# Bambu Bar
**Your Bambu Lab printer, one click away in the menu bar.**
Bambu Bar is a native macOS app that shows your 3D printer's progress, temperatures and filament without opening Bambu Studio or Bambu Handy. Glance at the menu bar for percent and time left, click for everything else, or keep a widget on your desktop.
Built with Swift and SwiftUI. No account, no cloud service, no analytics.

> Independent, community-developed software. Not affiliated with or endorsed by Bambu Lab. A P2S is the development printer; other Bambu Lab printers that speak the same LAN protocol (X1, P1, A1, H2) should work.
## Why this app?
The printer is in another room, and the slicer is a big app to keep open just to see how long is left. Bambu Bar keeps the answer in the menu bar: **64% · 1h 02m**. Click it and a panel shows the job, the stage, temperatures, the spool in use and how much filament is left, with pause, stop, light and speed controls right there.
It talks to the printer directly over your network, the same way Bambu Studio does in LAN mode, so it works with the printer still bound to your Bambu account and nothing goes through a cloud.
## Features
| | What you get |
| --- | --- |
| **Menu bar** | A printer glyph that fills as the print grows, with progress and time left beside it (or just one, or only the icon), and a pause or alert mark when the printer needs you. |
| **Panel** | The job, its stage ("Heating hotend", "Paused: filament ran out"), percentage, layers, time left and finish time; nozzle, bed and chamber temperatures; AMS spools with what's left and the humidity; printer errors in plain English. |
| **Grams left** | Bambu Lab spools tell the AMS their net weight, so Bambu Bar shows filament left in grams (≈ 810 g), not just a percentage, and how much you have on hand in total. |
| **Named filament** | Bambu Lab spools show their colour by name (Grass Green, Charcoal). Other spools show the maker and product of the preset you set the slot to on the printer or in Bambu Studio, such as SUNLU PLA Matte. |
| **Controls** | Pause, resume, stop (with a confirmation), print speed (Silent, Standard, Sport, Ludicrous) and a chamber light switch. |
| **3D printer models** | Each printer family is modelled in Blender: the P2S/P1S/X1 enclosure, the wider dual-nozzle H2, the open P1P frame, the A1's arch with its AMS Lite, the A1 mini. In the app it's a live 3D model you can turn with the mouse: the print grows layer by layer in the filament's colour, the bed drops (or the A1's gantry rises) as it goes, the toolhead moves while printing, the AMS spools take their real colours and the chamber light follows the printer's. Widgets use studio renders of the same models. |
| **Knows your model** | What each model has comes from the printer profiles Bambu Lab publishes with Bambu Studio, so you only see what your printer can report: no chamber temperature on an A1 or P1S, no door or chamber li
