Spoolstamp — Free, open-source filament labels for Bambu Studio

Other topics
1

Hi everyone! I built Spoolstamp because I wanted to make filament labels without manually editing text for every material and color.

Try it: https://spoolstamp.bourhan.org/
Source code: GitHub - byassin/spoolstamp: Filament label studio with live 3D preview, Bambu Lab catalog, local AMS inventory, and color-aware 3MF export. · GitHub

Choose a Bambu filament type and color, pick a label design and printer profile, and preview it in 3D. Spoolstamp fills in the lettering, uses the filament color for the body, and picks contrasting black or white text. Download the color-aware 3MF, open it in Bambu Studio, and slice.

What it does

  • Searchable Bambu filament catalog with material types, color names, and codes
  • Two label styles: a hinged dry-box label and a flat-front clip-on label
  • Live 3D preview with rotation, zoom, and printer-sized build plates
  • Separate body and text filament profiles in the 3MF export
  • Local My AMS integration for loaded-spool suggestions, compatible text-spool suggestions, and batch label exports

The website needs no installation for label generation and downloads. Running Spoolstamp locally adds My AMS and one-click opening in Bambu Studio. You still slice and confirm the physical AMS slot assignments in Studio.

I’ve been testing printed labels on my own setup; the photo below shows the hinged labels in use.

It’s free to use, and the application code is MIT-licensed. Questions, issues, and feature requests are welcome in this thread or on GitHub Issues. I’d love to hear what layouts or improvements would make it more useful for you. Code contributions are welcome too.

Design credits: the hinged and clip-on templates are adapted from work by Genetic Designs and Stag 3D, respectively.

What do you think of PLA Tough+?

Any chance to pull the filament information from Spoolman?
Just finished setup with Spoolman and BambuLab AMS Spoolman Filamentstatus.

…and, what’s the outcome for setting up Spoolman and the add-on?

For me

  • it works better than the Bambu Studio Filament Manager. Usage is reduced from the prints reports the add on gets from the printer over MQTT.
  • I use Orca Slicer exclusively, so the Bambu Studio Filament manager is not an option for me anyway
  • its all local (I am in LAN only mode and Developer mode anyway)

But, and that’s what many will not like, I think it works only in LAN only mode and Developer mode. But that’s my setup anyway.

That’s what suits me as well. Thx for sharing. I might get back to you via PM should I have some questions about Spoolman. I’m running only X1Cs and stopped updating the firmware since Bambu’s "security patch " BS (on January 16th 2025)

@drakko

Keep in mind, I am just a user, not the developer! :fearful:
For Bambu Studio Filament Manager, there is a separate thread here from the developer ==> Track Bambu Lab Spools in Spoolman - #34 by beegee-rakwireless

Installation was quite simple using Docker on my RPI5 that is here anyways (doing a lot of other things)

Thanks for sharing! If you use Spoolstamp in local mode it shoud connect directly to your AMS (you can have it in LAN only mode or not) and read your spool data. The idea is to read from what you have loaded in your AMS so it can find the right label for it and not from you entire inventory. I will have to take a close look at Spoolman to see if it makes sense to read through it vs the AMS directly.

Seems I need to give it a try.
I like Spoolman because I can have my external spools setup there as well.

With “connect directly to your AMS” you mean it listens into the MQTT stream from the printer, like Bambu Studio Filament Manager does?

10

That is correct. This is what it does:

  1. Connects to the printer using encrypted MQTT on port 8883, authenticated with your LAN access code.
  2. Subscribes to device/<printer-serial>/report, where the printer reports AMS slots, filament colors/types, and remaining estimates.
  3. Requests printer information and a full status snapshot when connecting, then refreshes the snapshot every 30 seconds while also listening for updates.

I like this : I’ll have a try
thanks for sharing

The spool tag labels on the AMS should be screens.

All our local supermarkets already have digital price tags on the shelves.

those supermakets make money from such labels, I’d rather not have increased costs and being tied in another way with the printer brand , as I doubt such feature would be open source
