What your process engineer actually checks
Measured mechanical data
881 MPa 4-point bending strength at >3.13 g/cc with an 11 Weibull modulus and low CTE — the property set behind its thermal-shock and wear performance, backed by datasheet numbers.
The full ceramic workflow
Every order ships with the debinding and sintering parameters. Silicon nitride is sintered to >97% density, and shrinkage is compensated in build prep so the first part lands 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 on request.
Silicon Nitride 3D Printing Paste is a 3DCeram silicon nitride (Si₃N₄) paste for the Ceramaker laser-SLA platform — one of the hardest, most thermal-shock-resistant technical ceramics available.
Why engineers choose this paste
A premium non-oxide for the harshest duty: high strength, thermal-shock resistance and low wettability against molten metal.
881 MPa bending strength
High 4-point flexural strength at >3.13 g/cc with an 11 Weibull modulus — consistent, dependable strength.
Thermal-shock resistant
Low CTE (1.23 ×10⁻⁶/K) and high strength let it survive rapid temperature change.
Low wettability to molten metal
Resists corrosion by liquid and gaseous media — ideal for metal-handling components.
290 GPa modulus
High stiffness and wear resistance for pumps, valves and semiconductor hardware.
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 silicon nitride (>3.13 g/cc, <2.5% open porosity) with 881 MPa bending strength.
Typical applications
Wear, thermal-shock and corrosion-critical components.
