The invention relates to a method for analyzing evaporation fumes (7) emitted during the implementation of an additive manufacturing process employing at least one chemical species as a fusible material, the analysis method comprising the following steps: - emitting at least one beam (23) of X-rays to irradiate at least a portion of the evaporation fumes (7) emitted during the implementation of the additive manufacturing process; - detecting, by a detector (24), fluorescence photons emitted by the at least a portion of the evaporation fumes (7) irradiated by the at least one beam (23) of X-rays, and generating a detection signal representative of the energy deposited by the fluorescence photons in the detector (24); and - identifying, from the detection signal, all or some of the chemical species present in the evaporation fumes (7).
