## Sparse infill density
Density usually should be calculated as a % of the total infill volume, not the total print volume.
Higher density increases strength but also material usage and print time. Lower density saves material and time but reduces strength.
Infill density determines the amount of material used to fill the interior of a 3D print. It is usually expressed as a percentage, with 100% being completely solid.
Nevertheless, **not all patterns interpret density the same way**, so the actual material usage may vary. You can see each pattern's material usage in the [Sparse Infill Pattern](#sparse-infill-pattern) section.

### Use cases
- Increasing the number of lines (e.g., 2 or 3) can improve part strength and print speed without increasing material usage.
- Fire-retardant applications: Some flame-resistant materials (like PolyMax PC-FR) require a minimum printed wall/infill thickness—often 1.5–3 mm—to comply with standards. Since infill contributes to overall part thickness, using multiple lines helps achieve the necessary thickness without switching to a large nozzle or printing with 100% infill. This is especially useful for high-temperature materials like PC, which are prone to warping when fully solid.
- Creating aesthetically pleasing infill patterns (like [Grid](#grid) or [Honeycomb](#honeycomb)) with multiple line widths—without relying on CAD modeling or being limited to a single extrusion width.

## Sparse Infill Pattern
Infill patterns determine how material is distributed within a print. Different patterns can affect strength, flexibility, and print speed using the same density setting.
There is no one-size-fits-all solution, as the best pattern depends on the specific print and its requirements.
Many patterns may look similar and have similar overall specifications, but they can behave very differently in practice.
As most settings in 3D printing, experience is the best way to determine which pattern works best for your specific needs.

### Hilbert Curve
Hilbert Curve is a space-filling curve that can be used to create a continuous infill pattern. It is known for its Esthetic appeal and ability to fill space efficiently.
Print speed is very low due to the complexity of the path, which can lead to longer print times. It is not recommended for structural parts but can be used for Esthetic purposes.
- **Horizontal Strength (X-Y):** Low
- **Vertical Strength (Z):** Normal
- **Density Calculation:** % of total infill volume
- **Material Usage:** Normal
- **Print Time:** High
- **Material/Time (Higher better):** Low

### Archimedean Chords
Spiral pattern that fills the area with concentric arcs, creating a smooth and continuous infill. Can be filled with resin thanks to its interconnected hollow structure, which allows the resin to flow through it and cure properly.
- **Horizontal Strength (X-Y):** Low
- **Vertical Strength (Z):** Normal
- **Density Calculation:** % of total infill volume
- **Material Usage:** Normal
- **Print Time:** Normal-Low
- **Material/Time (Higher better):** Normal-High

### Octagram Spiral
Esthetic pattern with low strength and high print time.
- **Horizontal Strength (X-Y):** Low
- **Vertical Strength (Z):** Normal
- **Density Calculation:** % of total infill volume
- **Material Usage:** Normal
- **Print Time:** Normal
- **Material/Time (Higher better):** Normal-Low
