The laser selectively fuses the powder materials by scanning 2D layers sliced from a 3D description of the part on the powder bed.
Direct experimental studies are highly difficult to be carried out due to the high temperature conditions prevailing in the material, since most of the materials are metals.
Fig 2 Temperature contour with fusion boundaries The temperature distribution is very important in this study in order to find the depth of heat penetration and also to optimize the parameters for different materials used for SLS, by understanding the physical phenomenon we have an advantage of processing new materials using this process.

This aspects are is imposed by the development process of thermo and mass transfer of finishing agents into the textile structure materials applied in dentistry (fibers, yarns, fabric, nonwovens).
The intensification of transfer processes into the textile materials is realized in conventional finishing textile industry (washing, cleaning, and coloring) by using high work temperature.
The recently laboratory scientific research showed that the use of ultrasonic systems in finishing textile materials contributes both to the acceleration of thermo and mass transfer and to the decreasing of active chemical substances.
Under the REACH Low the colorants producers together with the complementary industries for materials finishing try to orientate the products to a great content of solid substance, low content of solvents and to products which are able to dissolve in water.
