Over the last years, the significant progress of the Additive Manufacturing techniques gave rise to a great evolution in the designing method of mechanical components. This paper studies the utilization of the generative design in the redesigning of a Φ32 mm pneumatic cylinder mounting. The following mountings are considered: the Pivot bracket with rigid bearing AB7, the Clevis bracket MP2 base, and the Clevis bracket MP4 base. The main goal of mounts redesign is the weight minimization and the applicability for Fused Filament Fabrication (FFF/FDF) and Wire Laser Metal Deposition (W-LMD) Additive Manufacturing techniques. For FFF/FDM 3d printers the overhang angle is set to 45° and for W-LMD 3d printers the overhang angle is set to 25°. The generative design studies have been executed with the use of Autodesk Fusion 360 software. In order to understand the behavior of the initial models, a Finite Element Analysis has been performed. Then, the Generative Design studies were performed and the resulting structures were evaluated by using Finite Element Analysis again and comparison with the initial results. Due to the reciprocating linear motion of the pneumatic cylinder, two FE Analyses have been executed, one for the outward Stork and one for the return stork movement. From the results, it has been shown that a weight reduction by nearly 60% is feasible without significantly affecting the safety factor. Also, in comparison with initial models, the Von Mises Stress in the generative components did not increase more than 15%, while the increase of the total displacement did not exceed 20%.
