3D printers automatically print at night, scaring consumers. Manufacturers say it’s caused by cloud failure

News from this website on August 23. Recently, many users who own 3D printers from Bambu Lab (Tuozhu Technology) found that their printers automatically started printing tasks at night, causing some printed works to be damaged, and even some printers be damaged. Bambu has identified the cause of the issue and is implementing a software fix to prevent users from worrying about whether their 3D printer is possessed by a ghost or has become self-aware.

Bambu Corporation confirmed that a recent cloud outage disrupted the remote functionality of its 3D printer, causing the 3D printer to become unavailable during the night Start a print job without the owner's consent. The company is taking a number of new security measures to ensure something like this never happens again.

Bambu Company’s investigation revealed that on the night of August 15, an MQTT SDK client timed out, causing the cloud infrastructure responsible for remote 3D printing tasks to fail. There is an outage at the facility. During both disconnections, the cloud-connected printer queued and initiated print jobs while the owner was sleeping. Some printers have destroyed work still on the platform by repeating print jobs without confirming completion of the first job, and some even experienced damage to the devices themselves.

Bambu Corporation said it takes full responsibility for the incident and will update the firmware to add security steps during the printing process and give users more control. The X1 series of printers, thanks to their LIDAR (Lidar Radar), can add a function to check whether there are objects on the platform before starting a print job. P1 series printers do not have LIDAR and will require users to check the platform and confirm before starting to print. In addition, the system will strictly check task timestamps to reduce the possibility of repeated errors.

Perhaps the most serious issue with this incident is that the heat generated by 3D printers can pose a fire hazard, so all Bambu printers after the update will turn off the heater and alert the user when abnormal temperatures are detected. In addition, Bambu plans to improve the LAN mode so users can remotely control their printers without being connected to the Internet or the company cloud, and local file management and download functions are also coming soon.

This site noticed that Bambu has not yet provided a timetable for launching patches, but it has provided repair and replacement parts services for those damaged printers. The company will also reimburse wasted thermoplastic filaments and guarantee two randomly selected reels of PLA filaments for free.
