Abstract
A method for post-processing part obtained by additive manufacturing through sintering of a plastic powder, in order to remove particles detached from the part or partially sintered, the method including, consecutively, stripping (S1) and ionizing blowing (S2). Such a method makes it possible to remove particles having a largest dimension greater than a given dimension. The invention also relates to a corresponding manufacturing method of a plastic material part, and to a corresponding production method.
