Abstract: An industrial asset item definition data store may contain at least one electronic record defining the industrial asset item. An automated support structure creation platform may include a support structure optimization computer processor. The automated support structure optimization computer processor may be adapted to automatically create support structure geometry data associated with an additive printing process for the industrial asset item. The creation may be performed via an iterative loop between a build process simulation engine and a topology optimization engine.

Abstract: Some aspects are directed to additive manufacturing systems. An example additive manufacturing system controller is configured to receive a build file comprising instructions for controlling the manufacturing hardware to generate the object, receive a material identifier indicating a particular lot of manufacturing media, validate the build file and the material identifier via a distributed ledger to verify at least one of an author of the build file or an origin of the particular lot of manufacturing media, control the manufacturing hardware using the build file to generate the object using the particular lot of manufacturing media, and in response to completion of the generation of the object, generate an object manufactured transaction to the distributed ledger indicating a result of the validation of the origin of the at least one of the build file or the material identifier.

Abstract: Frame assemblies, molds, and methods for forming rotor blades are provided. A frame assembly for a rotor blade mold includes a plurality of frames, at least one of the plurality of frames movable relative to the others of the plurality of frames, and a bed supported by the plurality of frames. Movement of the at least one of the plurality of frames causes a modification of the bed along a width-wise axis. A mold for forming a rotor blade includes a frame assembly and a mold material disposed in the bed of the frame assembly.

Abstract: A method for recycling a used rotor blade of a wind turbine includes processing the used rotor blade into a plurality of material fragments. The method also includes treating the plurality of material fragments to remove at least a portion of the at least one composite material and expose the at least one fiber material of the used rotor blade. Further, the method includes mixing the treated plurality of material fragments with, at least, an alkali activator to form a usable geopolymer concrete.
