What your regulatory engineer actually checks
What your regulatory engineer actually checks
Purity and phase data
Ca/P ratio 1.503, hydroxyapatite content held to 0–5% and no calcium pyrophosphate — the composition data a resorbable implant material must be qualified against. We ship the datasheet.
The full ceramic workflow
Every order ships with the debinding and sintering parameters. Shrinkage is compensated in build prep so patient-specific scaffold geometries land on dimension.

About this product
Tricalcium Phosphate 3D Printing Paste is a 3DCeram tricalcium phosphate (TCP) paste for the Ceramaker laser-SLA platform — a bioresorbable calcium-phosphate ceramic that is gradually replaced by natural bone.
Why engineers choose this paste
A resorbable bioceramic for implants that are meant to be replaced by the patient’s own bone.
Bioresorbable
Gradually dissolves and is replaced by natural bone — ideal for temporary scaffolds and bone regeneration.
Biocompatible
Calcium-phosphate composition close to bone mineral, with controlled Ca/P ratio of 1.503.
Patient-specific geometry
Print porous, patient-matched scaffolds that support bone in-growth.
Controlled phase purity
No calcium pyrophosphate, hydroxyapatite content held between 0–5%.
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.
Step 01
Laser SLA print
The ceramic-loaded paste is cured layer-by-layer on a 3DCeram Ceramaker laser-SLA machine into a green part.
Step 02
Debinding
The organic binder is removed in a controlled thermal cycle, leaving a fragile ceramic-only brown part.
Step 03
Sintering
Sintered to ~81% dense TCP (2.47 g/cc, ~2.8 µm grain) with a controlled Ca/P ratio and phase purity.
Typical applications
Resorbable bone-substitute and spinal implants.
Bone substitutes
Resorbable osseous scaffolds
Spinal implants
Structures matched to spine anatomy

Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
What is Tricalcium Phosphate and why use it?
Tricalcium Phosphate (TCP) is a calcium-phosphate bioceramic that is bioresorbable — once implanted, it is gradually dissolved and replaced by the patient's own bone. That makes it ideal for temporary scaffolds and bone-regeneration implants, especially in the spine. You print a green part on the Ceramaker laser-SLA platform, then debind and sinter it to a controlled-purity TCP component.
How does TCP differ from hydroxyapatite?
Both are calcium-phosphate bioceramics, but TCP is resorbable — it is replaced by bone over time — while hydroxyapatite is more stable and stays in place, osseointegrating. You choose TCP when you want the implant to be gradually replaced by natural bone, and hydroxyapatite for a durable substitute. Many implants blend the two. Tell us the clinical goal and a materials engineer will advise.
How is the material qualified for biomedical use?
The datasheet specifies the composition data that matters for a resorbable implant: Ca/P ratio 1.503, hydroxyapatite content held to 0–5%, and no calcium pyrophosphate detected. Final device qualification is your regulatory responsibility, but we supply the composition and process parameters. Send your pathway and a materials engineer will confirm what is supported — NDA standard.
Can I print porous or patient-specific scaffolds?
Yes — that is a key reason to use ceramic SLA for resorbable implants. You can build controlled porosity and patient-matched geometry that supports bone in-growth as the TCP resorbs. Send the anatomy or CAD and a materials engineer will confirm what the process supports.
Why does the printed part shrink during processing?
TCP prints as an oversized green part; the binder is removed in debinding and the ceramic consolidates in sintering, so the part shrinks to final size. Shrinkage is predictable and compensated in build preparation, so the sintered scaffold lands on the target dimensions. We supply the parameters that make it repeatable.
Which printer runs this paste, and can I trial it?
TCP paste runs on 3DCeram Ceramaker laser-SLA machines. It is not an FFF filament. We routinely ship a sample or small batch so you can validate density, purity and geometry on your own hardware before a production order. Talk to a materials engineer to scope the trial — NDA standard.
