Abstract: The invention relates to an additive manufacturing system (1) and a method for manufacturing one or more three-dimensional structures. At least one deposition unit (3) with one or more nozzles (5) is arranged for dispensing a build material through an opening area thereof on a print surface (7). A controller is provided which is configured to operate the system (1) for deposition of filaments of a build material paste on the print surface (7) in an interconnected arrangement in a plurality of stacked layers in order to form the one or more three-dimensional structures. An actuation unit (9) is arranged in order to have printing access to the at least one deposition unit (3), wherein the actuation unit (9) is configured to hold the print surface. The controller is configured to control the actuation unit (9) so as to move the print surface (7) at the at least one deposition unit (3) during deposition of the filaments by said deposition unit. The one or more nozzles (5) of the at least one deposition unit (3) are arranged to remain stationary during the deposition of the filaments.
