Locked Out Again: Firmware Restrictions Spread From Toner to 3D Bambu Lab Printers.

Open-source firebrand Louis Rossmann has declared war on 3D Bambu Lab after the company attempted to shut down a banned firmware fork that restored user control over its increasingly locked-down 3D printers. Rossmann mocked the billion-dollar company by publicly hosting the forbidden software himself and openly daring 3D Bambu Lab’s lawyers to sue him, igniting outrage across the maker community. Critics accuse 3D Bambu Lab of abandoning the open-source spirit that helped fuel its explosive rise, comparing the company’s cloud restrictions to the same anti-consumer tactics used by inkjet printer giants notorious for blocking third-party cartridges and controlling customer hardware. The controversy has now spiraled into a full-scale rebellion, with creators calling for boycotts, developers mirroring the banned code across the internet, and rival manufacturer Snapmaker stepping into the fight by donating equipment to the targeted developer — a move many see as both solidarity and a direct shot at Bambu Lab’s reputation.
