DEVICE FOR OBTAINING ARTICLES FROM HIGH-TEMPERATURE POLYMERS BY SELECTIVE LASER SINTERING Russian patent published in 2020 - IPC B22F3/105 B29C64/141 B29C64/20 B33Y30/00 

FIELD: manufacturing technology.

SUBSTANCE: invention relates to production of articles from powder of high-temperature polymers by selective laser sintering. Device comprises laser-optic assembly, separated from it by ZnSe-glass inner tight chamber with pyrometer and powder heating system, a working table built into the powder layers application plate, a lower transition table with a vertical movement drive, a powder leveling mechanism, a ZnSe-glass cooling circuit on the side of the internal sealed chamber, a rod for moving the lower transition table, water cooling circuits of the application plate of the powder layers, the rod for movement of the lower transition table, the plate of the clamping device of the replaceable production bin, the pyrometer housing and the flange of the glass-optic unit glass, on which the protective ZnSe-glass is installed. Cooling circuits are made in the form of a system of interconnected flexible and rigid tubes, which supply cooling medium from the hydraulic system to zones of location of corresponding devices.

EFFECT: possibility of varying temperature in sealed chamber in a wide range due to additional cooling circuits.
