A method for producing a device having at least one internal feature includes manufacturing an internal volume of the internal features out of a first material, disposing the internal volume in a parent material that has a higher melting point than the first material, causing the internal volume to melt within the parent material, and allowing at least a portion of the first material to diffuse into the parent material, thereby leaving behind the at least one internal feature within the parent material.

A high precision Interface Node is disclosed. The Interface Node includes an integrated structure including one or more complex or sophisticated features and functions. The Interface Node may connect with another component or a Linking Node. The Interface Node is manufactured to achieve high precision functionality while enabling volume production. Current additive manufacturing technologies allow for the printing of high precision features to be manufactured, but generally this is performed at a slower rate. Consequently, in one aspect, the size of the Interface Nodes is reduced in order to overcome at least part of the slower production volume caused by creating the high precision Interface Nodes. The components and Linking Nodes to which the Interface Node is connected may only have basic features and functions. Accordingly, this latter category of components may use a high print rate and thus high production volume. In other embodiments, these low precision components may also be produced using a non-print manufacturing technology, such as casting, forging, etc., that may provide the requisite high throughput, or to high precision machined parts that lack the geometric flexibility of the Interface Node. In an embodiment, the Interface Nodes may be connected to other components via a Linking Node.

A castable, moldable, and/or extrudable structure using a metallic primary alloy. One or more additives are added to the metallic primary alloy so that in situ galvanically-active reinforcement particles are formed in the melt or on cooling from the melt. The composite contains an optimal composition and morphology to achieve a specific galvanic corrosion rate in the entire composite. The in situ formed galvanically-active particles can be used to enhance mechanical properties of the composite, such as ductility and/or tensile strength. The final casting can also be enhanced by heat treatment, as well as deformation processing such as extrusion, forging, or rolling, to further improve the strength of the final composite over the as-cast material.
