What your foundry engineer actually checks
Core-specific data
40% porosity, 0.07% maximum dilatation to 1500 °C and controlled shrinkage — the numbers that decide whether a core survives the pour and leaches out cleanly. 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.
Fused Silica 3D Printing Paste is a 3DCeram fused-silica paste for the Ceramaker laser-SLA platform — a porous, easily-leachable silica ceramic developed for investment-casting cores.
Why engineers choose this paste
Built for foundry cores: printable, leachable and dimensionally stable at casting temperature.
Excellent leachability
Porous silica core dissolves out cleanly after casting — even from complex internal passages.
Very low expansion
Maximum dilatation 0.07% up to 1500 °C — holds core dimension through the pour.
Complex core geometry
Print internal cooling passages and cores that cannot be made by conventional coremaking.
High-temperature stable
Low cristobalite content keeps the core stable to casting temperature.
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 (1.36 g/cc, 40% porosity) with shrinkage below 5% and excellent leachability.
Typical applications
Investment-casting cores for complex internal geometries.
