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.
Claims19
A method for additive manufacturing of a ceramic structure, the method comprising:
- providing a first layer of resin, the resin comprising a preceramic polymer and a plurality of first inorganic filler particles dispersed in the preceramic polymer wherein the first inorganic filler particles have functional groups that are configured to convert to a ceramic phase and wherein the preceramic polymer is configured to convert to the ceramic phase;
- applying an energy source to the first layer of resin to create a first ceramic layer;
- disposing a second layer of resin at least partially on the first ceramic layer, the second layer of resin comprising the preceramic polymer and a plurality of second inorganic filler particles dispersed in the preceramic polymer, wherein the second inorganic filler particles have functional groups that are configured to convert to a ceramic phase and wherein the preceramic polymer is configured to convert to the ceramic phase;
- applying an energy source to the second layer of resin to create a second ceramic layer, wherein the second ceramic layer has a different composition, crystallinity or both compared to the first ceramic layer.
A ceramic structure comprising a first ceramic layer comprising first inorganic filler particles dispersed within the first ceramic layer and bound to the first ceramic layer and and a second ceramic layer at least partially disposed on the first ceramic layer, wherein the second ceramic layer has a different composition, crystallinity or both compared to the first ceramic layer.
