grain) preserving high thermal conductivity.
Typical applications
Thermal-management and insulating parts for electronics.
