Features
Everything from the slicer
to the finished part.
One place for every print: start it, watch it, keep it. On the laptop, on the phone and on a screen right at the printer.
See every layer first.
Scrub through the G-code in 3D before a gram of filament moves, then follow the nozzle while it prints.
A timelapse of every print.
A frame at every layer, turned into a video when the print is done.
Know when it's done.
A Telegram message with a photo, a webhook for your smart home, a note in the browser tab.
One Pi, several printers.
Printers on USB and Bambu Lab printers on the network, all on one Pi. Switch between them in one click.
Power on, power off.
Switch the printer with a Tapo or Kasa plug, turn it off after the print and see the energy each print took.
Send from your slicer.
Upload straight from the slicer and start the print in the same click.
Bambu LabBeta
Bambu Lab printers,
right next to the rest.
PrintPi talks to Bambu Lab printers over your local network. The Pi finds them by itself, you enter the access code once, and they appear in the same dashboard as your USB printers, with their camera, the AMS and HMS alerts.
- X1 Carbon, X1E, P1P, P1S, P2S, A1, A1 mini, H2D, H2S and X2D
- AMS slots matched to your spools, filament booked per slot
- Send .3mf files with their plates straight to the printer
- Watch in any mode, full control with Developer Mode
History
Every print leaves
a postcard.
When a print ends, PrintPi puts together what happened: the photo of the part, the time it took, the filament and energy it used and what it cost. Share it in one tap, or find it later in the history next to its timelapse.
- Photo, timelapse and figures for every print
- Filament booked on the spool that was loaded
- Print it again from the history
Filament
Your whole shelf,
always up to date.
Every spool with what is left on it, counted down while you print. PrintPi warns you before a job needs more than the spool holds, and walks you through loading and unloading at the printer.
- Over 800 filaments from Prusament, Bambu Lab, Polymaker and more
- A colour card of everything you own
- Cost per print from the spool's price
iPhone appSoon
Your printers,
in your pocket.
The PrintPi app for iPhone and iPad signs in to the same account and shows every printer at a glance. A running print stays on the Lock Screen, and your phone tells you the moment it is done or needs you.
Coming soon to the App StoreiOS 26 or laterFree with every plan
On the Lock Screen
The running print as a Live Activity and in the Dynamic Island, with the time left and a pause button.
Told when it matters
A push when a print finishes, fails, pauses or waits for new filament, with a picture of the part.
The camera in your hand
Live at up to 30 fps, full screen or picture in picture while you use other apps.
Send from any app
Share a G-code file from the slicer or Files to a printer. The upload carries on in the background.
Widgets and Siri
Printer status on the Home Screen and the Lock Screen, and a print you can pause by asking Siri.
The whole dashboard
Files with a 3D preview, the history with postcards and timelapses, filament, AMS and the terminal.
Touch panel
A screen at the printer.
Put a touch display on the Pi and the installer turns it into a panel: status, files, filament, the camera and moving the head. Big targets for dusty fingers, and a stop you have to slide, so nothing cancels a print by accident.
How it works
Online in three steps.
A USB cable doesn't reach the internet, so a small computer at the printer does the talking. A Raspberry Pi is perfect for it.
Install on the Pi
Plug the printer into a Raspberry Pi, or put the Pi on the same network as a Bambu Lab printer, and run one command.
Enter the code
The Pi shows a short code. Type it into your account and the printer is yours.
Print from anywhere
Phone, laptop or the screen at the printer. It's the same PrintPi everywhere.

The Pi only connects out. Nothing to change on your router, no VPN, no dynamic DNS.
Keeps printing offline
The file is on the Pi before the first line goes out. If the internet drops, the print goes on and the history catches up later.
Encrypted in transit
Every connection between the Pi, PrintPi and your browser runs over TLS. Each daemon has its own token you can revoke.
One small program
The Pi runs a single native program of about 10 MB. No Python, no Docker, nothing else to look after.

Which printers work with PrintPi?
Every printer with Marlin-based firmware on USB: the Original Prusa MK4S, MK4, MK3S+, MINI+, CORE One and XL, Creality's Ender and CR series, Anycubic, Elegoo, Artillery, Sovol, FLSUN and many more. If your printer takes G-code over a USB cable, it very likely works. Bambu Lab printers join over the network, see below.
Does PrintPi work with Bambu Lab printers?
Yes, in beta: the X1 Carbon, X1E, P1P, P1S, P2S, A1, A1 mini, H2D, H2S and X2D. The Pi reaches them over your local network with the printer's access code, so no USB cable is needed. PrintPi shows status, camera, AMS and HMS alerts in any mode; with Developer Mode switched on in the printer's settings it also starts, pauses and cancels prints and loads filament from the AMS.
What do I need at the printer?
A Raspberry Pi 3, 4, 5 or Zero 2 W with Raspberry Pi OS Lite (64-bit), connected to the printer with a USB cable. Any other 64-bit computer with Debian or Ubuntu works too. For a Bambu Lab printer, the Pi only has to be on the same network. A USB webcam is optional.
Do I have to open ports or set up a VPN?
No. The Pi connects out to PrintPi over an encrypted connection, the same way your browser opens a website. Nothing on your router changes.
What happens when my internet goes down?
The print keeps going. PrintPi copies the file to the Pi before the first line is sent, and the printer is driven from there. The history, timelapse frames and notifications wait on the Pi and catch up once the connection is back.
Can one Pi run several printers?
Yes. Plug several printers into the same Pi, add each one in the dashboard and switch between them in one click. You can link as many Pis to your account as you like.
How do I send files from my slicer?
Drop them on the page, or send them straight from PrusaSlicer, OrcaSlicer, SuperSlicer or Cura: add PrintPi as a physical printer with the API key from the settings. Plain and binary G-code both work.
Which cameras are supported?
Any USB webcam on the Pi, or a camera that serves snapshots or an MJPEG stream on your network. You watch it live in the browser in three quality levels, and every print gets a timelapse.
Is there an app for my phone?
Yes, for iPhone and iPad with iOS 26 or later, coming soon to the App Store. It signs in to the same account and is free with every plan. It shows the running print on the Lock Screen, sends a push when a print is done or needs you, and brings the camera, files and history along. On any other phone the dashboard works in the browser.
Can I put a touch screen at the printer?
Yes. Attach a display to the Pi and answer "yes" when the installer asks. It starts the PrintPi panel on the screen by itself, signed in to your account, and shows only what the printer needs.

when you are.
Create an account, run one command on the Pi and start your next print from wherever you are.
