medium📝 Analysis Q13 of 15
Step-by-Step Solution
Solution:
Step 1: Analyze overhang angle effect
Overhangs above 45 degrees usually require supports. Reducing angle to 30 degrees makes it self-supporting.Step 2: Evaluate other options
Making overhang vertical removes overhang but may change design; hollow cavity doesn't support overhang; thickness increase doesn't remove need for support.Final Answer:
Change the overhang angle to 30 degrees -> Option DQuick Check:
Overhang < 45° = less supports [OK]
Quick Trick: Lower overhang angle below 45° to reduce supports [OK]
Common Mistakes:
- Thinking hollow cavities support overhangs
- Assuming thicker parts need no supports
- Believing vertical overhangs don't affect supports
