AMS Integration
Your printer tells us what you're using. We track it.
Load a spool into your AMS, and Spooldex detects it automatically via MQTT. RFID-tagged spools get matched instantly. Unknown spools get created in your inventory. No manual entry, no spreadsheet — your shelf stays accurate print after print.
- Auto-detects AMS tray changes in real time
- RFID matching links physical spools to your inventory
- Unrecognized spools get auto-created so nothing falls through the cracks
Print History & Cost
Know exactly what each print costs.
Every print gets logged with gram usage per spool, calculated cost, and a full tray-by-tray breakdown. See your cost per print, per spool, or per kilogram — normalized so you can compare brands and materials without mental math.
- Per-print cost calculated from spool price and grams used
- Price-per-meter normalization across brands and materials
- Full print history with timestamp, duration, and material breakdown
Multi-Color Support
Multi-color prints? We track every spool.
Four-color prints don't confuse the tracking. Spooldex logs per-tray attribution for each print, showing exactly which spool contributed how many grams. Color swatch breakdowns give you a visual at a glance.
- Per-tray gram attribution for multi-material prints
- Color swatch pie charts show material distribution
- Supports up to 4 AMS trays per print job
Smart Inventory
Your shelf, organized.
Filter by color family, sort by remaining percentage, check price tags at a glance. Archive finished spools instead of deleting them so your history stays intact. Spooldex treats your inventory like it matters — because it does.
- Color family filters to find the right spool fast
- Remaining weight as percentage and grams
- Archive vs. delete — keep your history, clean your shelf
More built in
Everything else you'd expect. And a few things you wouldn't.
Live Printer Dashboard
See your printer in real time. Nozzle and bed temperatures, AMS humidity readings, print progress, and printer status — all streamed via SSE. No manual refresh needed.
Barcode Scanning
Scan. Match. Track. Point your camera at a spool's barcode and Spooldex looks up the EAN, matches it to a catalog entry, and adds it to your inventory. From box to shelf in seconds.
Built for Bambu Lab owners
Because filament management shouldn't be a second job.
Spooldex integrates directly with Bambu Lab's ecosystem via MQTT and Bambu Cloud. It works with your P1S, X1C, A1, and H2S — any printer with an AMS. Track 5 spools across 2 AMS units, or 16 across a full multi-printer setup. It just works.
Works with your AMS
P1S, X1C, A1 Mini, H2S — any Bambu printer with an AMS. Tray detection is automatic.
Bambu Cloud sync
Connect once, and print jobs get logged automatically. No copy-pasting from the slicer.
Brand-agnostic filament
Bambu-first doesn't mean Bambu-only. Track Polymaker, Prusament, eSUN, or any brand on your shelf.
Your filament, finally under control.
Set up in minutes. Connect your Bambu printer. Let Spooldex handle the tracking so you can focus on what actually matters — printing.
