What your process engineer actually checks
The property that matters
A CTE near zero (-0.10 ×10⁻⁶/K at 20 °C) is why cordierite exists in this range — dimensional stability, not raw strength. We ship the datasheet so you qualify against that number.
The full ceramic workflow
Every order ships with the debinding and sintering parameters. Cordierite is solid-state sintered to >98% density, and shrinkage is compensated in build prep so the first part lands on dimension.
A materials engineer on the line
Solids loading, shrinkage and cracking are where ceramic AM fails. Talk to an engineer who runs this paste — sub-4h reply, NDA standard.
Cordierite 3D Printing Paste is a 3DCeram cordierite paste for the Ceramaker laser-SLA platform — a near-zero-expansion oxide ceramic prized for dimensional stability under thermal cycling.
Why engineers choose this paste
Chosen for one property above all: it barely moves when temperature changes.
Near-zero CTE
Coefficient of thermal expansion close to zero (-0.10 ×10⁻⁶/K at 20 °C) — dimensionally stable through thermal cycling.
Low thermal conductivity
3.8 W/m·K — insulates and resists thermal shock.
Wear resistant
Durable oxide surface for metrology and optical mounting hardware.
Vacuum-compatible
Stable, low-outgassing ceramic suited to vacuum applications.
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 >98% dense cordierite (>2.5 g/cc, ~0.89 µm grain) with near-zero expansion.
Typical applications
Where a part must hold its dimensions through temperature change.
