PLANT FOR POWDER LASER STEREOLYTHOGRAPHY Russian patent published in 2007 - IPC B22F3/105 B23K26/00 

FIELD: laser technology, namely apparatuses for producing three-dimensional articles by selective laser sintering of powder materials.

SUBSTANCE: plant includes laser apparatus with optical system; manufacturing platform for placing sintered blank; attachment for feeding powder to working space over manufacturing platform; apparatus for monitoring and sustaining predetermined thickness of powder layer. Optical system is made with possibility of horizontal motion along two mutually normal directions. Manufacturing platform is mounted with possibility of vertical motion. Monitoring apparatus includes vibrator, pickup for monitoring level of surface of powder layer and unit for compensating level of powder layer surface. Said compensating unit is mounted between walls of manufacturing platform and housing with possibility of vertical motion by means of drive device regardless from drive unit of manufacturing platform. Space restricted by lateral walls of manufacturing platform, housing and by end surface of compensating unit is communicated with attachment for feeding powder. Vibrator, pickup for monitoring surface level of powder layer and member of drive of compensating unit are connected with control unit.

EFFECT: possibility for producing high-quality articles with predetermined set of operational properties.
