Abstract
Additive manufacturing (AM) has been used in recent years as a final part manufacturing process. Nevertheless, it maintains its flexibility to produce from one-of-a-kind to recent developments for mass production. In this context, an equipment developed for pre-salt seismic data acquisition needs a hydrophone to capture data. Nevertheless the requirements and constrains of the equipment requires the hydrophone installation on a recessed grove. To install the hydrophone, the assembly team required a special tool for the shape of the hydrophone and it could not scratch the hard anodized aluminum case. The solution was to model a special tool in plastic considering additive manufacturing as the viable alternative. Thus, the torque applied to fasten the hydrophone was carefully calculated. Different tentative designs were made until reach an optimized solution. Two different AM process were considered FDM and MJF and two different materials (PA12 and ABS). The design failure criteria was defined based on the behavior of thermoplastic materials. Topology optimization was employed to avoid material waste. The final design complies with the needs of the assembly team.
