What we print
Geometry that a tool cannot reach.
Cores, lattices and channels that would otherwise need a mould, a five axis mill or a small miracle. We print the green part, remove the binder, then sinter it dense.
Casting cores
Internal cooling channels and thin walled cores for single crystal blades, then leached out after casting.
Silica based CoreCera SC
Filtration and flow
Honeycomb and gyroid structures with channel walls down to 100 µm, held uniform across the whole cross section.
Alumina and zirconia
Electronics and thermal
Alumina and zirconia for high voltage insulation, aluminium nitride for heat that has to leave the part, with vias and standoffs printed in the same build.
See applications
Medical and dental
Zirconia abutments and porous bone scaffolds built from patient geometry, with controlled pore size and strut thickness.
Biocompatible zirconiaFour steps, one logged parameter set.
Additive is only the first third of the job. The parts that fail usually fail in debinding or in the furnace, so that is where we spend our attention.
1
Cure the slurry
A 460 nm DLP engine exposes each layer through a transparent vat while a blade re-coats ceramic loaded slurry.
2
Remove the binder
Organics come off on a controlled ramp so the green part does not crack before it ever reaches the furnace.
3
Densify the ceramic
The part shrinks as it densifies. We model that compensation into the build file, geometry by geometry.
4
Measure the result
Optical metrology and CT scanning confirm wall thickness and internal channels before anything ships out.
Materials
Three workhorses, eight qualified grades.
Oxide grades we run every week, plus non-oxide grades for heat, thermal shock and wear. Every figure below is measured on printed and sintered test bodies, not borrowed from a pressed and machined data sheet.

Ceramic additive manufacturing fails at the margins. Thin walls crack in debinding, shrinkage opens up tolerances, and one bad furnace cycle can undo a week of printing. Every step below is logged against your order number.
Shrinkage modelled per geometry
15 to 20% linear, applied in the build file and checked against the first article.
First article report
A dimensional report ships with every new geometry, before the batch runs.
Batch traceability
Powder lot, slurry batch and furnace cycle recorded against each order.
Optical and CT metrology
Wall thickness and internal channels verified, not estimated.
