Filament DB v1.10.0

Bambu Lab NFC Spool Reading

You can now tap your Bambu Lab filament spools on the ACR1552U reader and Filament DB will automatically read them. The app detects whether a tag is OpenPrintTag or Bambu and handles both seamlessly — no configuration needed.

Bambu spool data (material type, color, nozzle/bed temperatures, weight, production date, filament length) is extracted and mapped into the same matching and import flow as OpenPrintTag. If the filament isn't in your library yet, hit "Create New Filament" and the form is pre-filled with everything from the tag.

Bambu tags are RSA-signed so they're read-only — the app shows a "read-only" badge to make this clear. OpenPrintTag read/write continues to work exactly as before.

Bed Types

A new Bed Type entity lets you define your print surfaces — Smooth PEI, Textured PEI, G10/FR4, Glass, etc. Manage them from the Settings page alongside Nozzles and Printers.

Expanded Calibrations

Calibration entries are now keyed by printer + nozzle + bed type instead of just printer + nozzle. Within each calibration you can now also store:

  • Temperature overrides — nozzle, nozzle first layer, bed, bed first layer, chamber
  • Fan settings — min speed, max speed, bridge speed

Top-level filament temperatures remain as manufacturer-recommended defaults. The per-calibration overrides are what you've actually dialed in for a specific printer/nozzle/bed combination.

The calibration API also accepts a bed_type parameter so PrusaSlicer Filament Edition can fetch bed-type-specific values.

Installed your app. Had to fight for a couple of hours before I got it up and running.
Looks very nice, will use it the comming week and come back with feedback.

 

Thanks! I've made a ton of improvements over the weekend. Please try the 1.2.0 release

Desktop + web app for managing 3D printing filament profiles

  • Filament library — store all your filament profiles with full PrusaSlicer settings (temps, retraction, pressure advance, fan curves, shrinkage compensation, etc.)
  • Per-nozzle calibrations — track extrusion multiplier, max volumetric speed, PA, and retraction per nozzle/filament combo
  • Presets — named parameter variants per filament (e.g., shore hardness profiles with different temps and EM)
  • Color variants — clone a filament as a color variant with inherited settings from the parent; override only what differs
  • Spool tracking — enter your scale reading to see remaining weight, percentage, and length in meters (computed from density and diameter)
  • PrusaSlicer import/export — batch import from INI config bundles; export all profiles as a ready-to-use INI file
  • NFC tag read/write — read and write OpenPrintTag NFC-V tags directly from the app with an ACR1552U reader (desktop only)
  • OpenPrintTag export — download .bin files compatible with the OpenPrintTag spec
  • TDS links — attach vendor Technical Data Sheet PDFs with inline preview
  • Nozzle management — define your nozzles (diameter, type, high-flow, hardened) and link calibrations to filaments
  • Search, sort & filter — find filaments by name, vendor, or type; sort by any column including remaining spool %
  • Cross-platform desktop app — macOS (Intel + Apple Silicon), Windows, Linux (x64 + arm64/Raspberry Pi)
  • Web app mode — also runs as a standard Next.js web app if you don't need NFC or a desktop wrapper

It stores: material type, temperatures, color, density, retraction settings, per-nozzle calibrations.

The data lives in MongoDB Atlas (free tier), so it's accessible from any machine. You can share a connection string  and everyone works from the same filament library.

Getting your filaments installed

There are two ways to populate the database:

  1. PrusaSlicer config bundle: Export your config bundle from PrusaSlicer and import it. All your filament profiles come in with their full settings intact.
  2. OpenPrintTag NFC tags:  Place a tagged spool on an NFC reader and the app reads it automatically. If the filament already exists in your database, it pulls it up. If it's new, you can create an entry with all the fields pre-filled from the tag.

Writing NFC tags

From any filament's detail page, you can write its data to an NFC-V tag. Place a tag on the reader, click "Write NFC," and the filament's properties are encoded to the OpenPrintTag spec and written to the tag. Stick the tag on your spool and any OpenPrintTag-compatible app or printer can read it.

You can also export the binary as a .bin file if you prefer to write tags with other software.

Hardware for NFC

 

NFC is optional — the app works fine without a reader.
