Abstract

Method And Device for rapid prototyping by selective laser sintering where the computerized controlled Co2 laser beam passes through the static beam expander. The expanded beam oriented through the mirrors and enters in the dynamic beam expander. This laser beam fall on the surface of the field, after passes through the x- axis mirror mounted on galvo motor and y- axis mirror mounted on galvo motor. The beam layeY goes on increase as it moves away from the center, the diameter of the beam slightly expand to make the spot constant again the field to make the spot fall on the flat field other than forming the parabolic surface. The laser beam fall on the field (x, y) sinter the power which is collected in the powder collector tray and form the scanning cross-sections generated from a 3-D digital description object by sintering.
