Abstract
A core-shell particle is provided, including a core particle composed of a non-reactive component, and a coating layer disposed about the core particle, the coating layer composed of reactive component. The reactive component is chemically reactive with water, acid, or base, and the non-reactive component is non-reactive with water, acid, or base. Also provided are a bulk composition composed of the core-shell particle, an article composed of the bulk composition, as well as method and system of making and using the particles, composition, and articles.

A bulk composition having a multiphase morphology, the bulk composition comprising:
- a continuous phase of a matrix material comprising a reactive component that is chemically reactive with neutral water, acidic water, or basic water via a chemical displacement reaction;
- and
- a discontinuous phase including a plurality of particles of a non-reactive component that are chemically unreactive with neutral water, acidic water, or basic water via a chemical displacement reaction;
- wherein the plurality of particles are distributed within the matrix material.

A method comprising:
- depositing a reactive component onto a plurality of core particles of a non-reactive component;
- wherein the deposited reactive component forms layers about the plurality of core particles, thereby forming a plurality of core-shell particles;
- wherein the reactive component is chemically reactive with neutral water, acidic water, or basic water via a chemical displacement reaction, and wherein the non-reactive component is chemically unreactive with neutral water, acidic water, or basic water via a chemical displacement reaction.

A method of additive manufacturing an article, the method comprising:
- depositing a layer onto a build plate;
- additive manufacturing an article from a material onto the layer, such that the layer is positioned between the material and the build plate;
- after additive manufacturing of the article, contacting the layer with water until the layer dissolves, such that the article is separated from the build plate and the layer;
- and
- retrieving the article.
