Abstract
A product of additive manufacturing with a silicone-based ink having core-shell microspheres, where the product has a plurality of continuous filaments. The product includes a plurality of core-shell microspheres. Each core-shell microsphere includes a polyorganosiloxane shell and one or more cores inside the shell, at least one of the cores having a carrier and at least one component configured to be released post processing. An average diameter of the cores of the plurality of core-shell microspheres is in a range of greater than 2 μm to less than about 100 μm.
