Abstract:
A process for producing an article by three-dimensional printing includes applying a 1,1-di-activated vinyl compound-containing liquid binder over a predetermined area of a layer of solid particles. The liquid binder infiltrates gaps between the solid particles to form a first cross-sectional layer of an article, and the 1,1-di-activated vinyl compound reacts to solidify the liquid binder and bind the solid particles in the first cross-sectional layer of the article. Also provided is an article produced by the three-dimensional printing process, set forth herein.
