Abstract: A method for manufacturing a tower structure of a wind turbine at a wind turbine site. The method includes determining an optimized shape of the tower structure based on one or more site parameters. Further, the optimized shape of the tower structure is non-symmetrical. In a further step, the method include printing, via an additive printing device, the optimized shape of the tower structure of the wind turbine at the wind turbine site, at least in part, of a cementitious material. In addition, the method includes allowing the cementitious material to cure so as to form the tower structure of the wind turbine.

Abstract: A method of manufacturing a tower structure includes providing an additive printing device having at least one printer head atop a support surface. The method also includes positioning a pre-fabricated component adjacent to the support surface. The pre-fabricated component is constructed of a composite material reinforced with a plurality of reinforcement members. Further, portions of the plurality of reinforcement members protrude from the composite material. Moreover, the method includes printing and depositing, via the at least one printer head, a cementitious material onto the support surface to build up the tower structure layer by layer around the pre-fabricated component. Thus, the portions of the plurality of reinforcement members that protrude from the composite material reinforce the cementitious material around the pre-fabricated component.

Abstract: A method for manufacturing a tower structure of a wind turbine includes additively printing at least a portion of a frame shape of the tower structure of the wind turbine of a first material on a foundation of the tower structure. Further, the first material has a first cure rate. The method also includes allowing the portion of the frame shape to at least partially solidify. The method includes providing a second material around and/or within the portion of the frame shape such that the portion of the frame shape provides support for the second material. The second material includes a cementitious material having a second cure rate that is slower than the first cure rate, with the different cure rates reducing the net printing time for the overall structure. Moreover, the method includes allowing the second material to at least partially solidify so as to form the tower structure.
