Polar3D Bridge
One app, any OS, two major printer brands. The Bridge connects your Bambu Lab and Prusa printers to Polar Cloud over MQTT and other local options — from a Mac, Windows, or Linux machine on your network.
Online in Three Steps.
The Bridge speaks your printers' local protocols, so there's nothing to flash and nothing to solder.
Install the Bridge
Download the Bridge for Mac, Windows, or Linux and run it on any computer that shares a network with your printers.
Link Your Printers
The Bridge discovers your Bambu Lab and Prusa printers over MQTT and other local connection options and links them to your Polar Cloud account.
Manage From the Cloud
Your printers show up in the Polar Cloud dashboard — queue, slice, monitor, and share them with your class or team from any browser.


Made for Mixed Fleets.
Real labs rarely run one brand of printer on one operating system. The Bridge meets your hardware where it is.
Bambu Lab + Prusa Together
Run both brands side by side in a single Polar Cloud dashboard, with one queue and one set of permissions across your whole fleet.
Any Operating System
Mac lab? Linux server closet? Windows front desk? The Bridge runs on all three, so you don't need to buy hardware just to get connected.
Local-First Connectivity
The Bridge talks to printers over MQTT and other local connection options on your own network, then syncs securely with the cloud.
