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:

To solve this, we analyze each option:

1. "Creates detailed digital 3D models of the parts from CAD files": This is more about CAD modeling (pre - 3D printing design) rather than a benefit of 3D printing for torpedo launch system parts. So this is not a correct choice.
2. "Allows submariners to print replacement pieces while at sea": 3D printers can be deployed on submarines, enabling on - demand printing of replacement parts during a mission at sea. This is a key benefit for maintaining complex systems like torpedo launch systems in a maritime, remote environment.
3. "Builds large components quickly": 3D printing, especially for complex geometries, may not be faster than traditional manufacturing for large components. Also, torpedo launch system parts may not all be large, and speed for large components is not a primary advantage here. So this is not a correct choice.
4. "Reduces waste": 3D printing is an additive manufacturing process, where material is added layer - by - layer. This contrasts with subtractive manufacturing (like machining) which cuts away from a larger block of material, resulting in significant waste. Reducing waste is a major benefit, especially for complex, custom parts of torpedo launch systems.

Answer:

• Allows submariners to print replacement pieces while at sea
• Reduces waste
