Indentation fracture of 3D printed silicon nitride

Key Points

• Indentation fracture in 3D printed silicon nitride indicates significant loss of structural integrity when subjected to stress.
• The study shows a fracture strength of approximately 300 MPa in this material, providing a benchmark for future applications.
• Assessment using mechanical testing highlighted varied failure modes, demonstrating complexity in the material's behavior under load.
• Findings may enable improved design strategies in ceramics, though further investigation in diverse environments is crucial.
