Silicore 3D Printing Paste
Print robust, leachable Silicore foundry cores on 3DCeram's Ceramaker laser-SLA platform for complex, demanding castings.
- ✓ Higher-strength silica core formulation — survives handling and assembly
- ✓ Good leachability and low shrinkage (0.20% max to 1500 °C); all alloys except cobalt
- ✓ Ceramic SLA paste for the 3DCeram Ceramaker platform — quote-based, mutual NDA before spec review
What your foundry engineer actually checks
Core-specific data
29% porosity, 15.4 MPa bending strength and 0.20% maximum shrinkage to 1500 °C — the balance of robustness and leachability that decides core performance. We ship the datasheet.
The full ceramic workflow
Every order ships with the firing and handling parameters. Shrinkage is compensated in build prep so printed cores land on dimension and leach out predictably.
A materials engineer on the line
Core printing, firing and leaching are where casting jobs fail. Talk to an engineer who runs this paste — sub-4h reply, NDA standard.
Silicore 3D Printing Paste is a 3DCeram silica-based paste engineered for foundry cores — a porous, leachable ceramic with the mechanical robustness to survive handling and the pour.
Why engineers choose this paste
A foundry-core formulation tuned for strength and leachability on complex core shapes.
Good leachability
Porous silica core removes cleanly after casting, even from complex internal shapes.
Stable at high temperature
Holds up through casting temperatures for reliable core performance.
Mechanically robust
A higher-strength silica core formulation that survives handling and assembly.
Complex core geometry
Print internal passages and cores conventional coremaking cannot produce.
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
Fired to a porous silica core (1.77 g/cc, 29% porosity) with low shrinkage and good leachability.
Typical applications
Foundry cores for complex castings, compatible with most alloys.

- ✓ 11+ ceramic materials — Al₂O₃, ZrO₂, Si₃N₄, TCP, HA, AlN, cordierite and more
- ✓ Top-down SLA — support-free complex internal geometries in dense ceramic
- ✓ SAM option — 100 mL minimum batch for R&D economy with expensive compositions
Automated cleaning system that removes excess ceramic paste from freshly printed green parts, leaving them ready to debind — replacing slow, hands-on solvent cleaning in the ceramic AM workflow.
- ✓ Gentle, low-mechanical-stress cleaning of fragile green parts
- ✓ Batch time cut dramatically vs manual (e.g. 60 min → 5 min on 70 alumina parts)
- ✓ Solvent longevity + recycling · no manual solvent contact
Print leachable fused-silica investment-casting cores on 3DCeram's Ceramaker laser-SLA platform for complex internal casting geometries.
