Bambu Lab Under Fire: AGPLv3 Violated and Developer on the Run

Published on May 23, 2026 | Translated from Spanish

The battle for open source in 3D printing intensifies. YouTubers like Louis Rossmann and Gamers Nexus have donated $20,000 for a developer's legal defense, while the Software Freedom Conservancy confirms two violations of the AGPLv3 license by Bambu Lab. The conflict exposes the tension between manufacturers seeking to close their cloud platforms and a community demanding transparency.

Duplicated Code and Broken Licenses: The Jarczak Case ⚖️

Developer Jarczak defended his fork by arguing that he used Bambu Lab's source code without modifications, which is legal under AGPLv3 if the terms are respected. However, the Software Freedom Conservancy detected two infringements prior to the Jarczak incident, including the failure to distribute source code for cloud components. The organization plans a legal offensive against the Chinese company, pointing to a pattern of progressive enclosure that contradicts the spirit of free software.

The Cloud That Darkens: The DRM Nobody Asked For 🔒

It seems Bambu Lab confuses open source with a safe. If you want to close your ecosystem, do it like Apple and don't pretend to be a friend of free software. Meanwhile, the developer will have to move their code to a server on Mars to avoid being sued. The community is already wondering if the next update will require a fingerprint to change the filament.
