Marine additiva producturing (AM) has moved well beyond desctop- printed scale models. Large- format polymer extrasion systems andd wire- arc additiva producturing (WAAM) with metal substore now produce end- use configents that are certified for installation.

Material waste reduction is one of thee most comelling economic drivers.

For a single -3meteter diameter propeller, thel material savings alonde $40,00000.

Advanced Fiber Reinforcement andComposite Producturing

Te shift from hand lay- up toautomate composite processes has redefined what is possible in marine structures. Automate fiber placement (AFP) and automate tape laying (ATL) use robotic heads to deposit carbon fiber or glass fiber tapes witch precise orientation, layer by layer, onto a mold.
