Abstract Scope |
Since the last two decades, additive manufacturing (AM) has transformed the landscape of engineering manufacturing towards the delivery of ‘on demand’ structural complexity with a minimal compromise in the end properties. Binderjet printing is one of the most promising AM techniques in ‘regenerative engineering’ to fabricate biomedical prosthesis and scaffolds with the host tissue mimicking properties. In this talk, the scope of the 3D binderjetting of zirconia based bioceramics will be discussed along with the long persisting challenges. ‘Printability’ of powder, flowability, cohesive bed packing are few examples of such challenging aspects. Additionally, some of the commercial binderjet printers print the layers in a ‘default core-shell’ manner which is detrimental in load bearing orthopedic applications. This talk will address the limitations for the first time in the literature, along with a spectrum of strategic troubleshooting methodologies to achieve complex zirconia-based architectures having consistent microstructure and biomedically relevant strength properties. |
