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.
A preceramic composition containing (a) a UV-curable inorganic liquid resin formulation, (b) a solid polymer filler dispersed within said UV-curable inorganic liquid resin formulation, and (c) a photoinitiator, wherein said UV-curable inorganic liquid resin formulation is capable of being polymerized when exposed to said photoinitiator and electromagnetic radiation wavelengths selected from 200 nm to 700 nm, wherein said solid polymer filler is selected from the group consisting of poly(carbosilanes), poly(silazanes), poly(silsesquioxanes), poly(borosiloxanes), poly(borosilanes), poly(borosilazanes), poly(carbosiloxanes), poly(silylcarboimides), poly(silsesquicarbodiimides), polyborazines, and combination thereof.
A preceramic composition containing (a) a UV-curable inorganic liquid resin formulation, (b) a solid polymer filler dispersed within said UV-curable inorganic liquid resin formulation, and (c) a photoinitiator, wherein said UV-curable inorganic liquid resin formulation is capable of being polymerized when exposed to said photoinitiator and electromagnetic radiation wavelengths selected from 200 nm to 700 nm, wherein said solid polymer filler is itself an inorganic preceramic polymer that has the same composition as a polymer of said UV-curable inorganic liquid resin formulation.
A preceramic composition containing (a) a UV-curable inorganic liquid resin formulation, (b) a solid polymer filler dispersed within said UV-curable inorganic liquid resin formulation, and (c) a photoinitiator, wherein said UV-curable inorganic liquid resin formulation is capable of being polymerized when exposed to said photoinitiator and electromagnetic radiation wavelengths selected from 200 nm to 700 nm, wherein said solid polymer filler is a boron-based polymer.
