摘要： In an example of a three-dimensional (3D) printing method, a ceramic build material is applied. A detailing agent fluid is applied to a portion of the ceramic build material. The detailing agent fluid includes a cationic polymer. A liquid functional material, including an anionically stabilized susceptor material, is applied to another portion of the ceramic build material that is in contact with the portion of the ceramic build material having the detailing agent fluid thereon, such that at least some of the anionically stabilized susceptor material reacts with at least some of the cationic polymer that is in contact therewith to prevent spreading of the anionically stabilized susceptor material.

摘要： This invention provides resin formulations which may be used for 3D printing and pyrolyzing to produce a ceramic matrix composite. The resin formulations contain a solid-phase filler, to provide high thermal stability and mechanical strength (e.g., fracture toughness) in the final ceramic material. The invention provides direct, free-form 3D printing of a preceramic polymer loaded with a solid-phase filler, followed by converting the preceramic polymer to a 3D-printed ceramic matrix composite with potentially complex 3D shapes or in the form of large parts. Other variations provide active solid-phase functional additives as solid-phase fillers, to perform or enhance at least one chemical, physical, mechanical, or electrical function within the ceramic structure as it is being formed as well as in the final structure. Solid-phase functional additives actively improve the final ceramic structure through one or more changes actively induced by the additives during pyrolysis or other thermal treatment.
