 I am Reza Moini, I'm pursuing my PhD in civil engineering at Purdue University. 3D printing allows you to incorporate various design concepts and so therefore it allows you to fabricate elements with a specific architecture. However, one weakness is that layer by layer printing process typically involves formation of internal flaws and non-uniformities in the microstructure of the material. What's novel about our work is that using 3D printing we incorporate bio-inspired architectures that provide resilience, flaw-tolerant and fracture resistance to a material that's intrinsically brittle. We've looked into a variety of design and architecture such as compliant design, honeycomb architecture, or exotic architecture, which are specifically bulletin architectures. These architectures can bring in specific performance characteristics and enhance the properties without sacrificing the strength compared to conventionally cast cement-based materials. Given the direction that the 3D printing technology is taking, I hope we can learn from these architectures and look into new ways of designing the materials and structures for future.
