摘要: This disclosure provides resin formulations which may be used for 3D printing and thermally treating to produce a ceramic material. The disclosure provides direct, free-form 3D printing of a preceramic polymer, followed by converting the preceramic polymer to a 3D-printed ceramic composite with potentially complex 3D shapes. A wide variety of chemical compositions is disclosed, and several experimental examples are included to demonstrate reduction to practice. For example, preceramic resin formulations may contain a carbosilane in which there is at least one functional group selected from vinyl, allyl, ethynyl, unsubstituted or substituted alkyl, ester group, amine, hydroxyl, vinyl ether, vinyl ester, glycidyl, glycidyl ether, vinyl glycidyl ether, vinyl amide, vinyl triazine, vinyl isocyanurate, acrylate, methacrylate, alkyl acrylate, alkyl methacrylate, phenyl, halide, thiol, cyano, cyanate, or thiocyanate. The resin formulations may contain a solid-phase filler, to provide high thermal stability and mechanical strength (e.g., fracture toughness) in the final ceramic material.

摘要: A green body for a 3D ceramic and/or metallic body is produced by providing a metal or a mixture of metals and/or a metalloid and/or a non-metal or mixtures thereof in form of at least one aqueous solutions, such as a metal nitrate solution; if more than one aqueous solutions are provided, they differ in composition and/or isotope concentration. One aqueous metal solution is mixed with a gelation fluid at a first temperature to suppress an internal gelation of the feed solution mixture prior to its ejection. The feed solution mixture is ejected by inkjet printing to the green body under construction. The ejected feed solution is heated mixture on the green body to a second temperature to fix it on the green body under construction. Several process steps are repeated according to a 3D production control model until a desired form of the green body is attained.

摘要: An integrated polymer-derived ceramic (PDC) thin-film sensor produced by laser pyrolysis and additive manufacturing and a fabrication method thereof are provided. Using a metal component or an insulating material as a substrate, a PDC-doped composite insulating film layer with high density, high insulation, and high temperature resistance is formed by a layer-by-layer laser pyrolysis and additive manufacturing on the surface of the metal component, and a strain sensitive layer with excellent electrical conductivity is obtained by Weissenberg direct writing process PDC-doped filler sensitive grid on the composite insulating film layer and laser pyrolysis enhancing graphitization of PDC. In this way, the in situ integrated laser fabrication of highly insulating film layer, sensitive grid with excellent electrical conductivity, and metal substrate based on PDC materials is developed, which achieves the laser processing of “liquid-solid-function” transformation of PDC composites and allows the successful use thereof in strain sensing of metallic materials.
