Why does additive manufacturing often result in less material waste than subtractive manufacturing?

ABecause it adds only the material needed layer by layer

BBecause it melts all material into a block

CBecause it cuts away excess material precisely

DBecause it uses molds to shape material

Step-by-Step Solution

Solution:

Step 1: Compare additive and subtractive methods
Additive builds objects by adding material only where needed; subtractive removes material from a block.
Step 2: Understand waste generation
Subtractive creates waste by cutting away material; additive minimizes waste by layering precisely.
Final Answer:
Because it adds only the material needed layer by layer -> Option A
Quick Check:
Less waste reason = adds only needed material [OK]

Quick Trick: Additive adds only needed material, reducing waste [OK]
