a Tensile engineering stress-strain curves and the fracture surface morphology of the L-PBF fabricated pure Cu (a1) and 1.0LaB6-Cu (a2). The error bars represent the standard deviation of the mean. b Comparison of the yield strength, elongation to failure and electrical conductivity obtained in the present work with previously published data of high-performance Cu, Cu alloys and Cu matrix composites fabricated by L-PBF, L-PBF plus heat treatment and traditional processing12,13,19,21,22,24,25,34,35,36,37,38,39,40,41,42,43. Note that the columns and corresponding values represent the electrical conductivity (IACS, International Annealed Copper Standard). Source data are provided as a Source Data file.
