A method for manufacturing a fiber-reinforced hollow structural component includes introducing a mold core and fibers with a matrix material into a molding tool. A first fiber unit is located between the mold core and the molding tool to at least partially form a component wall. The matrix material is cured to form the hollow structural component and the mold core is flushed out of the hollow structural component to form a component cavity. At least one channel may extend through the mold core so that after the matrix material has cured and the mold core has been flushed out, a reinforcing strut is formed. A related hollow structural component is also disclosed.

A fabrication method involving the use of additive material fabrication methods to create a shell representative of a desired part, the additive material shell being used in one or more molding fabrication methods in which a second material is provided into a cavity of the shell.

A method of fabricating a casting, the method including applying a substrate to a sacrificial mold, the sacrificial mold including a shaped non-planar receiving surface to receive the substrate and provide a casting of the substrate having a shaped structure corresponding to the receiving surface; and subjecting the sacrificial mold and casting to freeze drying conditions and sublimating the sacrificial mold from the casting to form a cast article including the shaped non-planar structure.

A method of manufacturing a microfluidic architecture having at least one channel disposed therein. Steps can include pouring an uncured polymeric material into a mould to produce a first layer; at least partially curing the first layer; and forming the at least one channel by disposing a support material on the first layer; pouring an uncured polymeric material onto the first layer to form a second layer to thereby encapsulate the support material; and at least partially curing the second layer such that the first layer and second layer together form the microfluidic architecture; wherein the support material undergoes a phase change during the process of forming the at least one channel. The phase change of the support material enables the material to be more easily disposed and/or removed after formation of the channel.

The present invention relates to a material system for 3D printing, to a 3D printing process using a lignin-containing component or derivatives thereof or modified lignins, to soluble moldings that are produced by a powder-based additive layer manufacturing process and to the use of the moldings.

A method of forming a model of a porous structure includes three dimensionally printing a mold of the porous structure using a polycaprolactone mold material, filling the mold with a polymer mixture, and heating the filled mold at a temperature above a melting temperature of the mold material to cure the polymer mixture, where the cured polymer mixture forms the model of the porous structure.
