The default behavior of this website is to prioritize local data storage.
Unless you explicitly enable the Cloud Sync feature, all of your inventory data, custom filaments, and user preferences are stored exclusively in your browser's local storage. This means your data never leaves your device and is not accessible to anyone else.
If you choose to create an account and enable Cloud Sync, your inventory and custom filament data are uploaded to a secure cloud database (Firestore).
To ensure maximum privacy, all synced data is encrypted using AES (Advanced Encryption Standard) on your device before it is sent to the server. This means the data stored in the cloud is unreadable without your account's unique security key.
To improve the functionality of the website, generic usage statistics are collected.
The site logs non-specific information about how features are used (e.g., when a page is viewed or a specific tool is accessed), such as event names.
The data collected for analytics does not include your name, or the specific details of your 3D printing inventory.
Your privacy is a priority, and your data is treated as your own.
At no point will any of the data collected—whether generic usage stats or encrypted sync data—be sold, traded, or shared with third-party companies.
Your email address (if provided for Cloud Sync) will only be used for account-related functions, such as password resets. It will never be used for marketing or promotional purposes.
You maintain full control over your information:
You can delete your local data at any time by clearing your browser's cache and local storage.
If you use the Cloud Sync feature, you can log out at any time, which stops the synchronization process on that device, retaining your data on your device. If you would like your synced cloud data deleted, please contact support (support@bambutracker.com).
Users have the ability to log out of all active sessions across different devices to ensure their account remains secure.

Filament Tracker is a web app for managing your 3D printing filament inventory. It shows real-time stock availability from Bambu Lab stores worldwide, tracks your owned filaments, and helps you manage what you have and what you need.
Use the sidebar on the left to check/uncheck filament types. Quick selection buttons:
Click the status pill in the top-right corner of any filament card. It cycles through three states:
Tip: Long press (hold) a Wishlist pill to quickly remove it from your wishlist. The pill will fill red from left to right — release after it completes to confirm.
The dots next to each filament type indicate your ownership:
Click Tools & Settings at the bottom of the sidebar, then go to the Help tab and click "Show Interactive Guide". The tour will walk you through all the main features step by step.
Open Tools & Settings > Settings and use the Display Theme button. The app cycles between Auto, Light, and Dark. Auto follows your device preference.
On mobile layouts, enable Compact Cards in the top bar to switch to a denser layout. Each compact card shows quick status indicators and the filament image only; tap the image to open full details in a modal card.
On larger mobile/tablet widths, compact cards use fixed-width columns for better space usage while keeping the same actions.
Compact mode supports the same actions as full cards, including status changes, Buy More, Print Status, and inventory updates.
When a filament is marked as Owned, an inventory panel appears at the bottom of the card with:
The 🛒 shopping cart icon on owned filament cards marks them as "Buy More". When active 🛒, it adds the filament to your Wishlist / Buy More filter, making it easy to track which owned filaments need restocking.
Enable min / max stock counters in Tools & Settings > Settings. Each owned filament card will then show Min and Max controls on the same row. Min compares your total remaining spool-equivalent stock against the minimum you set.
If a filament drops below that minimum, it is automatically flagged for Buy More and can be filtered with Status Filter > Below Min Levels. Max is a planning target for how much stock you want to keep on hand.
The 🖨 printer icon on owned filament cards lets you mark filaments as:
Use the To Print / Loaded filter to see all filaments with these statuses.
Tip: Long press the print-status icon to step backwards: Loaded → To Print, or To Print → Unloaded. Unloaded has no long-press action.
Each filament card shows availability badges:
The colored bars next to badges show stock history over the last 30 days (green = in stock that day).
Toggle the Out of Stock switch in the filter bar to switch between:
When Bambu Lab discontinues a filament color (no longer available in the store), it becomes "Archived". Archived filaments show an "Archived - Not in store" label, but you can still track your existing inventory for these colors. If you want to remove an archived filament from your view, you can delete it using the button on the card.
When you decrement a Full Spool or Refill, the app will ask if you want to "open" it. You have two choices:
This saves you the manual step of decrementing stock and then separately adding an open spool with the correct weight.
Use the dropdowns in the top bar:
To clear a filter quickly, open the dropdown and choose All ....
Yes. The app keeps filter state in the URL (search, status, colour groups, and locations), so you can bookmark or share your current view. Status selections are also saved locally and restored automatically when no status filter is provided in the URL.
When status filters are active, cards you just edited can stay visible so you can finish related actions without losing context. If you prefer the old behavior, enable Always auto-apply filter changes in Tools & Settings > Settings > Filter Behavior.
The search box matches against:
Use the Sort by dropdown to add sort conditions. You can:
Available sort options: Type, Status, Name, Brand, Colour Group, ETA Back in Stock, Inventory Weight Asc, and Inventory Weight Desc.
Use the Bambu Store dropdown in the top bar. Available regions include US, EU, UK, AU, JP, and more. Stock availability varies by region.
Click +Add Custom Item in the sidebar. Fill in:
When you select an accessory-style type (for example Accessories, Hotends, or Build Plates), the modal switches to accessory mode: color controls are hidden, the group defaults to Other, and inventory uses a single Qty counter.
