DESCRIPTION:Dr. Angkur Shaikeea\, Department of Engineering\, University o
 f Cambridge\nAbstract: Additive manufacturing represents one of the most s
 ustainable means of production at various frontiers\, from elimination of 
 excess materials to design of complex geometries. While rapid progress has
  taken place in improving as a manufacturing technology\, there are variou
 s bottlenecks for its translation from laboratory to industry especially i
 n scalability and high throughput production. Issues like geometric and ma
 terial imperfections that result in deviation of performance from design p
 rediction\, are yet to be addressed. Using micro-stereolithography\, archi
 tected solids are printed with millions of unit cells to create macro size
 d specimens and continuum theories for failure are testified. The exercise
  led to development of innovative non-destructive characterisation techniq
 ues\, the necessity of in-situ experiments in testing (like Digital Volume
  Correlation) and a revision of 50 years old theories in elastic fracture 
 mechanics. It also opens up opportunities for a new paradigm in design and
  fabrication of additive manufacturing where large experimental data can b
 e incorporated (to account for imperfections\, etc.) using deep-learning m
 odels. We are in an exciting era when the importance of environment is str
 ongly imbibed in materials and mechanical engineering. A range of innovati
 ve experiments and new design philosophies can be key to proliferation of 
 sustainable manufacturing.\n\nBiography: Angkur Shaikeea is presently the 
 Ashby Postdoctoral Research Fellow in the Department of Engineering where 
 he had previously completed his PhD as the Ramanujan Scholar. His present 
 research focusses on understanding imperfections in additive manufacturing
  using non-destructive techniques and in-situ experiments with lab-based X
 -ray CT. His doctoral research involved large scale computations coupled w
 ith experiments which resulted in proposing design maps for failure resili
 ent mechanical metamaterials. He has close collaborations with both indust
 ry and university\, and strongly believes in interdisciplinary collaborati
 ve research.
