2026 3D Print Filament Density, Spool Length & STL Polygon Reference Table
2026 Verified ReferenceCalculate 3D print filament weight by multiplying your mesh's effective volume (outer shell volume + infill percentage) by the material density in `g/cm³`: PLA is `1.24 g/cm³`, PETG is `1.27 g/cm³`, and ABS is `1.04 g/cm³`. Keep binary STL files under 250,000 triangles (`0.01 mm` chordal tolerance) to prevent slicer G-code stuttering.
Weight (g) = Mesh_Volume_cm3 × (Shell_Ratio + Infill_Ratio × (1 - Shell_Ratio)) × Density_g_cm3| 3D Printing Material | Density (g/cm³) | 1kg Spool Length (1.75mm) | Nozzle / Bed Temp & Slicer Note |
|---|---|---|---|
| PLA / Tough PLA+ | 1.24 g/cm³ | ~335 meters | 200–215°C / 60°C Bed | 100% Cooling Fan |
| PETG (Chemical/UV Resistant) | 1.27 g/cm³ | ~327 meters | 235–245°C / 75°C Bed | 30%–50% Fan, Dry <20% RH |
| ABS / ASA (High-Temp Enclosure) | 1.04 – 1.07 g/cm³ | ~388 – 400 meters | 250–265°C / 105°C Bed | Enclosed Chamber Required |
| TPU 95A (Flexible Elastomer) | 1.21 g/cm³ | ~343 meters | 220–230°C / 50°C Bed | Direct Drive ≤ 45 mm/s |
| PA-CF / PET-CF (Carbon Fiber) | 1.15 – 1.30 g/cm³ | ~320 – 360 meters | 275–300°C | Hardened Steel 0.4mm/0.6mm Nozzle |
| SLA / MSLA 405nm UV Resin | 1.10 – 1.18 g/cm³ | ~880 mL per 1kg bottle | Hollow to 2.0mm wall + add 2 drain holes + 18% support |
