# Filament manager: auto-track usage across every brand **Minimum Plan:** Free Automatically track filament usage as you print. Works with Bambu Lab, Creality CFS, Prusa OpenPrintTag and more NFC standards. Never run out of filament mid-print again. **Categories:** filament, organization *Effortlessly track, organize and manage your filament* ## The filament manager that tracks usage for you Give every spool its own record - brand, material, color, cost and remaining weight - then let SimplyPrint keep it accurate. As your printers print, usage is deducted **automatically**, so your inventory is always right without a scale or a spreadsheet in sight. ## One spool manager for every printer you own Whether you run one printer at home or a farm of two hundred, the filament manager keeps a live, accurate picture of what filament you have, where it is, what it cost, and how much is left. It works across every brand - Bambu Lab, Creality, Prusa, and anything else SimplyPrint supports - and ties into your print queue, statistics and slicer settings. ## Filament tracking that runs itself This is what sets SimplyPrint apart from a spreadsheet or a basic spool tracker: **usage is deducted automatically**. When you start a print through SimplyPrint, we analyze the G-code to work out exactly how much filament the job uses, convert that to grams from the spool's diameter and material density, and subtract it from the assigned spool when the print ends. Cancel or fail a print halfway and we deduct roughly half. You never touch a number. It happens in the background for every connected printer, which is why people running real workloads stop using Excel the day they switch. ## NFC tags your printer recognizes Encode a spool's data onto an NFC tag and your printer knows what's loaded the moment it's inserted. SimplyPrint reads and writes the major open standards side by side - **Creality CFS, Prusa OpenPrintTag, OpenSpool and OpenTag** - and reads **Bambu Lab** AMS tags, from your phone, your browser or a desktop USB reader. No lock-in to one brand's ecosystem. ## One filament tracker, every NFC standard Pick your printer's ecosystem - or mix and match. Every standard reads and writes from the same filament manager. ## Print labels, scan spools Generate QR-code or barcode labels for every spool and print them on a regular printer or a thermal label printer like a Dymo or Zebra. Scan a label with your phone camera, a webcam or a USB barcode scanner to pull a spool up instantly - perfect for grabbing the right spool off the shelf or checking remaining weight in seconds. ## Powered by the Open Filament Database When you add a spool, you're searching the **Open Filament Database**: an open-source, community-maintained catalog of filament that SimplyPrint stewards. Pick your brand and material and the temperatures, density and spool weights are filled in for you - the same data that links your spools to their slicing profiles. It's free, MIT-licensed, and anyone can contribute in minutes with no coding required. ## Manage filament from your phone The SimplyPrint app puts your whole inventory in your pocket. Read and write NFC tags, scan QR codes and barcodes, adjust weights, and move spools between locations - right where you store your filament. Android handles every NFC standard; iOS covers the open NDEF standards. ## Frequently asked questions ### Does filament tracking really happen automatically? Yes. For prints you start through SimplyPrint on a connected printer, we analyze the G-code to calculate how much filament the job uses and deduct it from the assigned spool when the print ends - no scale and no manual entry. You just need the spool assigned to the printer. ### Which filament brands and NFC standards are supported? Tracking works with any brand of filament. For NFC, SimplyPrint reads and writes Bambu Lab, Creality CFS, Prusa OpenPrintTag, OpenSpool and OpenTag. You can also track filament with no NFC at all using QR-code or barcode labels, or just manually. ### Do I have to use NFC or labels to track filament? No. NFC tags and labels make spools faster to identify, but the core inventory and automatic usage tracking work on their own once a spool is assigned to a printer. ### Can I import my spools from Spoolman, Spoolstock or another tool? Yes. SimplyPrint imports from Spoolman, Spoolstock, OctoPrint Filament Manager, Spool Buddy, 3D Filament Profiles and plain CSV or JSON, matching brands against the Open Filament Database as it goes. ### Does it work with the Bambu Lab AMS? Yes. For official Bambu spools with RFID tags, SimplyPrint can automatically create the spool, assign it to the right AMS slot and sync the AMS-calculated weight. Third-party filament in the AMS is assigned manually, then tracked automatically like any other spool. ### Is the filament manager free? The filament manager is included on every plan, including the Free plan. Higher plans increase certain limits, such as how many NFC tags you can write each month. --- **Learn more:** [Help Article](https://help.simplyprint.io/en/article/the-filament-manager-feature-track-organize-and-manage-your-filament-inventory-bpy529/)
