The short version, brand by brand
This is a set-up guide, not a security verdict. It records what each manufacturer’s own documentation says on 30 October 2026 about printing without its cloud service and about the data its services collect. Firmware and app behaviour change, so check the linked page for your exact model before you rely on a feature.
| Brand and example | Local-only route documented | Offline media | What you lose locally | Account deletion |
|---|---|---|---|---|
| Bambu Lab (A, P1, P2S, H2, X series) | LAN Only mode, bind in Bambu Studio with access code [1] | Micro SD card; required for X1 LAN prints [1] | Bambu Handy, remote start outside your network, print history [1] | Deletion request route listed in Bambu Handy’s Google Play data-safety section [2] |
| Anycubic (Kobra S1) | LAN mode, add printer in Anycubic Slicer Next without an account [3] | Not covered on the LAN page | Cloud service, app control, AI spaghetti detection [3] | Not stated on the pages we checked |
| Creality (K1C) | LAN printing via Creality Print [4] | USB flash disk printing [4] | Cloud printing and Cloud time-lapse records need the device linked [4] | Request termination; some data retained for fraud and support [5] |
Bambu Lab: enabling LAN Only mode
Bambu describes LAN Mode as letting the printer talk to the slicer on your local network for sending files and monitoring without internet access, and suggests it for sensitive models. With it on, you cannot start prints from outside your network, Bambu Handy is unavailable and print history does not work [1].
On X1 printers, spaghetti detection runs locally. Without a cloud connection, and with the user-improvement option off, the printer relies on the detection data in its latest firmware, so Bambu recommends updating firmware regularly [1]. X1 printers also need a micro SD card inserted to start a LAN print from Bambu Studio [1].
- A series: Settings, scroll to page 3, LAN Only Mode, switch on until the button turns green [1].
- P1P and P1S: Settings, WLAN, LAN Only Mode, confirm Yes, then note the access code [1].
- H2, P2S and X series: Settings, LAN Only, switch on, then choose whether to allow LAN liveview; Developer Mode lets third-party software control the printer [1].
- In Bambu Studio: open the printer list on the Device page, pick the printer with the lock icon, enter the access code and confirm. Discovery can take 20 to 60 seconds, and guest networks can block it [1].
- Different subnet or VLAN: bind with IP address plus access code. Bambu Studio does not store the IP, so you re-enter it after each restart [1].
Anycubic and Creality: local printing routes
Anycubic’s Kobra S1 LAN guide says LAN mode lets Anycubic Slicer Next send prints, check progress and view video on your local network, and states that all data stays local to the machine [3]. Turning it on disconnects the printer’s cloud service, the app can no longer control it, and AI spaghetti detection cannot be enabled. Only Anycubic Slicer Next is supported for this mode [3].
The Anycubic steps are: update firmware, update Anycubic Slicer Next, enable Settings, Network, LAN Mode on the printer, then in the slicer choose Workbench, Add Printer and scan the local network. Method 1 on that page is explicitly “without an account”. If scanning fails, read the Wi-Fi IP from the printer’s LAN Mode screen and enter it manually [3].
Creality’s K1C user manual lists three print routes: USB flash disk printing, LAN printing through Creality Print after binding the machine to the LAN, and Creality Cloud printing after binding a device in the app [4]. The AI camera can be viewed in Creality Print or the Creality Cloud app, and time-lapse videos can be exported to a USB flash disk from the printer’s own menu, while viewing them in Creality Cloud requires the printer to be linked first [4].
What the app listings and policies say is collected
The Google Play data-safety sections give the clearest app-level view. Bambu Handy’s listing says the app may share crash logs, diagnostics and other app performance data with other companies for analytics, and may collect name, email address and user IDs, plus optional precise location, photos and videos. It says data is encrypted in transit and that you can request deletion [2].
Creality Cloud’s listing declares the same kind of shared performance data and says the app may collect device IDs, optional photos and videos, and personal information such as name, email address, address and phone number, again with encryption in transit and a deletion-request route [6].
Creality’s privacy policy on creality.com covers website use, including automatically collected IP address, browser and device characteristics. It says that when you ask to terminate your account it will deactivate or delete it, while keeping some information to prevent fraud, troubleshoot problems and enforce its terms [5]. This guide does not cover Bambu Lab’s or Anycubic’s full privacy policies; the Anycubic row relies on its wiki statement that LAN-mode data stays local [3], so read each policy directly before you decide.
Choosing a set-up
If you want phone notifications and remote starts while away from home, the cloud account is the price of that convenience on all three brands. If you print at home and are happy to start jobs from a computer on the same network, each brand documents a local route, but each removes something: Bambu Handy on Bambu [1], app control and AI detection on the Kobra S1 [3], and cloud records on Creality [4].
- Before switching to LAN mode, update firmware first; Anycubic lists it as step one [3].
- Keep the access code or printer IP somewhere safe; Bambu Studio asks for the IP again after restarts when you bind by IP [1].
- If you print sensitive models, note that Bambu’s own LAN guide suggests LAN Mode for models that need to be kept private [1].
Questions before you decide
Can I use Bambu Handy with LAN Only mode on?
No. Bambu’s wiki says Bambu Handy is not available in LAN Mode, and remote printing from outside the local network and print history also stop working.
Do I need an Anycubic account to print over my network?
Not on the Kobra S1. Anycubic’s LAN guide includes a method to add printers on the local network in Anycubic Slicer Next without an account, after enabling LAN Mode on the printer.
Can I watch the camera in Bambu LAN mode?
Yes on documented models. Bambu’s guide has a LAN Only Liveview option for H2, P2S and X series printers, and on A series printers the live view appears in Bambu Studio after binding.
Can a Creality K1C print without Creality Cloud?
Creality’s K1C manual lists USB flash disk printing and LAN printing through Creality Print as print routes separate from Creality Cloud printing.
