Desktop device and a method for postprocessing of a plastic product

摘要

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).
