#HobbyStreak day 1338:
Ya boi Erik hath joined the realm of #3Dprinter parents. Just what I needed in my household: yet another entity that's moody, temperamental, overly sensitive and has a metric tonne of unwritten rules.
First order of business: fkn 0.2 nozzle should be easy but was Pluck&Pray😑
Second fkn order of biznitch: why does #OrcaSlicer add what seems like a non-functioning line of code to the filename output box? Can we please fkn not?😑 gcode wouldn't export
Si queréis calibrar vuestra impresora 3D para que los puentes y los voladizos os salgan medio decentes, acabo de publicar un proyecto en OrcaSlicer en Printables que os va a ayudar a hacerlo. Ya que me he pegado la matada, al menos que a alguien le ahorre tiempo XD

THE CLOSED-SOURCE SHACKLE: Analyzing Bambu Lab’s Approach to AGPL Compliance
2,695 words, 14 minutes read time.
Bambu Lab took the open-source guts of 3D printing, forked the hell out of it under AGPLv3, built a slick empire on top, and then slapped a closed-source shackle around the whole damn thing. This isn’t some gray-area technicality. It’s a straight-up betrayal of the license that gave them their unfair head start. They ship printers that print like a dream while quietly locking down the machine’s soul behind proprietary walls. The RepRap boys built this industry on dirt, sweat, and full ownership. Bambu turned it into a corporate cage.
The Core Violation
The smoking gun sits right in Bambu Studio — their slicer, forked straight from PrusaSlicer under the AGPLv3. That license is brutal for a reason: modify it, distribute it, especially over a network, and you release the full source. No hiding pieces. No “optional” bullshit.
Bambu loads a closed-source bambu_networking plugin that handles cloud auth, remote control, and core features. It auto-downloads, dynamically links, and becomes part of the program. The Software Freedom Conservancy already called it what it is: a clear AGPL violation. You can’t carve out the heart of the software, close it off, and still claim you’re playing by the rules. This is license laundering, plain and simple.
They reaped the open-source commons like bandits, then built their castle walls with the stolen stones.
The 2025-2026 Escalation
When a developer named Paweł Jarczak did what real men in this space do — forked the code and restored direct functionality — Bambu didn’t compete. They lawyered up. Cease-and-desist letters, accusations of impersonation, reverse engineering, the whole corporate playbook. The fork came down fast.
That move lit the fuse. It dragged the whole mess into the open. The SFC launched a formal compliance review. Josef Prusa himself called out the unauditable black box. Suddenly the world saw what Bambu was really protecting: not innovation, but control. Their new Bambu Connect middleware pushed even more traffic through their servers, tightening the leash.
This wasn’t defense. It was panic dressed up as professionalism.
Bambu’s Defense and Why It Stinks
Bambu’s line is the usual slick corporate speak: the networking plugin is “optional,” their cloud is private infrastructure, and they love open source — just not when it steps on their turf.
The plugin isn’t optional when the slicer leans on it for basic modern functions.
AGPL doesn’t care about your marketing slides or how you label components. If it forms one integrated product — and it does — the whole thing must ship with source.
They want the credibility of the open-source roots without the obligations. Classic embrace, extend, extinguish.
No amount of smooth PR changes the fact they’re treating the community that built this industry like unpaid interns who should be grateful for the privilege of buying their locked-down gear.
The Brutal Reality
This is bigger than one company. It’s the old fight between men who want to own their machines down to the last bolt and corporations that see full ownership as a bug, not a feature.
Bambu makes hardware that performs, no denying that. But performance bought with closed-source shackles comes at a price: you paid for the printer, yet they still own part of its soul.
The RepRap era was ugly, dirty, and free. Bambu’s era is clean, fast, and leased. They didn’t invent the tech — they commodified it and put a fence around it. The AGPL drama proves they know exactly what they’re doing.
In the end, the closed-source shackle isn’t an accident. It’s the business model. And the industry that started with hackers in garages is learning the hard way what happens when the suits move in and start changing the locks.
Call to Action
So what are you going to do about it, brother?
Stand with the Software Freedom Conservancy — the crew already hauling Bambu’s AGPL violations into the daylight — alongside real right-to-repair warriors like Louis Rossmann, Kyle Wiens at iFixit, and the lawmakers grinding through repair legislation in Europe and the States. These men aren’t asking permission; they’re exposing how companies twist DRM laws — originally built to stop movie piracy — into weapons for permanent digital lock-in.
Bambu’s closed-source networking shackle and cloud middleware are textbook abuse: they take hardware you paid hard cash for, wrap it in proprietary chains, and then hide behind “security” and “user agreements” while daring you to touch what’s yours. Rossmann has spent years ripping the mask off this exact corporate game. It’s the same play — control the software, control the machine, control the man who bought it.
Ditch the cage. Support Prusa, run a Voron, back true open forks, and fund the SFC’s compliance fight. Demand full source code. Call out every violation publicly. Build loud, repair louder, and make it painful for any company that tries to lease the soul of your gear.
The RepRap spirit was born in garages by men who refused to kneel to suits. That fire doesn’t have to die just because the hardware got slick. Own your machines — every bolt, every line of code, every function — or keep paying rent on your own property.
The choice is still yours. For now. Make it count.

Oh no, #flashforge is the next #3dprinter to #enshitify!!!! #3dprinting
The new firmware injects #ai ads into your slicer software 🤦
Auch wenn die Schlagzeile wieder mal eine journalistische "Meisterleistung" ist, die Thematik ist für FDM 3D-Druckende sehr interessant!
Aber der Physik "ein Schnippchen schlagen". Holy Moly 🤦♂️

@[email protected] on interesting reasons why #bambulab breaks #AGPL and threatens the community. Basically: Keeping their code secret for (industrial) espionage because chinese law requires it. So maybe don’t contaminate your network with a Bambulab printer? (On twitter unfortunately, but here’s a link to #xcancel) https://xcancel.com/josefprusa/status/2054602354851254330 #3DPrinting
Der Druck auf Bambu Lab steigt.
(auch gleich ein Wortspiel mit dabei 😅)
Nun steigt die Software Freedom Conservancy (“SFC”) mit ein in die Thematik und geht auf Konfrontation mit Bambu Lab. 👍
Dazu kommt der Streisand-Effekt.

Software Freedom Conservancy (“SFC”) announces a new initiative regarding the software right to repair for users and consumers of 3D printers manufactured by Bambu Lab. After recent news of violations of the Affero General Public License, version 3 (“AGPLv3”), SFC staff began a comprehensive AGPLv3 compliance investigation of both the userspace software and firmware on Bambu's devices. While the investigation is ongoing, two specific AGPLv3 violations have been confirmed.
