What your regulatory engineer actually checks
Purity and phase data
Crystallinity >95%, Ca/P ratio 1.65–1.82, foreign phases ≥5% and heavy metals <30 ppm — the composition data an implant material must be qualified against. We ship the datasheet.
The full ceramic workflow
Every order ships with the debinding and sintering parameters. Hydroxyapatite is sintered to >96% density, and shrinkage is compensated in build prep so patient-specific geometries land on dimension.

Hydroxyapatite 3D Printing Paste is a 3DCeram hydroxyapatite paste for the Ceramaker laser-SLA platform — a bioactive calcium-phosphate ceramic whose composition is close to natural bone.
Why engineers choose this paste
A bioceramic for bone-substitute and implant work: bioactive, osseointegrating and clean.
Bioactive & osseointegrating
Composition close to bone mineral encourages bone in-growth in orthopaedic and cranial implants.
Controlled purity
Crystallinity >95%, foreign phases ≤5% and heavy metals <30 ppm — specified for biomedical use.
Patient-specific geometry
Print porous, patient-matched implant geometries not possible by machining.
107 MPa bending strength
Sintered structural strength for bone-substitute components.
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 >96% dense hydroxyapatite (>1.5 g/cc, ~2 µm grain) with crystallinity above 95%.
Typical applications
Orthopaedic and cranial bone-substitute implants.
Hydroxyapatite — physical & biomedical properties
Representative post-sinter values from the 3DCeram material datasheet. Final numbers depend on part geometry and your qualified sinter cycle. Debinding and shrinkage data are provided for guidance only; print presets are not included — you tune the sinter cycle on your own equipment.

Complete the workflow
- ✓ 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 bioresorbable tricalcium phosphate (TCP) scaffolds on 3DCeram's Ceramaker laser-SLA platform, then debind and sinter to a clean, resorbable bioceramic.
