Abstract:

A series of experiments were carried out with Selective Laser Sintering (SLS) for the mixture of Ni based alloys powders and copper powders. First, a sintering model was established, then according to the phenomena of the sintering process, the effect of the technological parameter upon metal forming was analyzed and discussed in detail, and finally the mechanism of the laser sintering metallic powders was explored preliminarily. All those above lay the foundation for the forming metal spare parts by laser sintering metallic powders.

Key words: selective laser sintering, metallic powder, process parameters, metallic parts
