Abstract:
1. A filtering body, extending about an axis of rotation and having a first axial face and a second axial face opposite to said first axial face, the filtering body comprising: a filtering net formed by a plurality of filaments that define a plurality of pores therebetween; a frame defined by non-porous solid elements, said frame and said filtering net extending about said axis of rotation forming an inner radial surface facing said axis of rotation and an outer radial surface opposite to said inner radial surface, and said inner radial surface being connected to said outer radial surface by said first axial face and said second axial face; wherein, when considering diametrical sections of said filtering body, at least some of said plurality of filaments extend from said first axial face up to said second axial face along respective longitudinal axes that are parallel, and wherein said longitudinal axes form an inclination with respect to said axis of rotation, wherein said frame and said filtering net are formed in one piece in an additive manufacturing technique.
