Infill pattern selection affects print strength, weight, speed, and material usage. While many users stick with default settings, understanding pattern characteristics helps optimize prints for specific applications.
Why Infill Pattern Matters
Infill serves multiple purposes:
- Structural support: Provides internal strength
- Top surface support: Prevents sagging on flat surfaces
- Снижение веса: Varies density without proportional strength loss
- Material savings: Reduces print cost and time
Применение в производстве benefit significantly from optimized infill.
Pattern Comparison
Honeycomb (Hexagonal)
Характеристики:
- Excellent strength-to-weight ratio
- Even stress distribution

- Superior isotropic strength (equal in all directions)
- Good vibration damping
- Slightly longer print time
- Excellent for load-bearing parts
Лучшее для: Parts with multi-directional loads
Cubic
Характеристики:
- Good strength, slightly anisotropic
- Fast printing
- Easy to print
- Good for standard applications
Лучшее для: Quick prototypes, non-critical parts
Triangular
Характеристики:
- High strength in specific directions
- Fast printing
- Good for specific load cases
- Directional properties
Лучшее для: Parts with known load direction
Grid/Rectilinear
Характеристики:
- Fastest printing
- Lowest material usage
- Weakest structure
- Good for non-structural parts
Лучшее для: Display models, light-duty applications
Lightning
Характеристики:
- Minimal material usage
- Fast printing
- Weak structure
- Automatic density adjustment
Лучшее для: Top surface support only, not structural
