Abstract
Resins for 3D printing of a preceramic composition loaded with a solid polymer filler, followed by converting the preceramic composition to a 3D-printed ceramic material, are described. Some variations provide a preceramic composition containing a radiation-curable liquid resin formulation and a solid polymer filler dispersed within the liquid resin formulation. The liquid resin formulation is compatible with stereolithography, UV curing, and/or 3D printing. The solid polymer filler may be an organic polymer, an inorganic polymer, or a combination thereof. The solid polymer filler may itself be an inorganic preceramic polymer, which may have the same composition as a polymerized variant of the liquid resin formulation, or a different composition. Many compositions are disclosed as options for the liquid resin formulation and the solid polymer filler.
