Bambu Lab apps on a Mac: which one does what

The four apps at a glance

Bambu Studio: slicing and sending

Bambu Studio is where prints begin. You open a model, pick the filament and settings, slice it and send it to the printer. Its Device page shows progress and the camera, but only while Studio is open and in front of you.

That's the gap most Mac users notice: once the job is sent, you don't want a full slicer window open for the next six hours just to see how far along it is. More in Bambu Studio on your Mac.

Bambu Handy: your phone, and maybe your Mac

Bambu Handy is made for the iPhone and iPad. Its App Store listing says it's designed for iPad and not verified for macOS, and lists Apple silicon Macs on macOS 13 or later as compatible. On an Intel Mac it doesn't run at all, and while the printer is in LAN Only mode it isn't available.

Handy shines away from home, through Bambu Lab's cloud. At your desk, an iPad app in a window is a stretch. More in Bambu Handy on a Mac.

Bambu Connect: the go-between for other slicers

Bambu Connect is Bambu Lab's app for sending print jobs from third-party software, such as OrcaSlicer, to a printer on current firmware. If you slice in Bambu Studio, you don't need it: Studio talks to the printer itself.

Bambu Connect is built for sending jobs, not for keeping an eye on them. More in Bambu Connect, explained. And you don't need it for Bambu Bar: Bambu Bar works without Bambu Connect installed.

Bambu Bar: your printer in the menu bar

Bambu Bar is the one you look at all day. Your print sits in the Mac menu bar (64% · 1h 02m at a glance), and a click opens the job, temperatures, the AMS spools with grams left and the live camera. Add desktop widgets, get a notification when a print finishes, fails or runs out of filament, and press ⌘K for a floating camera window that stays on top while you work.

• Straight from the printer: it connects on your local network, with no Bambu Lab sign-in, in cloud mode and LAN Only mode alike.
• Every Mac: macOS 26 or later, on Apple silicon and Intel.
• Every printer: all 15 Bambu Lab models, as many as you have, at once. Running a small farm? See Bambu Farm Manager on a Mac?
• Your PC too: Bambu Bar for Windows puts the same printers in the tray by the clock, with desktop widgets, the camera and Windows notifications, on Windows 10 and 11.
• Free to use, with an optional one-time $9.99 supporter license for automatic updates and the Hero Supporter badge. One key activates one Mac and one PC.

It doesn't slice, and it doesn't reach your printer from outside your home: that's what Bambu Studio and Bambu Handy are for.

Which should you install?

Pick by what you want to do:

• Slice and send prints: Bambu Studio, or OrcaSlicer if you prefer it (OrcaSlicer vs Bambu Studio).
• Check prints while you're out: Bambu Handy on your phone.
• Send from OrcaSlicer on current firmware: Bambu Connect, or Developer Mode.
• Keep an eye on prints while you work: Bambu Bar, in the menu bar and on your desktop (on a PC, in the Windows tray).

On an Intel Mac

Bambu Handy doesn't run there. Bambu Studio and Bambu Bar both do, natively.

In LAN Only mode

Bambu Handy stops working, because it goes through Bambu Lab's cloud. Bambu Studio keeps working on your network, and so does Bambu Bar, which never needed the cloud. See Bambu Lab LAN mode.

Can I use more than one?

Yes, and most people do. They each do a different job, so they get along:

• Bambu Studio + Bambu Bar: slice and send in Studio, then close it. Bambu Bar reads the printers and access codes Studio already saved, so setup takes a click.
• Studio + Bambu Bar at home + Handy away: keep the printer in cloud mode, and you have your desk and your phone covered.
