Common Questions
- What is infill in 3D printing?
- What infill percentage should I choose?
- Does higher infill make parts stronger?
- Does infill increase price?
Simple Explanation
Infill is the internal structure inside a 3D printed object.
It controls how strong, heavy, and expensive the part will be.
Instead of printing a solid object, the printer fills the inside with a pattern structure.
Typical Infill Settings
| Infill % | Use Case |
|---|---|
| 10–15% | Decorative models |
| 20–30% | Most common prints |
| 40–60% | Strong functional parts |
| 80–100% | Maximum strength |
How It Affects Price
Higher infill:
- Uses more filament
- Takes longer to print
- Costs more
Lower infill:
- Cheaper
- Faster printing
- Lighter parts
Quick Tip
For most parts, 20% infill is perfect..
