| Abstract Scope |
Over the last several years, considerable progress has been made in additive manufacturing (AM) technologies and the materials available for such technologies. Material extrusion, in particular, provides unique opportunities for AM of composite materials with high solids loading, unique multi-scale architecture and fiber arrangement. This approach has been studied in some depth using thermoplastic and thermoset polymers, but there is growing interest in utilizing preceramic polymers with material extrusion to enable AM of ceramic composites. This talk will begin with a brief overview of material extrusion AM, followed by a discussion of features of the process that are relevant to controlling architecture and properties in printed composites. The talk will conclude with the discussion of a few examples of material extrusion AM of high- and ultra-high temperature ceramics using highly-loaded silicon carbide and silicon nitride precursor polymers. Additional challenges associated with pyrolysis of the preceramic polymers will also be discussed. |
