1. A method of manufacturing at least a part of a suppressor, wherein the suppressor includes an outer housing defining an internal cavity, the outer housing having an end wall and at least one sidewall, an outlet in the end wall for a bullet to exit the suppressor, a plurality of baffles provided within the internal cavity and spaced apart from the side wall, an inner wall connecting at least a pair of the baffles, and at least one fin connected to at least one of the side wall and the inner wall,
wherein the method comprises manufacturing the part of the suppressor using selective metal melting by:
a. depositing a starter material onto a substrate;
b. melting the starter material to form a layer of the part of the suppressor; and
c. repeating steps (a) and (b) in a build direction so as to form the at least one side wall, the plurality of baffles, the inner wall and the at least one fin within the internal cavity, with the at least one side wall, the baffles, the inner wall and the at least one fin monolithically formed together in a monocoque structure.
