DEVICE FOR AUTOMATED FINISHING OF PRODUCTS MADE WITH 3D PRINTING Russian patent published in 2017 - IPC B29C71/02 B29C67/02 B29C64/40 B33Y10/00 

FIELD: technological processes.

SUBSTANCE: device for automated finishing of products made with 3D printing, including a working chamber with a smoothing sample placed in it, connected to the reactor with the possibility of feeding and circulating solvent vapor, a storage tank for liquid solvent, and a heater and a refrigerator with the possibility of evaporation and condensation of the solvent, and a control unit. Herewith the heater and the solvent cooler are structurally combined in one unit, which is made in the form of a thermoelectric converter based on the Peltier effect. The working chamber can be provided with a steam supply channel at the top of the working chamber and a circulation channel at the bottom of the working chamber. In the latter, a fan, temperature and steam concentration sensors are installed. The side walls of the reactor can be provided with a heat-insulating coating, and the thermoelectric converter plate-the Peltier element-and the temperature sensor are connected to the bottom of the reactor with one side. And the second side of the Peltier element is connected to the radiator equipped with a fan. In the lower part of the reactor, a supply and evacuation tube is introduced, connected through a reversible metering pump to a container for storing the liquid solvent. The control unit may comprise a microcontroller connected to temperature, concentration, fans and a stepper motor of a reversible metering pump.

EFFECT: increasing the degree of automation of the smoothing process and reducing the power consumption.
