PrintLapse 3D Print Timelapse

PrintLapse turns your phone into a small camera server on your Wi-Fi network. Your printer tells the phone when to take a picture — one frame per layer, always at the same point in the print — and the app renders those frames into an MP4 right on the device.

HOW IT WORKS

1. Create a project and open the camera screen.
2. Turn on Network Trigger in Settings. The app shows your phone's address, for example 192.168.1.42:5000
3. Have your printer send a simple HTTP request to http://:5000/foto-cek on every layer change.
4. When the print finishes, choose a frame rate and hit render. The video is saved on your phone, ready to share.

Step 3 works with anything that can make a web request at layer change: Klipper/Moonraker macros, OctoPrint, Home Assistant, a shell script, or plain curl. There is nothing to install on the printer itself.

Don't want to touch your printer configuration? You don't have to. Capture frames with the on-screen shutter or the volume buttons and the app handles the rest.

FEATURES

• Layer-synced capture over your local network — a plain HTTP GET is all it takes
• Manual capture too: on-screen shutter and volume-button shutter
• Projects: every print keeps its own frames, frame counter and thumbnail
• Built-in gallery to review your frames and share the finished video
• On-device H.264 / MP4 rendering — nothing is uploaded, nothing is queued on a server
• Pick your output frame rate and rotate the video in 90° steps
• Exposure lock, so brightness doesn't flicker between frames
• Standard or maximum resolution, and Full / 9:16 / 3:4 / 1:1 framing
• Front or rear camera
• Optional motorized camera slider (ESP32 rail over Wi-Fi): tell PrintLapse how many layers the print has and the rail advances one step per layer for a moving, cinematic shot
• Runs as a foreground service with a wake lock, so the connection survives long prints and a sleeping screen

GOOD TO KNOW

• Keep the camera screen open during the print — that's where the camera is live. Plug the phone in for long jobs.
• The phone and whatever sends the trigger must be on the same Wi-Fi network.
• Frames and rendered videos are stored in the app's own folder on your device.

PRIVACY

No account, no sign-in, no server of ours. Your photos and videos never leave your phone unless you share them yourself. The local web server only listens on your Wi-Fi network and only answers two requests: a capture trigger and a status check.

Made for makers who want their prints to look as good on screen as they do on the plate.

Recent changes:
• Camera permission is now a single step: the phone's own permission prompt opens right away.
• Much more reliable camera slider connection. If the link drops, it reconnects on its own and sends any layer it missed in between.
• A warning now appears on the camera screen when the slider's start or end point hasn't been set.
• The system navigation bar is hidden, giving the app the full screen.
• Smaller app size.
• Fixed a crash when taking photos on Android 8.
• Android 16 support.
