Device and a method for solvent vapor smoothing of a surface of a plastic product

摘要

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).
