Dear Artur Mateus,
In 1996 in our research group the conditions of a direct selective laser
sintering were researched experimental in a volume and by layers for the
eutectic and near-eutectic powder compositions, which usually used for the
self-propagating high-temperature synthesis (SHS) technology. It was shown
a possibility to realise during SLS process a control exothermal reaction
of combustion exactly in the focus of cw-laser beam on Nd-YAG. The 3D parts
from intermetallic compounds were created without any post-process
procedures (see more http://www.fian.samara.ru/sh-htm/sh-paper4.htm)
In principle, a control chemical reaction in the focus of laser beam could
be realized also. For example, in our last year researches a layer by
layer selective laser sintering process out of stoichiometric oxide powder
mixture (PbO, ZrO2 and TiO2) has been developed. X-ray structural analysis
shown, that the simultaneous synthesis and formation of porous PZT ceramics
occurred during SLS from oxide's mixture.

If you have interest, we are glad to discuss any forms collaborations.
Best regards.
