Question

3d printing examples
select all the qualities and benefits of 3d printing that make it advantageous for
printing the complex pieces of torpedo launch systems.
creates detailed digital 3d models of the parts from cad files
allows submariners to print replacement pieces while at sea
builds large components quickly
reduces waste

Explanation:

• "Creates detailed digital 3D models of the parts from CAD files": This is more about the design phase (CAD) rather than a direct benefit of 3D printing for on - sea replacement or waste reduction for torpedo launch system parts. So it's not a correct choice.
• "Allows submariners to print replacement pieces while at sea": Submarines are at sea for long periods, and 3D printing enables them to produce replacement parts on - site, which is very advantageous for maintaining torpedo launch systems. So this is a correct quality/benefit.
• "Builds large components quickly": Torpedo launch system parts are likely complex but not necessarily large, and 3D printing is more known for complex, customized parts rather than large - scale quick building in this context. So this is not a correct choice.
• "Reduces waste": 3D printing is an additive manufacturing process, which means it only uses the material needed to build the part, thus reducing waste compared to subtractive manufacturing methods. This is a benefit for manufacturing torpedo launch system parts.

Answer:

B. Allows submariners to print replacement pieces while at sea
D. Reduces waste
