Method and device for smoothing elements made using the SLS incremental technology (Selective Laser Sintering) of materials based on polyamide powder - PA. The method consists in that the element is subject to effects of vapours of a chemical compound from the following group: formic acid, acetic acid, m-creozol, acetic anhydride, so that the applied chemical compound, in atmospheric pressure, is brought to a temperature above its specific boiling point for a time of 1-350 seconds, counting from the moment when vapours of the chemical compound condensate on the processed prototypical element. The device has a chamber (3) with working space, below which there is a container of the active substance dispenser and heating element (6), separated from the working space with the movable screen (7), and vapour extraction system (8) with ventilation duct. |
