A system for additively manufacturing an object comprises a fiber supply that dispenses elongate fibers, a resin supply that applies a resin to the elongate fibers to create a feedstock line with the resin in a first non-rigid uncured state, a rigidizing mechanism that transforms the resin from the first non-rigid uncured state to a rigid uncured state, a delivery guide that deposits the feedstock line along a print path, a feed mechanism that feeds the feedstock line through the delivery guide, a de-rigidizing mechanism that transforms the resin from the rigid uncured state to a second non-rigid uncured state, and a curing mechanism that transforms the resin from the second non-rigid uncured state to an at least partially cured state.

A method of additively manufacturing an object comprises applying a resin in a first non-rigid uncured state to elongate fibers to create a feedstock line, transforming the resin of the feedstock line from the first non-rigid uncured state to a rigid uncured state, introducing the feedstock line into a delivery guide with the resin of the feedstock line in the rigid uncured state, transforming the resin of the feedstock line from the rigid uncured state to a second non-rigid uncured state as the feedstock line passes through the delivery guide or as the feedstock line exits the delivery guide, depositing the feedstock line along a print path, and at least partially curing the resin of the feedstock line after the feedstock line is deposited by the delivery guide along the print path.

A method suitable for manufacturing complex and stable objects of a wide range of sizes. The method involves producing an object structure by a generative production method and/or by an injection molding method, and producing a fiber-reinforced resin layer in at least one sub-region of the object structure.

What is presented is a unit cell comprising a cellular geometry that comprises cell walls and cell edges arranged into a combination of a cubic cell geometry and a tetrahedral cell geometry arranged to have a coincident central vertex. The cubic cell geometry comprises three orthogonal cell faces that intersect at its central vertex. The tetrahedral cell geometry comprises an arrangement of eight tetrahedral cells that share its central vertex such that each tetrahedral cell shares three coincident edges with three other tetrahedral cells in a cubically symmetric arrangement. The tetrahedral cell geometry is combined with the cubic cell geometry such that all vertices of the tetrahedral cell geometry are coincident with the vertices of the cubic cell geometry.

In some embodiments selected cell walls may have one or more holes. Selected cell edges of some embodiments of unit cell may have varying cross-sectional geometry that vary along a length of the cell edge. Some embodiments of the unit cell may comprise fillets to blunt stress concentrations.

The invention relates to a method of manufacturing a shell part (101) for a wind turbine blade also comprising an add-on component (301, 302) connected to the shell part (101) along a connection face. The method comprises the steps of providing an insert (102) with a side surface of approximately the same shape as the connection face, positioning the insert in an open mould, and placing one or more layers (105) of material in the mould (103) to form the shell part (101) wherein the layers (105) are placed in abutment to the side surface (104) of the insert (102) thereby forming a side surface (108) of the shell part (101) of approximately the same shape as the connection face. After resin cure, the insert (102) is removed. The invention further relates to a method of manufacturing a wind turbine blade shell member (100) comprising such a shell part (101), and layers (105) of material are placed in the mould (103) in abutment to the side surface (108) of the shell part (101) to form the add-on component (301, 302).

A molding system and a method for operation of the molding system are provided. The method includes flowing a molten polymeric material from an upstream device into an in-mold tuning chamber in a filling position where the in-mold tuning chamber is positioned at least partially within a mold cavity. The method also includes adjusting at least one of a temperature of and a pressure applied to the molten polymeric material in the in-mold tuning chamber to create a first tuned molten polymeric material and releasing the tuned molten polymeric material into the mold cavity from the in-mold tuning chamber.

The reinforcing structure for a tire is in the form of a stratified assembly formed of two layers of reinforcing strips of completely connected cross section, and flattened in shape. According to the method, the strips of each layer are laid side by side in a main direction of laying. The strips of the first layer are spaced apart by a distance that is less than the width of the strips of the second layer and in such a way that the edges of the strips of the first layer overlap the edges of the strips of the second layer. The two layers of strips are separated by a layer of uncoupling rubber.
