Abstract: Methods, processes, systems, devices and apparatus are provided for additive manufacture resulting in the 3D printing of ceramic materials and components with a thickness greater than three millimeters (3 mm). A sulfur-free 3D printable formulation comprises a liquid inorganic polymer resin using Stereolithograpy (SLA) printers and Digital Light Processing (DLP) curing of the polymer resin via the chemical bonding of the materials rather than sintering. Thus, the process has shorter manufacturing intervals, significantly lower energy use and produces larger scale ceramic components having less linear shrinkage, less mass loss and high ceramic yield with no corrosive sulfur compounds present in the ceramic component.

Abstract: A composite article is comprised of coal dust, as defined herein, and a polymer derived ceramic material that is pyrolyzed in a substantially non-oxidizing atmosphere. For example, the composite article may be made of a mixture of the coal dust and polymer derived ceramic, from particles formed of a mixture of coal dust and polymer derived ceramic or from complex particle composites comprising a plurality of particles formed of a mixture of coal dust and polymer derived ceramic.

Abstract: Methods, systems, and processes are used to prepare novel ceramic composite structures that are strong, durable, light-weight, high performance and suitable for a myriad of industrial applications, including, but not limited to, ceramic plates of material suitable for use as ballistic armor. The low manufacturing costs of the processes disclosed provide cheaper, faster ways of producing ceramic matrix composites at lower temperatures and allow for the existence of composite materials and structures which currently are not available.

Abstract: A composite tile is comprised of coal dust and a pre-ceramic polymer that are mixed together and pyrolyzed to form a ceramic composite. For example, a chemical reaction during pyrolysis chemically converts at least a portion of the coal dust and pre-ceramic polymer to a fire proof ceramic composite suitable for use as a roofing tile either as pyrolyzed or as post-treated to seal cracks and pores formed during pyrolysis.

Abstract: A complex ceramic particle and ceramic composite material may be made of a pretreated coal dust and a polymer derived ceramic that is mixed together and pyrolyzed in a nonoxidizing atmosphere. Constituent portions of the particle mixture chemically react causing particles to increase in density and reduce in size during pyrolyzation, yielding a particle suitable for a plurality of uses including composite articles and proppants.

Abstract: 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.
