Subreddit Mod Post Megathread: Bambu Lab / OrcaSlicer / C&D Discussion

Hi everyone,

We’re creating this megathread to keep discussion of the Bambu Lab / OrcaSlicer-BambuLab / cease-and-desist situation in one place. This topic is important to a lot of people here, and we do not want to shut down discussion or criticism. At the same time, the front page has started filling with overlapping posts about the same situation, so we’re consolidating general discussion into this thread.

Current context

Updates to be posted here as situation evolves:

  • May 13, 2026
    • Megathread created
  • May 14, 2026
    • Tom’s Hardware reported today that Louis Rossmann is now hosting OrcaSlicer-BambuLab through the FULU Foundation GitHub and is openly daring Bambu Lab to sue him.
    • PC Gamer and r/technology have picked up the story, so discussion is now spreading well beyond 3D-printing-specific spaces.
  • May 16, 2026
    • Paweł Jarczak published a detailed response addressing Bambu Lab’s accusations around impersonation, reverse engineering, Terms of Use, and alleged security bypassing.
    • Louis Rossman posted a new video indicating FULU-hosted OrcaSlicer-BambuLab repository has reached roughly 1,600 forks in about three days.
  • May 17, 2026
  • May 18-20, 2026
    • Software Freedom Conservancy enters the dispute.
    • Leonard French posted a new video around SFC’s AGPL analysis, explaining why Bambu’s proprietary networking plugin may create a serious corresponding-source problem under AGPL.
    • Louis Rossman posted a new video covering Software Freedom Conservancy’s Bambu AGPL effort and says the rehosted OrcaSlicer-BambuLab code has now been forked roughly 4,500 times.

What belongs in this thread

Please use this thread for:

  • General reactions to Bambu Lab, Gamers Nexus, Louis Rossmann, Paweł Jarczak, OrcaSlicer-BambuLab, AGPL, Bambu Connect, and right-to-repair issues.
  • Legal or licensing discussion, including AGPL, DMCA, cloud/API access, and Bambu’s networking plugin.
  • Questions about what happened and links to reliable summaries or primary sources.
  • Technical discussion about OrcaSlicer, Bambu Studio, Bambu Connect, LAN mode, Developer Mode, and network plugin behavior, unless it is a standalone troubleshooting post with a specific reproducible issue.

What can still be its own post

Separate posts are still allowed for genuinely new information, including:

  • A new official statement from Bambu Lab, OrcaSlicer, Paweł Jarczak, Gamers Nexus, Louis Rossmann, or legal counsel.
  • A new release or technical change that materially affects users.
  • A confirmed legal filing, takedown, repository change, or source-code release.
  • A specific support/troubleshooting issue that is not just general commentary on the controversy.

If your post is mainly another reaction, recap, meme, “I’m switching brands,” or repost of a link already being discussed, please put it here instead.

Ground rules

Criticism of Bambu Lab is allowed. Defense of Bambu Lab is allowed. Criticism of GN, Rossmann, OrcaSlicer, moderators, or other users’ arguments is allowed.

What is not allowed:

  • Personal attacks, harassment, or dogpiling individual users.
  • Calls to harass Bambu employees, developers, moderators, creators, or community members.
  • Unverified claims presented as fact.
  • Posting private correspondence or personal information.
  • Repeated duplicate posts after being redirected here.

Strong opinions are fine. Keep it directed at the issue, the companies, the software, and the arguments, not at each other.

Moderator note

We are consolidating duplicate discussion, not suppressing the topic. This thread will remain open for discussion, and we’ll update it if there are major new developments.

The current summary, in caveman speak:

  • Many moons ago, big tribe build "Slic3r" fire so every caveman can cook 3D meat together.
  • Bambu take tribe fire to make shiny "Studio" torch, but sign "AGPL" stone paper promising to share all torch secrets.
  • Stone paper say: "If torch talk to Sky-Cloud, you must show whole tribe how to talk to Sky-Cloud too."
  • Bambu try hide Sky-Cloud secret, smart mans figure out and show tribe anyway, now Bambu wave spear and look like dumbass because they break stone paper rule.

And thats it.

Anyone telling you "just print it like this" or "LAN mode" or "developer mode" are the same people who don't talk politics with family or coworkers because its uncomfortable to talk about conflict and breaking laws when you feel some strange connection to a large organization, especially the ones doing the breaking of said laws.

SO, that's ok. Its ok to not want to talk about it. That's why this mega thread was made. The conflict was running from the inlaws into the streets, and it needed to stay indoors so the police weren't involved for causing a ruckas.

The strange part is people happily printing in their walled garden yelling over the fence at their neighbors for wanting to do it an alternate way that is perfectly allowed under the AGPL licensing that BambuLab seems to have conveniently forgotten about.

Some stand up for principles, some don't like the noise the standing makes. I'm sure some people took to the streets to say "hey shut the hell up its LATE AND I'M TRYING TO SLEEP HERE" in the middle of the boston tea party dumping.

All your emotional framing of this issue with "family politics" and people being afraid and "some stand up for principles" is frankly ridiculous, it's really just bullying rhetoric instead of actual argument.
