CPC Class B33Y

A mold assembly for use in forming a component having an outer wall of a predetermined thickness is provided. The mold assembly includes a mold that includes an interior wall that defines a mold cavity within the mold. The mold assembly also includes a jacketed core positioned with respect to the mold. The jacketed core includes a jacket that includes an outer wall. The jacketed core also includes a core positioned interiorly of the jacket outer wall. The jacket separates a perimeter of the core from the mold interior wall by the predetermined thickness, such that the outer wall is formable between the perimeter and the interior wall.

An article comprises a plurality of micro-sized or nano-sized galvanic cells, wherein the article has a seamless structure encompassing a plurality of empty spaces of different sizes, geometries, distributions, or a combination thereof, and one or more of the following properties of the article vary in different directions: tensile strength; compressive strength; electrical resistance; thermal conductance; modulus; or hardness.

An additive manufacturing system includes a platen having a top surface to support an object being manufactured, a dispenser to deliver a plurality of successive layers of precursor material over the platen, a plurality of lamps disposed below the top surface of the platen to heat the platen, and an energy source to fuse at least some of the outermost layer of precursor material.

A method of operating a Continuous Liquid Interface Printing (CLIP) printer can include receiving a set of objectives for fabrication of an object using a CLIP printer and determining an orientation for fabrication of the object based on fulfillment of the set of objectives by simulated fabrication of the object.
