Patent ID: 11148357

Abstract:
A method of making a composite article comprised of a first component (10) and a second component (30) includes (a) providing a first component (10) and an optically transparent member (22) having a build surface with the first component having a first three-dimensional interfacing segment formed thereon; (b) immersing the first three-dimensional interfacing segment in polymerizable liquid (21); (c) forming an intermediate object by irradiating a build region with light through an optically transparent member and also advancing the first three-dimensional component and the build surface away from one another to form from the polymerizable liquid (21) a second component (30) on said first three-dimensional interfacing segment, with the second component including a second three-dimensional interfacing segment in contact with the first three-dimensional interfacing segment; then (d) optionally washing the intermediate; and then (e) further solidifying the second three-dimensional component (30) on said first three-dimensional component (10) to form said composite article.
