Abstract
Ceramic inks formulated for additive formation of proppants are provided, as well as methods of manufacturing such ink and ink systems including such ink. The proppant formed can contain a proppant core, a proppant shell, a proppant outer coating or any combination thereof. Additive methods for forming proppants are also provided. The ceramic ink can be applied drop-wise, linearly, in a planar fashion, or any combination thereof to form proppants. Additive fabricators configured to produce proppant are further provided, as are systems including the same and software for running the same.
