Abstract
The present disclosure relates to systems, methods and resins for additive manufacturing. In one embodiment, a method for additive manufacturing of a ceramic structure includes providing a resin including a preceramic polymer and inorganic ceramic filler particles dispersed in the preceramic polymer. The preceramic polymer is configured to convert to a ceramic phase. The method includes functionalizing inorganic ceramic filler particles with a reactive group and applying an energy source to the resin to create at least one layer of the ceramic phase from the resin.

A method for additive manufacturing of a ceramic structure, the method comprising:
- providing a resin, the resin including a preceramic polymer and inorganic ceramic filler particles dispersed in the preceramic polymer,
- wherein the preceramic polymer is configured to convert to a ceramic phase, and
- wherein the inorganic ceramic filler particles are functionalized with a reactive group and configured to convert to the ceramic phase;
- and
- applying an energy source to the resin to create at least one layer of the ceramic phase from the resin.
A system for resin based additive manufacturing of ceramics, the system comprising:
- a bath configured to contain a resin, the resin including a preceramic polymer and inorganic ceramic filler particles dispersed in the preceramic polymer,
- wherein the preceramic polymer is configured to convert to a ceramic phase,
- wherein the inorganic ceramic filler particles are functionalized with a reactive group and configured to convert to the ceramic phase;
- an energy source proximate to the bath;
- and
- a controller coupled to the energy source and configured to apply the energy source to the resin to create at least one layer of the ceramic phase from the resin.
A resin for additive manufacturing of ceramics, the resin comprising:
- a preceramic polymer wherein the preceramic polymer is configured to convert to a ceramic phase;
- and
- inorganic ceramic filler particles dispersed in the preceramic polymer, wherein the inorganic ceramic filler particles are functionalized with a reactive group and configured to convert to the ceramic phase.
