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
- Gewichtsvermindering: Varies density without proportional strength loss
- Material savings: Reduces print cost and time
Production applications benefit significantly from optimized infill.
Pattern Comparison
Honeycomb (Hexagonal)
Kenmerken:
- Excellent strength-to-weight ratio
- Even stress distribution
- Medium print time
- Good for most applications
Meest geschikt voor: General-purpose functional parts
Glass-filled materials pair well with honeycomb.
Gyroid

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

Material costs should factor into pattern selection.
FAQ
When is Infill Patterns Explained — Strength, Speed & Material Usage Compared a good option?
Infill Patterns Explained — Strength, Speed & Material Usage Compared is a good option when fast iteration, complex geometry, low tooling cost, or low-volume production is more important than molded-part unit cost.
What should be checked before choosing Infill Patterns Explained — Strength, Speed & Material Usage Compared?
Controleer de onderdeelgrootte, materiaaleigenschappen, oppervlakteafwerking, maattolerantie, blootstelling aan hitte, belastingsrichting en of nabewerking nodig is.
How does Infill Patterns Explained — Strength, Speed & Material Usage Compared compare with CNC machining?
Met 3D-printen kunnen complexe vormen snel worden gemaakt, terwijl CNC-bewerking vaak sterker is voor precieze oppervlakken, nauwere toleranties en productiematerialen.
What affects the cost of Infill Patterns Explained — Strength, Speed & Material Usage Compared?
De kosten zijn afhankelijk van het materiaal, het bouwvolume, de printtijd, de laaghoogte, het verwijderen van de ondersteuning, de afwerking, de inspectie en het aantal onderdelen in de bouw.