You can add multiple purchase links for a custom item, open them from the Custom card badge, save a note from the note icon on the card, and use Save and Add More to keep the same supplier and type while starting the next item immediately.
Click the pencil icon on any custom card (filament or accessory). This opens the edit modal where you can modify details or delete the item. Use the copy icon next to it to duplicate an existing custom item into a new draft without re-entering everything from scratch.
Yes! Go to Tools & Settings > Settings and scroll to Custom Filament Types. You can add types like "PLA Pro" or "PETG-CF" to any material group. These will appear in filters and dropdowns.
Enable this in Settings to track weight on multiple open spools of the same filament. Perfect for using up leftover filament from different projects.
When enabled, each filament card shows a summary of your open spools. You can also enable "Show full spool details on cards" in Settings to display all individual open spool weights directly on the card instead of a summary.
If you prefer counts instead of grams, enable Use simple open spool counter (no weights) in Settings.
You can also choose how open spool weights are entered. In Settings, use Open spool weight control to change slider granularity, or set it to 0 to switch to direct number-entry boxes.
Enable in Settings to track where each spool is stored. You can:
Smarter Decrementing: When you decrement a spool or refill that has multiple items with locations assigned, the app will ask you which specific item/location you want to remove from, so you always know exactly what's being changed.
You can also enable "Show full location details on cards" in Settings to display all location assignments directly on the card instead of a summary.
If you prefer faster location entry for full stock, enable Use Bulk Locations for spools and refills. That mode lets you assign counts per location for full spools and refills, while open spools continue to use individual rows.
Click Upload 3MF in the sidebar to upload a Bambu Studio project file. The app will:
Note: This is experimental. Accuracy depends on hex color data in your filaments.
Use Scan Bambu Label from the sidebar to capture or upload a photo of an official Bambu Lab filament side label, then review the detected match before adding stock to your inventory.
The 3MF Library lets you save uploaded 3MF projects for future reference. After uploading a 3MF file and selecting your filaments, click Save to Library to store the project. Access your library at any time using the View Library button in the sidebar.
You can choose an image embedded in the 3MF file (if available) as the project's thumbnail when saving to the library. The app caches this locally first for fast display, then uploads/syncs in the background for cloud accounts.
You can click library images (card thumbnails and project thumbnail previews) to expand them in the full-screen image viewer.
The Library shows each project's status at a glance:
Each required filament can also store a required grams value, so the library can flag projects where you own the right colour but not enough material. Slot-number badges are shown in project views to make multi-slot matching easier.
You can organise projects with Categories (manage them in Settings), add notes, and filter by status. Use the "In Library" status filter on the main grid to see which filaments appear in your saved projects. This tracking is now always enabled by default (no separate toggle required).
Use the library grouping selector to switch between Group: Category and Group: Least Colour Changes, and watch for loaded badges in filament indicators when required filaments are currently loaded.
Categories are sorted alphabetically, and if a category is deleted, affected projects are automatically moved to Unassigned.
Open Tools & Settings > Tools to see Filament Stats. It summarizes your owned filament by brand and type, plus approximate value and full-price totals using the pricing data from the currently selected store region.
The app includes official Bambu Lab printers and accessories alongside filaments. You can track which printers and accessories you own using the same status and inventory controls as filaments.
To filter accessories by compatibility:
If no printers are selected, all accessories are shown. Printers and accessories appear under the Other group in the sidebar.
Cloud Sync (for supporters) keeps your inventory synchronized across devices in real-time. Your data is encrypted before upload. Set up in Tools & Settings > Account.
Yes. If you're signed into a Cloud Sync account, open Tools & Settings > Account and enable Opt out of test-environment email notifications. This preference is saved to your account.
By default, all data is stored locally in your browser. This means:
For a local backup file, go to Tools & Settings > Tools and click Export Backup. This downloads a .json file with your inventory, preferences, custom items, library data, and settings.
If Cloud Sync is enabled, you can also open Cloud Backup & Restore from the same Tools tab to create encrypted cloud backups manually or turn on automatic daily cloud backups.
For a local .json backup, go to Tools & Settings > Tools and click Import Backup. Select your backup file. You can choose to:
For cloud backups, open Cloud Backup & Restore, choose a backup, and click Restore. The app emails you a 6-digit restore code, creates a pre-restore safety backup, and then refreshes the app view once the restore completes.
Automatic cloud backups are cleaned up automatically to keep the list manageable:
Use Bulk Import from CSV in Tools when you want to import many rows from a spreadsheet at once. You can download the template directly in the import flow.
If you've copied filament info from an order or spreadsheet, use Bulk Import from Text in Tools. It parses common formats and matches them to official Bambu filaments.
The expected format matches line items shown in your Bambu Lab store account order details, so copy/paste from that view should import correctly.
For extra examples and tips, see the official Facebook page linked in the import modal and contact section.
Click Export Owned/Wishlist as CSV in Tools to download a spreadsheet-compatible file of your inventory.
This usually happens if browser data was cleared. To prevent data loss:
Try these steps:
Check the sync indicator dot next to "FilamentTracker" in the sidebar:
If connection drops, inventory changes are queued locally and replayed automatically once cloud sync reconnects.
