Abstract
A 3D printing system configured to embed and orient reinforcing fibers in a printable matrix material in at least three directions, wherein at least one of the directions is non-parallel with a plane defined by two other of the directions. The 3D printing system may be configured to deposit a layer of printable non-metallic material along a printing path on a contoured printing surface to form a 3D printed article. The system can carry out a method of 3D printing a fiber-reinforced article that includes the steps of: depositing a plurality of layers of printable matrix material one over another to define a three-dimensional shape of the article; and embedding a reinforcing fiber in the printable matrix material during the step of depositing, with the reinforcing fiber extending into more than one of the plurality of material layers.
