Abstract: The disclosure relates to an advanced desktop-type device that allows automatic post-processing of 3D models made by additive manufacturing process utilizing melted polymer layers to improve the quality of the final product and to improve the process parameters. A method for solvent vapor smoothing of a surface of a plastic product by: placing the plastic product to be smoothed in a closed chamber (110) with an evaporator (111) for solvent located at a bottom of the chamber (110); introducing (504) a solvent to the evaporator (111); circulating (505) solvent vapors inside the chamber (110) in a direction from the bottom to a top of the chamber (110); allowing (506) the solvent vapors to condense on the outer surface of the product; and collecting solvent vapors from the upper portion of the chamber (110).

Abstract: The present disclosure relates to a device for smoothing of 3D-printed products made by additive manufacturing process, in particular of styrene, comprising specialized modules for providing particular functions, that enables control of process parameters, including a working chamber for receiving the products to be processed. A method for solvent vapor smoothing of a surface of a plastic product by: placing the plastic product to be smoothed in a closed chamber (110) having heated walls (112-116) and an evaporator (111) for solvent; introducing (504) a solvent to the evaporator (111); allowing (506) the solvent vapors to condense on the outer surface of the product; and heating at least one wall (112-116) of the chamber (110), collecting solvent vapors from the chamber (110) and condensing the collected solvent vapors outside the chamber (110).

Abstract: The disclosure relates to smoothing of a surface of models made by additive manufacturing process utilizing melted polymer layers, by condensation of solvent vapors thereon. A method for solvent vapor smoothing of a surface of a plastic product by: placing the plastic product to be smoothed in a closed chamber (110) having heated walls (112-116) and a heated evaporator (111) for solvent; determining process parameters; heating (503) at least one wall (112-116) of the chamber (110) to a first temperature and heating the evaporator (111) to a second temperature; introducing (504) a solvent to the evaporator (111); allowing (506) the solvent vapors to condense on the outer surface of the product; and collecting solvent vapors from the chamber (110).

Abstract: A method of processing and storing control process parameters of a 3D printer is disclosed. The processed data are converted into a binary file located in the PC, and then the contents of a binary file is transferred to the printer data memory. The printer controller performs the execution of the program contained in the read-only memory of the printer controller by generating signals for printer actuators based on the numbers, in the integer form, downloaded from the data memory.
