First Time Setup

Before entering the app for the first time, you need to agree and accept the User Privacy Protection Agreement. After choosing to agree, the app will prompt to turn on notifications. We recommend that you turn on notifications in order to receive information such as the printer’s print status. After this, the app will automatically enter the main screen

Sign In/Sign Up

After entering the main interface, click the Me button on the right side of the navigation bar at the bottom to enter the “Me” page, and click Login/Register at the top of the screen to complete account registration or login. Bambu Handy can be logged in using email address, Google account or Facebook account.

Add Printer

After successfully logging in to your account, click the Devices button in the navigation bar to enter the Devices page, and then click the + button in the upper right corner to add a printer. Some cell phone systems will show a prompt for permission to find nearby devices, click on it to allow the Bambu Handy app to find printers. Printers need to be connected to the network to use Bambu Handy to bind to the account, X1 and A1 series can be connected to the network directly through the printer interface, P1 series need to use Bluetooth to connect to the printer before connecting to the network, for more information, please refer to P1 series printer network binding troubleshooting guide. When the printer is in the same LAN as your phone, the device list in the Bambu Handy app will automatically show the found device. X1 and A1 series also support binding the device by scanning the QR code by clicking the scan button on the upper right corner.

Note: The Bambu Handy does not currently support printer LAN mode and must use the Internet to connect to the printer. LAN is only used for printer discovery, data transfer needs to be accomplished over the Internet. For more information on LAN mode, please visit How to enable LAN Mode on printers.

After completing the binding, if this is the first time you are using the 3D printer, you might need to follow the app prompts to remove the limiting parts that were installed on the printer in transit. If this is not your first time using the printer, you can skip this step by clicking Confirm.

[Device] Screen Functions

After completing the printer binding, the application will automatically return to the device screen. The device screen contains the monitoring image returned by the printer, the item currently being printed (or the last previously printed item), and the printer controls.

Printer Monitoring Image

You can view the current returned image at any time by clicking the play button in the monitor image returned by the printer. Click the Camera button at the bottom right corner of the screen to take a picture, and the captured picture will be saved to the cell phone album. You can also click the Full Screen button at the bottom right corner to enter full screen mode to view the returned image. In full-screen mode, users can adjust the screen size by two-finger zoom, so that it is easy to observe the printing details.

Print Project

The Print Items module displays only the last item printed by the binded device if no item is currently printing. If the device is printing, the module displays the currently printing item and the print control options. If printing was initiated through the printer, the module only displays the Pause and Stop options, but if the print item was sent to the printer from Bambu Studio, the module displays the Skip Part option in addition to Pause and Stop. This option will be covered in the advanced features part of this article.

Printer Control

Printer Control contains control options for both the printer and AMS sections. On the main screen, you can directly control the nozzle temperature, heat bed temperature and speed, or click on the color block corresponding to each filament to view material information. Clicking on Printer or AMS on the left side of the module takes you to the detail page, where you can move the printer axes in addition to what you can do on the main screen, control some parts (such as the light and cooling fan), and control the AMS to perform load/unload actions.

Advanced Features

This section focuses on the two more advanced modules of the application.

There are two situations where you can select specific printing part. One of them is when the print is sent to the printer by bambu studio, you can select which part to print in the devices screen. The other is if the print is initiated from print history or pulled directly from MakerWorld. In both situations, if there are multiple parts in one plate, you can select which part you want to print using Print Parts/Skip Parts function, thus saving both time and materials. Note that if you choose to skip a part during the printing process, the operation can not be undone, and you will need to start printing again if you want to print the part.
