1. A method of post-treatment of a part obtained by additive manufacturing by sintering of a powder of a plastic material, for the elimination, an at least partially sintered part, of the particles detached from said part or that are partially sintered, the method comprising successively:
stripping (S1), thereby obtaining a stripped part; and
ionizing blowing (S2) of the stripped part, comprising blowing ionized air onto the part;
wherein the stripping is performed in a rotary barrel; and
the ionizing blowing is performed with two ionizing bars, one ionizing bar being positioned inside said rotary barrel and another ionizing bar being disposed outside said rotary barrel.
