Every plastic has a characteristic density, and measuring a printed sample's mass against its volume is a quick way to sanity-check that a spool is what its label claims, or to identify an unlabeled filament.
Common filament densities
| Material | Density |
|---|---|
| PLA | ~1.24 g/cm³ |
| PETG | ~1.27 g/cm³ |
| ABS | ~1.04 g/cm³ |
| Nylon | ~1.14 g/cm³ |
| TPU (flexible) | ~1.21 g/cm³ |
| Polycarbonate | ~1.20 g/cm³ |
Worked example
A solid printed cube sample weighs 12.4g and measures 10cm³ in volume (calculated from its dimensions, accounting for infill if not solid):
Density = 12.4 / 10 = 1.24 g/cm³
This result matches PLA closely, confirming the spool's labeled material.
