[Solved] Why might an ASCII STL file be significantly larger than a binary STL file for the same model? — Ans: ASCII stores data as readable text, which uses more space | 3D Printing

Why might an ASCII STL file be significantly larger than a binary STL file for the same model?

AASCII STL duplicates triangles for accuracy

BASCII STL includes color and texture data

CASCII stores data as readable text, which uses more space

DBinary STL compresses the model geometry

Step-by-Step Solution

Solution:

Step 1: Compare ASCII and binary STL storage
ASCII STL stores all numbers and keywords as text, which takes more bytes than binary numbers.
Step 2: Exclude incorrect reasons
ASCII STL does not store color or duplicate triangles; binary STL is not compressed but uses compact binary format.
Final Answer:
ASCII stores data as readable text, which uses more space -> Option C
Quick Check:
ASCII STL = larger file size due to text [OK]

Quick Trick: Text format files are bigger than binary [OK]
