Abstract

An arrangement (10) for additive manufacturing of a structure, preferably an architectural structure, the arrangement comprising a nozzle (20) having a construction material outlet (27) configured to extrude construction material in the form of a hollow core bead (30) along a manufacturing path (M; M') defined by multiple points (A), a fluid outlet (31) configured to inject a fluid into the hollow core of the extruded bead, a fluid pressure adjusting device (21) configured to adjust a pressure of the fluid injected into the hollow core of the extruded bead via the fluid outlet, and a control unit (22) configured to determine a pressure value (P) assigned to a point of the manufacturing path and to control the fluid pressure adjusting device on the basis of the determined pressure value. Furthermore, a method for generating control data for such an arrangement is disclosed.
