3D Submarine test bench is designed to offer a wide range of challenging geometric features for 3D printers and touch on different issues related to additive manufacturing.

The 3D model is designed to print at a 1:1 scale without support materials. It's challenging for most 3D printers, but the small volume typically prints in less than two hours and doesn't require much material.

The different surfaces of the model reveal typical issues related to surface finish, model accuracy, deformation, etc.
