DESCRIPTION:Professor Ozge Akbulut\, Sabancı University\, Istanbul\n\nAb
 stract:\nCompared to metals and polymers\, the incorporation of ceramics i
 nto the framework of Industry 4.0 has been lagged due to the inherent prob
 lems in the processing of ceramics. Here\, I will present a work flow to a
 dapt ceramics to digital processing schemes. Our design is based on green 
 machining where the weakly-bound ceramic powder is shaped instead of the p
 re-sintered or sintered hard bodies that are prone to cracking\, require h
 igher machining forces\, and lead to tool wear. First\, I will discuss the
  preparation of green bodies from ceramic doughs that can be manipulated b
 y hand\, cut\, or pushed into a mold. This facile method relies on a singl
 e additive─a linear copolymer─to homogeneously coagulate highly loaded
  ceramic suspensions through polymer bridging. Second\, I will present the
  laser-machining results for the fabrication of intricate shapes such as t
 riangle and hexagonal cavities in yttria-stabilized zirconia and magnesia.
  Lastly\, I will discuss the reuse of the powders to ensure “no material
  leak” in the system. We believe this benchtop\, time- and energy-\, thu
 s cost-saving approach will transform how we process ceramics.\n\nGraphica
 l Abstract:\n\n\n\nShort Bio: : Ozge Akbulut is an Associate Professor at 
 Sabancı University\, Istanbul. She received her B.S. in Materials Scienc
 e and Engineering at Sabancı University in 2004. Her PhD from Massachuset
 ts Institute of Technology (2009) focused on the cost-effective fabricatio
 n of biomolecular devices and surface science. She continued her studies a
 s a post-doctoral fellow at Harvard University\, (2009–2011) on developi
 ng tools/techniques for resource-limited settings. Her main research inter
 ests are the near-net fabrication of ceramics (both additive and subtracti
 ve) and silicone-based composites. She also co-founded a company\, Surgita
 te\, on the design and fabrication of tactile surgical training platforms\
 , in 2014.\n
