Abstract: A system for forming an article includes a polymer resin formulation formed of a semicrystalline polymer material having a first fiber content and an amorphous polymer material having a second fiber content. The first fiber content is higher than the second fiber content. Further, the semicrystalline and amorphous polymer materials are blended together to form the polymer resin formulation having a blended fiber content of greater than 10% by weight. Moreover, the polymer resin formulation is amorphous. The system also includes a computer numeric control (CNC) device for printing and depositing the polymer resin formulation layer by layer to form the article.

Abstract: Methods for joining a first blade component and a second blade component of a rotor blade together includes printing and depositing, via a computer numeric control (CNC) device, at least one three-dimensional (3-D) grid structure at a first joint area of the rotor blade. The first joint area contains the first blade component interfacing with the second blade component. The method also includes providing an adhesive at the first joint area to at least partially fill the grid structure. Further, the method includes securing the first blade component and the second blade component together at the first joint area via the adhesive.

Abstract: A system for manufacturing a panel includes a forming assembly having opposing press plates and at least one platen assembly arranged between the opposing press plates. The platen assembly includes first and second platens connected together via at least one elastic deformable member. Further, the forming assembly is operable in a heating mode and a cooling mode. Moreover, the first platen is maintained at a predetermined temperature range during each of the heating and cooling modes. During the heating mode, the elastic deformable member(s) is compressed such that the first and second platens contact each other. As such, one or more layers of material to be consolidated are held by the forming assembly as the forming assembly applies heat and pressure to the layer(s), thereby consolidating the panel.

Abstract: A modular extrusion system for forming an article includes a support frame and a plurality of print head modules removably connected to the support frame. Each of the print head modules includes a printer head, a printer nozzle, a hopper, and an integrated control module. The hoppers are configured for holding a plurality of polymer pellets. The printer heads of the plurality of print head modules each include a body defining a barrel, a rotating extrusion screw extending through the barrel, and one or more heaters at least partially surrounding the barrel for melting the plurality of polymer pellets into a polymer resin formulation. The printer nozzles are configured for printing and depositing the polymer resin formulation onto a substrate to form the article. The modular extrusion system also includes a control system communicatively coupled to each of the integrated control modules for controlling the modular extrusion system.

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 printheads 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 printheads is moveable along the first axis, the second axis, or both.

Abstract: A system for manufacturing a panel includes a support frame, a first caul plate arranged atop the support frame, a second caul plate arranged atop the first caul plate, and a heating assembly having a housing defining an inlet and an outlet. The housing includes one or more heaters. The heater(s) is configured to generate heat and the housing is configured to generate a first pressurized gas film. Thus, one or more layers of material to be consolidated may be placed between the first and second caul plates and drawn through the heating assembly as the heating assembly applies pressure to the one or more layers of material to be consolidated via the first pressurized gas film in combination with applying the heat via the one or more heaters, thereby consolidating the panel.

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.
