Abstract:
Compared to metals and polymers, the incorporation of ceramics into the framework of Industry 4.0 has been lagged due to the inherent problems in the processing of ceramics. Here, I will present a work flow to adapt ceramics to digital processing schemes. Our design is based on green machining where the weakly-bound ceramic powder is shaped instead of the pre-sintered or sintered hard bodies that are prone to cracking, require higher machining forces, and lead to tool wear. First, I will discuss the preparation of green bodies from ceramic doughs that can be manipulated by hand, cut, or pushed into a mold. This facile method relies on a single 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 triangle 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-, thus cost-saving approach will transform how we process ceramics.
