3D Printing - Slicer Software Basics

AThey used a solid infill pattern instead of honeycomb

BThey used too high infill density

CThey set the print speed too high

DThey forgot to set a shell thickness, so only the outer walls print

Step-by-Step Solution

Solution:

Step 1: Analyze 0% infill effect
0% infill means no internal material, so strength depends only on outer walls (shells).
Step 2: Identify missing shell thickness
If shell thickness is too thin or not set, the print will be fragile despite 0% infill.
Final Answer:
They forgot to set a shell thickness, so only the outer walls print -> Option D
Quick Check:
0% infill + thin shell = fragile print [OK]

Quick Trick: 0% infill needs strong shells to avoid fragility [OK]
