Walls vs. Infill for Part Strength

Adding more perimeters (walls) is almost always more efficient than increasing infill percentage.

• Visual Model: 2 Walls, 10% Infill.
• Functional Tool: 4 Walls, 30% Infill.
• Structural Load: 6 Walls, 40% Infill.

Why? Most structural stresses are carried by the outer skin of the part. Increasing walls adds material where it matters most.
