Abstract
An apparatus for forming a three-dimensional (3D) object includes a 3D printing head, for fabricating a first portion of the 3D object by forming a plurality of successive layers of a first material. The apparatus also includes a delivery head for fabricating a second portion of the 3D object by dispensing onto the first portion of the 3D object a plurality of layers of a continuous-fiber reinforced second material. Further, the delivery head includes comprising a roller for pressing the continuous-fiber reinforced second material into place during the dispensing thereof. A controller controls the 3D printing head and the delivery head to cooperatively form the 3D object, based on a dataset corresponding to a 3D object model.
