Abstract
The invention relates to a process and an apparatus for chemical smoothing of a plastic part () produced by selective layerwise consolidation of a construction material. The process comprises the steps of: temperature-controlling the plastic part to a first temperature; temperature-controlling solvent vapour () comprising a solvent to a second temperature; subjecting the plastic part () to the solvent vapour () temperature-controlled to the second temperature for a particular duration, wherein the subjecting of the plastic part () to the solvent vapour () has the result that an outer layer of the plastic part () is liquefied; and discharging at least a portion of the solvent vapour () after the particular duration, wherein the plastic part () is stationary from commencement of the temperature-controlling of the plastic part until termination of the discharging of the solvent vapour ().
