Measured mechanical data
950 MPa 4-point bending strength at >5.95 g/cc, 2070 MPa compressive strength and sub-0.5 µm grain — the toughest oxide in the 3DCeram range, backed by datasheet numbers.
The full ceramic workflow
Every order ships with the debinding and sintering parameters. Zirconia is solid-state sintered to >99.5% density, and shrinkage is compensated in build prep so the first part lands on dimension.

About this product
Zirconia 3Y 3D Printing Paste is a 3DCeram 3 mol% yttria-stabilized zirconia paste for the Ceramaker laser-SLA platform — you print a green part, then debind and sinter it to a dense, exceptionally tough oxide ceramic.
Why engineers choose this paste
The toughest of the standard oxides: high strength, fine grain and colourable for aesthetic parts.
950 MPa bending strength
4-point flexural strength at >5.95 g/cc and >99.5% densification — the highest-strength oxide in the range.
Colourable & aesthetic
Fine sub-0.5 µm grain takes colour and polish — used in jewellery, watch cases and visible components.
Biocompatible
Proven in dental and biomedical implants where strength and body compatibility both matter.
2070 MPa compressive
12.6 GPa Vickers hardness and strong wear resistance for high-load precision parts.
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
Solid-state sintered to >99.5% dense zirconia (>5.95 g/cc), sub-0.5 µm grain and 950 MPa bending strength.
Typical applications
Where toughness, fine finish and biocompatibility are the deciding factors.
Jewellery & watches
Colourable, polishable, scratch-resistant parts
Biomedical implants
Dental and orthopaedic components
Electronic equipment
Precision insulating and structural parts
Wear components

Common questions
Don't see yours? Email [email protected] — NDA standard, typical reply within 4 hours.
What is Zirconia 3Y paste and how does it produce a ceramic part?
Zirconia 3Y 3D Printing Paste is a 3DCeram ceramic feedstock — 3 mol% yttria-stabilized zirconia (ZrO₂) powder in a photocurable binder. You print a green part on the Ceramaker laser-SLA platform, then debind and sinter it to a dense oxide ceramic reaching >99.5% densification, >5.95 g/cc and 950 MPa 4-point bending strength. Every order ships with the debind and sinter parameters so the first build reaches target density predictably.
Why does the printed part come out larger than my CAD model?
Ceramic AM prints a green part that is larger than the finished component. During sintering the binder is removed and the particles fuse, so the part shrinks — typically 15–20% linear for zirconia. That shrinkage is predictable and is compensated in build preparation, so your sintered part lands on the target dimensions. We supply the parameters that make it repeatable.
How does zirconia compare with alumina?
Zirconia is much tougher — 950 MPa bending strength versus 397 MPa for alumina — and resists crack propagation far better, so it wins wherever impact, thin walls or high load are involved. Alumina is harder, a better insulator and cheaper. For jewellery, dental and high-strength precision parts, 3Y zirconia is the usual choice. Tell us the load case if you want a recommendation.
Is Zirconia 3Y suitable for medical or dental implants?
3Y zirconia is widely used for dental and orthopaedic components because it combines high strength with biocompatibility. The exact grade, cleanliness and sintering route for an implant application must be qualified for your regulatory pathway — send the requirement and a materials engineer will confirm what the 3DCeram paste and process can support, NDA standard.
Can the parts be coloured?
Yes. One reason 3Y zirconia is popular in jewellery and watchmaking is that it can be coloured and polished to a fine finish, thanks to its sub-0.5 µm grain size. Colouring is done through the material/process rather than a surface coating. Tell us the target colour and finish and we will advise on what is achievable.
Which printer runs this paste, and can I trial it first?
Zirconia 3Y paste runs on 3DCeram Ceramaker laser-SLA machines (C900 FLEX and the Cxxx family) — it is not an FFF filament. We routinely ship a sample or small batch so you can validate rheology, shrinkage and sintered strength on your own hardware before a production order. Ask a materials engineer to scope the trial — NDA standard.
