3D printed zirconia and alumina

3D printed zirconia and alumina

3D printed zirconia and alumina parts? It has been possible for sometime for engineers and designers to create complex shapes and parts with fine details and utilise a 3D printer to manufacture them. Previously, there where greater restrictions on what could be manufactured with traditional forming processes. There have also been a lack of suitable hard-wearing materials for use on a 3D printer. However, now an engineer can create a CAD file, then easily 3D printed in ceramic materials. As with all ceramics; Zirconia and Alumina have fabulous material properties that are resistant to heat, chemical, electrical and physical wear.

3D printed zirconia and alumina and moreover ceramic materials in general are available on all of our printers from an entry level desk top printer to one that can produce complex geometries in production volumes.

Material Properties

Ceramic 3D printing can use the same materials used in conventional process. So you will see it is possible to have 3D printed zirconia and alumina other ceramics like silicon nitride and others share similar properties which are found in other materials. Ceramics have the following properties;

  • Good mechanical strength
  • High hardness
  • Resistance to thermal shock
  • Very resistance to wear
  • Good electrical insulation
  • Resistant to corrosion; liquids, gas and abrasion
  • Biocompatible

Applications

There are a great number of applications for 3D printed zirconia and alumina. Firstly, typical applications include, aerospace, aviation, investment casting, electronic, optical, medical and luxury markets. Secondly and most controversially, ceramic materials should replace many parts made of metal. Certainly, we believe it is likely these applications would benefit from the material properties of technical ceramics. In short, if you would like to discuss a project where the material properties of ceramic could help please get in touch.

When scientific research focuses on 3D printed zirconia and alumina

As we know 3D printing offers so many opportunities for product development. And so it has become a flourishing field for research. Here, our purpose is to give you the opportunity to read these scientific articles regarding 3d printing, stereolithography, technical ceramics and all kind of applications.

Building parts with an optimized design allows more efficiency in their applications. A 3D printed part allows more compact assemblies with a better optimal integration targeting a significant reduction in the total mass. Indeed, there are many examples of this practise in the field of aeronautics.

Thermo-mechanical properties of 3D printed ceramic parts.

As such, the tool of choice for precise parts made of ceramic is laser Stereolithography (SLA) due to the accuracy and repeatability. To provide weight to this fact this study provides details on the stability of the thermo-mechanical properties of 3D printed ceramic parts. As a short summary; to conduct this study three-dimensional parts were printed then mechanically tested to obtain tensile strengths (<1000MPa) and good hardness (>13 GPa) demonstrate excellent results. Impressively a densification measure was at 98% after sintering.

Anticipating alumina’s’ mechanical and thermal properties.

Another area of significant and interesting research evaluated the elastic and thermal properties of SLA 3D printed alumina. Users of 3DCeram’s alumina formulation developed several simulation models to anticipate its mechanical and thermal properties. The outcome proposes a predictive model that accounts for variation of the microstructure during the manufacturing process and validates the results to be predictable and repeatable. Full details of the study are available through this link.

Structural anisotropy of 3D printed parts

Structural anisotropy of 3D printed parts is a key consideration. The purpose of this study is to acknowledge the affect of varying build direction of parts printed in zirconia.

3D Matters have searched the market for the best fully functional and proven capable technologies. It is for this reason that we are proud to work with the leading manufacturers of Additive Manufacturing equipment and as a result partner with 3D Ceram and Nanoe.

In conclusion, we specialise in the design, printing and post processing of head wearing materials including ceramic and metals. Could 3D printed zirconia and alumina be an advantage to your next project? We often have webinars planned so that we can share and demonstrate more about the technology.
