Infill 이는 여러 대안을 비교하고, 한계를 확인하며, 위험이 적은 공정을 선택해야 할 때 유용한 공학적 주제입니다.
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
- 무게 감소: Varies density without proportional strength loss
- Material savings: Reduces print cost and time
Production applications benefit significantly from optimized infill.
Pattern Comparison
Honeycomb (Hexagonal)

- Excellent strength-to-weight ratio
- Even stress distribution
- Medium print time
- Good for most applications
가장 적합한 대상: General-purpose functional parts
Glass-filled materials pair well with honeycomb.
Gyroid
특성:
- Superior isotropic strength (equal in all directions)
- Good vibration damping
- Slightly longer print time
- Excellent for load-bearing parts
가장 적합한 대상: Parts with multi-directional loads
Cubic
특성:
- Good strength, slightly anisotropic
- Fast printing
- 인쇄하기 쉬움
- Good for standard applications
가장 적합한 대상: Quick prototypes, non-critical parts
Triangular

- Fast printing
- Good for specific load cases
- Directional properties
가장 적합한 대상: Parts with known load direction
Grid/Rectilinear
특성:
- Fastest printing
- Lowest material usage
- Weakest structure
- Good for non-structural parts
가장 적합한 대상: Display models, light-duty applications
Lightning
특성:
- Minimal material usage
- Fast printing
- Weak structure
- Automatic density adjustment
가장 적합한 대상: Top surface support only, not structural
