摘要	Cu reticulated mesh and stochastic open cellular foams were fabricated by additive manufacturing using electron beam melting. Fabricated densities ranged from 0.73 g/cm(3) to 6.67 g/cm3. The precursor Cu powder contained Cu(2)O precipitates and the fabricated components contained arrays of Cu(2)O precipitates and interconnected dislocation microstructures having average spacings of similar to 2 mu m, which provide hardness values similar to 75% above commercial Cu products. Plots of stiffness (Young's modulus) versus density and relative stiffness versus relative density were in very close agreement with the Gibson-Ashby model for open cellular foams. These open cellular structure components exhibit considerable potential for novel, complex, multi-functional electrical and thermal management systems, especially complex, monolithic heat exchange devices.
