Bambu Lab printers are great machines all around, but they do have a few drawbacks. An important one to many Bambu users is the constant sending and receiving of data to and from Bambu’s servers. This can worry privacy and security-centric users who want to keep their printer’s data away from possible prying eyes.
Fortunately, Bambu designed a mode to counter exactly this, LAN Only mode. It’s a highly useful tool for keeping your prints and printer secure on the network.
LAN Only mode, as the name suggests, forces the printer to operate solely on the local network. This means that the printer is allowed to communicate with, for example, a computer on a home or workplace network where the printer is located, but it’s not allowed to communicate with any external device.
This can present some pros and cons: The printer will remain “private” and will no longer be able to contact any servers, including Bambu’s, but this also means losing access to quite a few features that depend on this connection.
In this article, we’ll go a bit deeper into the benefits and drawbacks of LAN Only mode, and we’ll then explain how to set it up on your own printer.
LAN Only mode is useful in that it provides a good balance between a completely offline and a completely connected printer.
Prints can still be started and monitored via Bambu Studio running on a device on the local network, and the printer can still automatically detect print failures (on capable models such as the X1 Carbon).
On the other hand, not being able to reach Bambu’s servers results in the downside of not being able to start or monitor prints outside of the local network, the inability to use Bambu Handy, and the lack of a Print History function.
Although this does result in losing some of the printer’s functionality, it may still be worth it for security-conscious users who don’t want their printers being monitored or even controlled by Bambu. Additionally, cloud-based systems can have issues and might go offline from time to time or start unprompted, so keeping everything local is an effective way to ensure that things continue working even when the cloud falters.
Now that we’ve gone over LAN Only mode and its benefits and drawbacks, we’ll explain how to set it up on your machine.
This is a two-part process. The first occurs on the printer, and the second is done in Bambu Studio.
Where you need to navigate for the first part differs slightly based on your printer model, but the common objective is to find and take note of the “Access Code” for the second part.
Now, it’s time to bind the printer to Bambu Studio.
That’s all! Your printer is now set up, cloud-free.
