In dual extruder printing, what is a common use of the second extruder?

ATo increase print speed by printing two layers at once

BTo cool the print faster

CTo print support material that dissolves after printing

DTo reduce filament consumption

Step-by-Step Solution

Solution:

Step 1: Understand second extruder roles
The second extruder often prints special support materials that dissolve, making complex prints easier to remove.
Step 2: Check other options
Options A, C, and D are incorrect because the second extruder does not speed printing by layers, cool prints, or reduce filament use.
Final Answer:
To print support material that dissolves after printing -> Option C
Quick Check:
Second extruder = special support material [OK]

Quick Trick: Second extruder often prints dissolvable supports [OK]
