Abstract: A mold assembly for use in manufacturing parts includes a first and second mold halves and a mold temperature control system. The first mold half comprises at least a first mold cavity and a first coolant passage. The second mold half comprising at least a second mold cavity and a second coolant passage. The mold temperature control system is in fluid communication with the first and second coolant passages of the first and second mold half. The mold temperature control system comprises a fluid, a means to control the temperature of the fluid, and a pump to circulate the fluid through the mold temperature control system and the first and second coolant passages.

Abstract: Modified nanocellulose particle include a nanocellulose particle, a binder coating the particle, and an alkyl amine affixed to the binder coating. A method of modifying nanocellulose particles includes adding a binder and a hydrophobizing agent to a slurry of nanocellulose particles in water, modifying the nanocellulose particles with the binder and hydrophobizing agent, and collecting the modified nanocellulose particles.

Abstract: A method for sealing gaps in a component including generating vapor from a liquid; directing the vapor to an exposed surface of the component, wherein the component includes a plurality of layers of an extrudate and gaps between the plurality of layers and wherein the extrudate includes an outer portion; softening the outer portion of the extrudate at the exposed surface; and filling the gaps with softened outer portion of the extrudate. An apparatus includes a heating chamber including at least one first heating element; a vapor chamber coupled to the heating chamber; a pressure regulator operatively coupled to the vapor chamber; and a nozzle coupled to the vapor chamber by a duct.

Abstract: A system for manufacturing a multiple layer filament produces a multiple layer filament including a continuous core, a first layer and a second layer. The continuous core includes one of a continuous fiber, a braided strand, a metal wire and a narrow gauge filament. The materials for the first and second layers of the multiple layer filament are chosen from a plurality of materials with each of the plurality of materials providing a specific function or multiple functions that are required for the particular application of the three-dimensional object manufactured using the multiple layer filament.
