3-D Printed SDV?

Would you guys trust it?

The sub called the Optionally Manned Technology Demonstrator is a 30-foot submersible made of thermoplastic resin, and it closely resembles the covert infiltration mini-subs used by the Navy SEALs. The hulls for these subs currently take three to five months to build and about $600-800,000 each. But the Naval Surface Warfare Center Carderock Division's Disruptive Technology Laboratory (DTL) partnered with Oak Ridge National Laboratory (ONRL) to bring down the expense: using ORNL's Big Area Additive Manufacturing facility, they printed the hull in six sections at a cost in the tens of thousands. A contractor assembled the sections into the final product. The whole process took weeks rather than months.
