3D Printing - STL and File Preparation

If a CAD model has holes or gaps in its mesh before exporting to STL, what problem might occur?

AThe STL file will automatically fix the holes

BThe file size will be smaller than expected

CThe model will print perfectly without issues

DThe STL file may be invalid and cause print errors

Step-by-Step Solution

Solution:

Step 1: Understand mesh integrity importance
Holes or gaps cause the STL to be non-manifold, leading to errors in printing.
Step 2: Evaluate other options
STL export usually does not fix holes automatically; printing with holes causes defects; file size is unrelated.
Final Answer:
The STL file may be invalid and cause print errors -> Option D
Quick Check:
Mesh holes = invalid STL and print errors [OK]

Quick Trick: Fix mesh holes before STL export to avoid print errors [OK]
