3D Printing - Support Structures

AThreshold set too low, causing supports on gentle slopes

BThreshold set too high, causing no supports at all

CPrinter nozzle temperature is too low

DLayer height is too large

Step-by-Step Solution

Solution:

Step 1: Understand effect of low threshold
A low threshold like 30° means supports are added even on mild overhangs, increasing material use.
Step 2: Identify cause of excessive supports
Excessive supports indicate the threshold is too low, triggering supports unnecessarily.
Final Answer:
Threshold set too low, causing supports on gentle slopes -> Option A
Quick Check:
Low threshold = more supports [OK]

Quick Trick: Low angle threshold causes too many supports [OK]
