# The Open Filament Database: contributing and using preset data

# The Open Filament Database: contributing and using preset data

When you add filament in SimplyPrint, you'll notice brand presets with pre-filled temperatures, densities, colors, and spool weights. This data comes from the **Open Filament Database** - an open source, community-maintained collection of filament information.

## What is the Open Filament Database?

The Open Filament Database is a collaborative project hosted by the [Open Filament Collective](https://github.com/OpenFilamentCollective). It contains detailed information about filament brands, their material lines, colors, and technical specifications.

When you select a known brand and product in SimplyPrint's Filament Manager, all this data is automatically filled in:

- **Brand name and logo**
- **Material type** (PLA, PETG, ABS, etc.)
- **Color name and hex code**
- **Nozzle and bed temperatures**
- **Material density** (for accurate weight calculations)
- **Spool weight** (empty spool weight for weighing)

This saves you from manually entering specifications and ensures accurate filament tracking.

## Using the database in SimplyPrint

The database is built into SimplyPrint - you don't need to do anything special to use it.

When adding a new spool:

1. Start typing a brand name in the **Brand** field
2. Select from the autocomplete suggestions
3. Choose the **Material line** (e.g., "PolyLite", "Galaxy", "Matte")
4. Select the **Color**
5. All technical specifications are filled in automatically

If a brand or material isn't in the database, you can still add it manually - your custom entries are saved for future use.

You can contribute:
