In this paper two processes of microfabrication technology are investigated. In the first part, laser generating process which is largely affected by the beam interaction time is described. In the second part, selective laser sintering of metallic powder shall be discussed. The results show that the two metal liquid phase sintering is most effective in the selective laser sintering of the metallic powder comprising of high and low melting point. Whereas in the generating process the beam interaction time greatly affect the structural development of the product with respect to its strength and quality. A few examples are demonstrated briefly.
