3D Bambu Lab Under Formal Investigation Over Software License Violation.

Bambu Lab, a leading consumer 3D printer manufacturer, is now under formal investigation following allegations of violations of the AGPLv3 open-source software license, according to reports from the Software Freedom Conservancy. The dispute centers on claims that Bambu Lab has used AGPLv3-licensed code within its 3D printing software ecosystem while allegedly failing to fully release corresponding source code for modified or tightly integrated components, particularly those related to cloud connectivity and printer communication. The AGPLv3 license requires that any modified software based on covered code—especially software accessed over a network—must be made available to users in full source form under the same license. Critics argue that separating proprietary networking or cloud modules from the open-source core may be an attempt to circumvent these obligations. The investigation highlights growing tensions in the 3D printing industry over open-source compliance as companies increasingly blend open-source foundations with proprietary cloud services and closed-source features.
