Open-source non-profit claims Bambu Lab violated license — move follows cease-and-desist demand on OrcaSlicer fork that restored cloud printing features without using Bambu Connect

The SFC says that including proprietary code alongside software under AGPLv3 breaks the open-source license, and that Bambu Lab has been doing this for years.

Why this matters
Why now

This cease-and-desist action follows a prior fork that restored cloud printing features, forcing the issue of open-source license compliance in a rapidly growing hardware segment.

Why it’s important

It highlights the tension between open-source principles and proprietary business models in hardware, which can impact innovation and user control.

What changes

The dispute could force Bambu Lab to alter its software distribution practices, potentially affecting its product ecosystem and competitive standing.

Winners
  • · Open-source foundations
  • · Users advocating for license compliance
  • · Competitors with fully open hardware/software stacks
Losers
  • · Bambu Lab
  • · Companies mixing proprietary and AGPLv3 code
  • · Users relying on specific cloud features
Second-order effects
Direct

Bambu Lab faces legal and reputational pressure to comply with open-source licenses, potentially leading to software modifications.

Second

This could set a precedent for license enforcement against other hardware manufacturers integrating AGPLv3-licensed software with proprietary components.

Third

Increased scrutiny on open-source compliance might lead to a greater adoption of fully open-source hardware designs or clearer licensing strategies across the industry.
