Title: Silicone formulations for 3D printing

Abstract

In one embodiment, a silicone-based ink for additive manufacturing includes a vinyl-terminated siloxane macromer, a hydrophobic reinforcing filler, and a rheology modifying additive. In another embodiment, a method of additive manufacturing with silicone-based ink includes adding a mixture that includes a vinyl-terminated siloxane macromer, a hydrophobic reinforcing filler, and a rheology modifying additive to a cartridge for additive manufacturing, extruding the mixture through the cartridge to form a structure, and curing the mixture to at least a predefined extent.
