Shell + infill volume ≈ 20 cm³. Plus 10% supports = 22 cm³. Weight: 22 × 1.24 = 27g. Length: 22 / (π × 0.0875²) = 8.3m.
Inputs
Result
Higher infill for structural strength. Shell + 50% infill = ~95 cm³. Plus supports: ~105 cm³. Weight: 105 × 1.27 = 133g.
Multiply model volume by infill percentage and material density. A 30 cm³ model at 20% infill uses about 10 cm³ of PLA = ~12.4g of filament.
| Material | Density (g/cm³) | Price/kg | Strength |
|---|---|---|---|
| PLA | 1.24 | $20 | Medium |
| ABS | 1.04 | $22 | Medium-High |
| PETG | 1.27 | $25 | High |
| TPU | 1.21 | $35 | Flexible |
A 1 kg spool of 1.75mm PLA contains about 330 meters of filament. Small prints (30–50g) yield 20–30 prints. Large prints (200g+) yield 4–5 prints per spool.
Yes. 20% infill uses roughly 2x the filament of 0% infill (hollow). 100% infill uses 3–5x more than 20% infill. Wall count has a bigger impact than infill for small prints.
Diameter does not affect the amount of filament (by weight) needed. 2.85mm filament uses fewer meters but each meter weighs more. Total grams used is identical.
