How do I live stream my 3D printer?
A 12-hour print is only content if viewers can see what is happening. Streaming a 3D printer means getting two things onto your broadcast — the live status (progress, temperatures, ETA, current layer) and the printer camera — ideally without port-forwarding or handing your printer to a cloud account. Here is how.
What you are putting on stream
There are two feeds. The first is status data your printer already reports — Klipper/Moonraker and Creality printers expose progress, nozzle and bed temperatures, ETA and the current layer over your local network. The second is the printer camera, if it has one.
The safe way to bring both in is a small agent on a computer on the same network as the printer. It reads the printer (never writes to it) and bridges the data and camera up to your overlay over one encrypted connection — so nothing about your printer is exposed to the public internet.
Read-only matters
A stream integration should only ever watch your printer, never send it a command. That way there is zero risk to a running print, no matter what happens on your channel. Look for an integration that is explicitly read-only for both the status and the camera.
Bonus: go live automatically
For an unattended, timelapse-style build channel, the nicest touch is auto-starting the stream when a print begins and stopping it when the print finishes — so your printer effectively runs its own channel.
Frequently asked questions
Do I need to expose my printer to the internet?
No. A local agent on the same network reads the printer and bridges the status and camera up over an encrypted connection — your printer stays on your LAN.
Which printers are supported?
Klipper/Moonraker printers and Creality (K2-style) printers are auto-detected; Moonraker API-key auth is supported for locked-down setups.
Can it control or pause my print?
No — the integration is strictly read-only. It only ever watches status and camera, so there is no risk to a running print.
