Abstract: A method for forming an article includes placing at least one forming tool of the article adjacent to a substrate, the at least one forming tool having a predefined shape and/or height. The method also includes extruding a bead of material from a printer head of a print head assembly directly into or onto the forming tool(s) of the article so as to increase a height of the bead of material via the forming tool(s), thereby reducing or eliminating a number of extruded layers of the material. Further, the method includes allowing the material to solidify to form the article. Thus, by using the forming tool(s), multiple printed layers of the material can be eliminated or reduced.

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.

Abstract: A method for manufacturing a tower structure of a wind turbine includes printing, via an additive printing device, the tower structure of the wind turbine of a cementitious material. During printing, the method includes embedding one or more reinforcement sensing elements at least partially within the cementitious material at one or more locations. Thus, the reinforcement sensing element(s) are configured for sensing structural health of the tower structure, sensing temperature of the cementitious material, heating to control cure time of the cementitious material, and/or reinforcing the cementitious material. In addition, the method includes curing the cementitious material so as to form the tower structure.

Abstract: The present disclosure is directed to an apparatus for manufacturing a composite component. The apparatus includes a mold onto which the composite component is formed. The mold is disposed within a grid defined by a first axis and a second axis. The apparatus further includes a first frame assembly disposed above the mold, and a plurality of machine heads coupled to the first frame assembly within the grid in an adjacent arrangement along the first axis. At least one of the mold or the plurality of machine heads is moveable along the first axis, the second axis, or both. At least one of the machine heads of the plurality of machine heads is moveable independently of one another along a third axis.

Abstract: A wind turbine rotor blade may generally include a blade root, a blade tip opposite the blade root and a body shell extending between the blade root and the blade tip. The body shell may include a pressure side and a suction side extending between a leading edge and a trailing edge and may define an outer shell surface. The rotor blade may also include a leading edge cap coupled to the body shell at the leading edge. The leading edge cap may be formed from a fiber-reinforced composite including an inner surface extending directly adjacent to the body shell along a portion of the outer shell surface and an outer surface opposite the inner surface. The fiber-reinforced composite may include a plurality of fibers surrounded by a thermoplastic resin material, with the thermoplastic resin material extending throughout the fiber reinforced composite from the inner surface to the outer surface.

Abstract: The present disclosure is directed to tip extensions for wind turbine rotor blades and methods of installing same. The method includes removing a removable blade tip of a lightning protection system from the rotor blade so as to expose a down conductor of the lightning protection system. The method also includes securing a conductive extension to the down conductor. Moreover, the method includes sliding the first end of the tip extension over the conductive extension so as to overlap the rotor blade at the tip end. In addition, the method includes securing the removable blade tip to the conductive extension at the second end of the tip extension. Further, the method includes securing the tip extension to the rotor blade.

Abstract: A rotor blade segment of a wind turbine includes a seamless leading edge surface. A method of manufacturing a rotor blade segment of a wind turbine, the rotor blade segment having a seamless leading edge surface, includes forming an outer skin of the rotor blade segment. The outer skin defines a continuous outer surface. The continuous outer surface includes a pressure side surface extending between a pressure side aft edge and a pressure side forward edge, a suction side surface extending between a suction side forward edge and a suction side aft edge, and the seamless leading edge surface extends between the pressure side forward edge and the suction side forward edge. After folding the outer skin, the pressure side surface is positioned opposite the suction side surface and the pressure side aft edge is proximate the suction side aft edge.
