A system and method for the manufacture of wind turbine blade moulds and wind turbine blade mould plugs is described. The method comprises dividing a blade mould geometry (70) or plug geometry into separate geometrical slices or segments. The separate slices can then be used to control a cutting of blank elements (78) to form separate cut surfaces (82). The cut surfaces are used to form a consolidated wind turbine mould surface.

Provided is a base (1) for a flexible mold, including: a glass sheet (2); a resin sheet (3); and a bonding layer (4) configured to bond the glass sheet (2) and the resin sheet (3) to each other, wherein the resin sheet (3) protrudes from the glass sheet (2).

A hybrid mold includes (a) an Invar® eggcrate structure, (b) an Invar® interim working surface and (c) a CF composite material overlay. The eggcrate and interim working surface are welded or otherwise connected together to form a unitary base mold. The CF overlay is bonded to the interim working surface. The CF overlay is easily reconfigurable and can be replaced without destroying the integrity of the base mold.

A method for manufacturing an imprint mold which can prevent accumulation of the transferring resin at the joining portion of the film mold is provided. A method for manufacturing an imprint mold, including a winding step to wind a resin film mold onto a cylindrical transferring roll, the resin film mold being provided with a reverse pattern of a desired fine concave-convex pattern and the resin film mold being wound onto the transferring roll so that a gap without the reverse pattern is provided at a butting portion of both ends of the resin film mold; a resin filling step to fill a resin composition into the gap; and a pattern forming step to form a pattern substantially the same as the reverse pattern onto the resin composition, is provided.

Moulding tool, for compression moulding and or in mould foaming of automotive trim parts, comprising at least one mould having a 3D shaped cavity, characterised in that the mould part comprises a thermoset resin binder matrix with particulates bound within the matrix.

A mold for forming a flange of a wind turbine blade comprising a first flange portion including a plurality of lamina and having a generally planar shape and a second perpendicular flange including a plurality of lamina. A plurality of copper wires are disposed within the lamina for conducting heat delivered from a base portion through the first and second flange portions. The mold is free of fluid conduits with the flange portions moveable relative to the base portion.

A part formed by additive manufacturing includes a plurality of layers including a first layer and a second layer, the first layer and the second layer being stacked along a stacking direction, and a work surface formed on an upper surface of the first layer and an upper surface of the second layer. The part also includes a first through-hole formed in the first layer, a second through-hole formed in the second layer, the second through-hole being at least partially aligned with the first through-hole, and a wall extending from the first through-hole to the work surface.

Techniques for evaluating support for an object to be fabricated via an additive fabrication device are provided. In some embodiments, a three-dimensional representation of the object is obtained and a plurality of voxels corresponding to the representation of the object is generated. A first supportedness value may be assigned to a first voxel of the plurality of voxels based on an amount of support provided by a support structure to the first voxel, and a second supportedness value determined for a second voxel of the plurality of voxels, wherein the second voxel neighbors the first voxel, and wherein the second supportedness value is determined based on the first supportedness value of the first voxel and a weight value representing a transmission rate of supportedness through voxels of the plurality of voxels.

A method for manufacturing a molding mold used in an injection molding apparatus includes: generating a first plasticized material by plasticizing a first shaping material containing an amorphous metal and a resin; and shaping a laminate that is a part of the molding mold by discharging the first plasticized material toward a stage to laminate a layer.

A method for producing molded parts from a sinterable mixing compound using a cold casting mold having a cavity that corresponds geometrically to the molded part and at least one opening into the cavity, wherein the mold is additively constructed from a starting material, in particular a 3D printing method using a 3D printer, and wherein the cavity is created on the basis of a digital data set, in particular based on a three-dimensional model of the oral cavity of a patient. The cavity is filled via the opening with the sinterable mixing compound, curing and/or solidifying the mixing compound, wherein gases and/or liquids contained in the mixing compound are discharged from the cavity via the opening, thermally and/or thermochemically decomposing the mold at a temperature from 200° C. to 2500° C. and sintering the mixing compound to hardness at a temperature from 900° C. to 2500° C. until a molded part is obtained.
