The technology of repressing and re-sintering in powder metallurgy had been used to fabricate a c Cu-C composite materials attaining above 95% of the theoreticaldensity.
A case study on SLS of this Cu-based metal powder to fabricate a gear is carried out. 82% relative theoreticaldensity and transverse dimension error of 1.9% are achieved.
