3D Printing - STL and File Preparation
If you export an STL file with very coarse mesh settings, what is the expected impact on the printed object?
AThe print will have improved color accuracy
BThe print will be stronger due to fewer triangles
CThe print will have visible faceted surfaces and lose smoothness
DThe print will automatically correct mesh errors
Step-by-Step Solution
Solution:

  1. Step 1: Understand mesh resolution

    Coarse mesh means fewer triangles approximating surfaces.

  2. Step 2: Effect on print quality

    Fewer triangles cause visible flat facets, reducing smoothness.

  3. Final Answer:

    The print will have visible faceted surfaces and lose smoothness -> Option C

  4. Quick Check:

    Coarse mesh = faceted print surfaces [OK]
Quick Trick: Low resolution = faceted, rough surfaces [OK]
Common Mistakes:
MISTAKES
  • Assuming fewer triangles improve strength
  • Expecting color changes from mesh resolution
