Abstract: A vapor chamber includes a wick structure created by an additive selective laser sintering process. The wick structure includes a substrate, a first copper powder layer, a second copper powder layer, and a plurality of additional layers. The first copper powder layer is deposited across the substrate, wherein the first copper powder layer is subsequently selectively fused via a fusing instrument. The second copper powder layer is deposited across the first copper powder layer, wherein the second copper powder layer is subsequently selectively fused via the fusing instrument. Additionally, a plurality of additional copper powder layers are deposited wherein each additional layer is deposited on the previous layer, wherein each of the additional copper powder layers is selectively fused with a predetermined structure.

The first thermoplastic and/or wax-type material and the second thermoplastic and/or wax-type material differ in at least one property which property is selected from (1) solubility in a solvent, (2) degradability induced by heat and/or a reactant, and (3) volatility. The first thermoplastic and/or wax-type material is less soluble, less degradable or less volatile than the second thermoplastic and/or wax-type material. Tcross is below 120° C., wherein Tcross is the temperature at the intersection between the storage modulus G′ curve and the loss modulus G″ curve in a dynamic viscoelasticity measurement of the binder component. The feedstock compound containing the binder component and non-organic sinterable particles is used in an additive manufacturing process, an injection molding process, a pressing process or a casting process.
