General description

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Green Chemistry. This product has been enhanced for energy efficiency. Click here for more information.


This product can be used in material extrusion 3D printing technique.
This product is a thixotropic ink based on yttria stabilized zirconia (YSZ) nanoparticles. It is suitable for various direct ink write (aka robocasting) printing technologies . Our YSZ ink has also been validated for stereolithography (SLA) 3D printing. The ink offers a stable dispersion of YSZ, high viscosity, good printability, and long shelf life. Annealed patterns provide excellent chemical resistance and high surface area. The ink is suitable for applications such as membranes, catalysis, separators and reactors.


Handeling tips:
  • Store in an airtight sealed container in refrigerator.
  • Avoid exposure to heat.
  • Add the thermal initiator (product No.479896) to 0.3wt% of the total 3Y-ZrO2/PEGDA ink mass, and mix well before usage.

Preparation Note

Step-by-Step procedure for ink mixing and loading into syringe is in attached file.

Direct-Ink-Writing (DIW) Notes:
  • Syringe Nozzle sizes ranging from 250 μm − 800 μm can be used.
  • Initial pressure for DIW printing ranges from 12-18 psi, depending on nozzle diameter used.

Post Processing of DIW printed parts:
  • Curing @ 110°C for 12-16 hours.
  • Sintering using the following sequence:
Starting at RT, Ramp to 200°C for 6 hours.
Ramp to 300°C @ 1°C/min. Hold for 4 hours.
Ramp to 400°C @ 1°C/min. Hold for 2 hours.
Ramp to 800°C @ 2°C/min. Hold for 4 hours.
Ramp to 1090°C @ 2°C/min. Hold for 15 hours.
Ramp down to 50°C @ 2°C/min.

Storage and Stability

Tighly seal remaining ink, and store in 2-8° C fridge.
