Filament reference
Empty spool weight database
A deliberately conservative reference list for estimating remaining filament. Every published tare weight includes its source quality.
| Brand | Spool | Empty weight | Source quality | Source |
|---|---|---|---|---|
| Bambu Lab | Reusable spool (1 kg filament) | 250 g | Manufacturer source | Bambu Lab Filament Guide |
| eSUN | Transparent spool (1 kg filament) | 220 g | Manufacturer source | eSUN eBOX User Guide |
| eSUN | Black spool (1 kg filament) | 230 g | Manufacturer source | eSUN eBOX User Guide |
| eSUN | Transparent spool (0.5 kg filament) | 203 g | Manufacturer source | eSUN eBOX User Guide |
| eSUN | Black spool (0.5 kg filament) | 212 g | Manufacturer source | eSUN eBOX User Guide |
| Overture | Standard spool (1 kg filament) | 147 g | Manufacturer source | Overture filament wiki |
| Prusament | Plastic spool (1 kg filament) | 201 g | Manufacturer source | Prusa Knowledge Base |
| Prusament | Cardboard spool (1 kg filament) | 184 g | Manufacturer source | Prusa Knowledge Base |
| Prusament | Plastic spool (2 kg filament) | 350 g | Manufacturer source | Prusa Knowledge Base |
This database starts small on purpose. Makeratory does not publish an uncertain forum estimate as though it were a manufacturer specification. More spool variants will be added as they can be sourced or verified.
Use a tare weight
Once you know the empty weight of your spool, use it with the current loaded weight to estimate how much filament remains.
