Abstract

A device for producing a three-dimensional shaped object, including a substrate part having a base surface for holding the shaped object, a first reservoir for holding a flowable first material, a second reservoir for holding a flowable second material, a dispensing mechanism for dispensing material portions of the first material, a material application mechanism including an application roll and a coating mechanism for applying a second material layer of the second material, and a fixation mechanism for solidifying the material layers composed of the first material and the second material. The transfer body rotates about an axis of rotation disposed parallel to the base surface, the dispensing mechanism and the application roll r relative to the substrate part about an axis disposed normal to the base surface, the application roll is conical, and an axis of rotation of the application roll intersects the axis disposed normal to the base surface.
