Additive Manufacturing 3D Printing of Advanced Ceramics
20170008236 · 2017-01-12 ·

Methods, processes, systems, devices and apparatus are provided for additive manufacture resulting in the 3D printing of novel ceramic composites. Additive manufacture or 3D printing of bulk ceramic and ceramic composite components occurs at considerably lower temperatures and shorter manufacturing intervals than the current state of the art. The methods, processes, systems, devices and apparatus and selection of precursor resins produce ceramic and ceramic composite material systems which have not been produced before by 3D printing.

Composite Ceramics and Ceramic Particles and Method for Producing Ceramic Particles and Bulk Ceramic Particles
20170001915 · 2017-01-05 ·

Methods for producing Polymer Derived Ceramic (PDCs) particles and bulk ceramic components and compositions from partially cured gelatinous polymer ceramic precursors and unique bulk composite PDC ceramics and unique PDC ceramic particles in size and composition. Methods of making fully dense PDCs over approximately 2 m to approximately 300 mm in diameter for applications such as but not limited to proppants, hybrid ball bearings, catalysts, and the like. Methods can include emulsion processes or spray processes to produce PDCs. The ceramic particles and compositions can be shaped and chemically and materially augmented with enhancement particles in the liquid resin or gelatinous polymeric state before being pyrolyzed into ceramic components. The resulting ceramic components have a very smooth surface and are fully dense, not porous as ceramic components from the sol-gel process.
