A proprietary tool that was supposed to have been removed due to pressure from 3D printer manufacturers has been re-released by a non-profit organization.
In May 2026, following legal action threats from 3D printer manufacturer

Bambu Lab is a 3D printer manufacturer based in China and the United States, specializing in personal desktop 3D printers. Developer Pavel Yarčak has released a custom tool called ' OrcaSlicer-bambulab ' on GitHub for directly controlling Bambu Lab's 3D printers and their Orca Slicer software.
However, Bambu Lab claimed that this tool was 'impersonating Bambu Lab,' 'circumventing authentication controls,' 'violating the terms of service,' and 'reverse engineering,' and threatened legal action against Jarček.
Yarčak denies the claims made by Bambu Lab and has requested specific details and legal basis from Bambu Lab, but has not received a satisfactory response. He has also removed the BambuNetwork path that he used to connect and manage Bambu Lab's product portfolio.
Ultimately, Yarčak was forced to remove the code and related materials from the 'OrcaSlicer-bambulab' GitHub repository. In a statement left in the repository, Yarčak argued that the tool was created in accordance with the AGPL license of Bambu Lab's code and that Bambu Lab's claims were unfounded. He condemned the accusation that it was absurd to brand him as 'a person dangerous to Bambu Lab's infrastructure' when he had developed the tool for Bambu Lab and its users.

In response to the series of events, YouTuber Luis Rothman , who works to protect the 'right to repair,' has called on Yarchak to restore the repository and has also offered financial support.

Amidst this situation, the non-profit organization FULU Foundation created a repository called 'OrcaSlicer-bambulab' on their GitHub account. This repository already contains the code that Yarchak had deleted, and they have also restored full support for BambuNetwork.
The FULU Foundation is a non-profit organization founded by Rothman and others to resist corporate infringement of intellectual property rights. The FULU Foundation opposes companies controlling products purchased by users via the internet, digitally locking them to render them unusable, and violating user privacy.
Rothman explained the sequence of events in a video he posted on his YouTube channel.

After Rothman expressed his support for Yarčak, the two reportedly discussed the 'OrcaSlicer-bambulab' case. Yarčak himself was not interested in a long legal battle and simply wanted to point out that Bambu Lab was violating the AGPL license.
Therefore, Rothman decided to redistribute the 'OrcaSlicer-bambulab' code through his non-profit organization.
In his work advocating for the right to repair, Rothman has faced legal threats from various large corporations in the past. However, he argues that in many cases their legitimacy has been recognized, and that no lawyer would want to represent Bambu Lab.
'I am certain your lawsuit is rubbish. Go ahead and delete my GitHub repository. Send me a restraining order. I look forward to receiving your notification,' Rothman said.
