Question

true or false? select all the statements that are true based on what was presented in the copper manufacturing video. glue is injected into copper powder. a printed copper part is not yet as strong as a machined copper part. tiny pockets of air in the copper part increase performance. williams says the product will be ready for widespread use within five years.

Explanation:

To solve this, we analyze each statement based on typical copper manufacturing (likely additive manufacturing like 3D printing) knowledge:

1. Glue is injected into copper powder: In binder jetting (a 3D printing method for metals), a binder (similar to glue) is used with metal powder. So this is likely True.
2. A printed copper part is not yet as strong as a machined copper part: Additively manufactured parts often have slightly different (sometimes lower initially) strength vs. machined parts due to microstructural differences. So this is likely True.
3. Tiny pockets of air in the copper part increase performance: Porosity (air pockets) in metal parts usually decreases performance (weaker, less dense). So this is False.
4. Williams says the product will be ready for widespread use within five years: Without the video, but if the video mentions a 5-year timeline for adoption, this could be True. However, based on common knowledge, the first two are more reliably True (assuming standard additive manufacturing context for copper).

Answer:

(Assuming the first two are True based on typical copper manufacturing via additive processes):

• Glue is injected into copper powder (True)
• A printed copper part is not yet as strong as a machined copper part (True)

(Note: The third is False, and the fourth depends on the video. If the video confirms the fourth, include it; otherwise, focus on the first two as more universally true for copper additive manufacturing.)
