TL;DR
Bambu Lab has publicly threatened legal action against an open source developer modifying their slicer software. This move has sparked criticism over the company’s approach to open source and community collaboration. Details remain uncertain about the full scope of the dispute.
Bambu Lab has publicly threatened legal action against an open source developer who created a fork of their slicer software, raising concerns about the company’s approach to open source collaboration and community trust.
The dispute centers on a fork of OrcaSlicer, an open source project derived from Bambu Studio and Prusa Slicer, which was modified to allow users to bypass Bambu Lab’s cloud services. Bambu Lab accused the developer of impersonation and security threats, claiming the fork injected falsified identity data into network communications to mimic their official client.
In response, the developer denied wrongdoing, stating that the modifications used upstream code licensed under AGPLv3 and that Bambu Lab’s accusations are unfounded. The company’s public blog post characterized the developer’s actions as an impersonation attack, though the developer argues that the fork used identical code without malicious intent. Bambu Lab’s actions include a cease-and-desist-like statement, which critics say is an overreach that threatens open source principles.
Why It Matters
This development is significant because it highlights tensions between proprietary interests and open source communities. Bambu Lab’s aggressive stance against a small developer raises concerns about potential suppression of community-driven innovation and transparency. The incident underscores ongoing debates about how companies should engage with open source projects, especially when modifications challenge their business models or security assumptions.

Background
Bambu Lab, a prominent manufacturer of 3D printers, has increasingly integrated cloud services into its products, controlling firmware updates and print data. Critics argue that this approach compromises user ownership and privacy, prompting some users and developers to create forks that remove or bypass these features. Last year, Bambu Lab faced criticism for its ecosystem restrictions, and this recent dispute adds to ongoing community concerns about corporate overreach and open source ethics.
“Bambu Lab is abusing the open source social contract, and using their legal might, to suppress a tiny number of their users for reasons unknown.”
— OrcaSlicer-bambulab developer
“The fork injected falsified identity metadata into network communication, pretending to be the official Bambu Studio client.”
— Bambu Lab blog post
“I would pledge $10,000 to help the open source developer fight Bambu’s legal threats.”
