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 based on 3D printing benefits for torpedo launch system parts:

1. “Creates detailed digital 3D models of the parts from CAD files”: 3D printing starts with creating/using digital 3D models from CAD, but this is more about design (not a direct benefit of printing the part). Eliminate.
2. “Allows submariners to print replacement pieces while at sea”: 3D printing enables on - demand manufacturing. Submarines at sea can’t easily get replacement parts, so printing on - site is a key benefit. Select.
3. “Builds large components quickly”: 3D printing is slower for large components (vs traditional methods) and complex torpedo parts may not be “large” in a way 3D printing excels at speed. Eliminate.
4. “Reduces waste”: 3D printing is additive (builds layer - by - layer), so it produces less waste than subtractive manufacturing (cutting from a block). This is a core benefit. Select.

Answer:

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